The average recovery of carbon disulfide by this method is about 96 per cent, assuming 100 per cent purity for the carbon disulfide used; however, analyses of the pure carbon disulfide alone showed about 98 per cent CSz. Almost faultless checks can be obtained in duplicate analyses on the same emulsion. This method estimates as carbon disulfide any sulfur present in an emulsion in any form which will be converted to sulfate by an alkaline peroxide solution. It is doubtful if any commercial carbon disulfide emulsion will contain more than a negligible amount of non-carbon disulfide sulfur. Of the two soap solutions used in making the emulsions employed in this work, the rosin-fish oil soap in emulsion No. 1 contained 0.10 per cent sulfur, corresponding to 0.02 per cent sulfur in the emulsion, while the rosin-oleic acid soap in emulsion No. 2 contained 0.00 per cent sulfur. For this reason it was not thought necessary to work out a method for determining non-carbon disulfide sulfur in these emulsions. Not all of the carbon disulfide is necessarily present in the free state in the finished emulsion; some of it may be combined, with the rosin or otherwise, and the method does not distinguish between that present in the combined and uncombined states,

HE production of medicinal substances on a large scale

is a relatively modern industry. Up t o the middle of the last century i t had been the almost universal custom for each pharmacist or apothecary or chemist, as he was variously known in different countries, t o prepare for himself such substances or compounds as he needed, but about this time the idea of centralized manufacture of medicinal preparations was beginning t o take root. In 1862 Samuel P. Duffield, a retail druggist in Detroit,.began t o make a number of preparations in larger amounts than required for his own use and sell them t o other pharmacists. Seeing the possibility of a larger business which could render useful service t o many and probably become financially profitable, Hervey C. Parke cast his lot with Dr. Duffield and there was founded, on October 26, 1866, the partnership of Duffield, Parke & Company. This is considered the birth of the present business. In January, 1869, A. F. Jennings bought the interest of Dr. Duffield and the firm became Parke, Jennings & Company, with Geo. S. Davis as one of the company. On November 16, 1871, Dr. Jennings retired from the firm and i t became Parke, Davis & Company, a co-partnership. Thus it continued for a few years, but with the business developing rapidly i t seemed desirable to perpetuate i t in some better form; so on January 14, 1875, i t was incorporated With a capital stock of $125,000, of which $81,950 was paid in. Today the business is represented by five million shares of no-par-value stock selling on the market a t about $30 per share. Besides the main laboratories in Detroit, there are also manufacturing laboratories in Walkerville, Canada; London, England; Syndey, Australia; Rio de Janeiro, Brazil; Santiago, Chile; and Havana, Cuba. There are fifteen branch offices in the United States, three in Canada, and ten in various foreign countries. In fact, there is practically no place in the world t o which the medicinal products of Parke, Davis & Company d o not reach.

The present directors of the business are 0. W. Smith, president; N. H. F. McLeod, secretary and treasurer; David Whitney, A. H. Buhl, and Jerome Remick, vice presidents; I,. B. Hayward, superintendent of manufacturing; and Henry Ledyard.

Guiding Principles In the development of great enterprises permanence and virility are determined not so much by personalities as by principles. Outstanding personalities may come and go, but the dominating principles whereby they express in business the best of their abilities may continually develop and give t o that business the ardor and strength of perpetual youthfulness. In the early days of Parke, Davis & Company the desire for immediate profit was made subservient to the hope of future growth, and the principle of being satisfied with nothing but the best that science could produce became the cornerstone of this commercial structure. The ideas which imbued the founders of the business, and which have been perpetuated through changing generations of control and ownership, may well be illustrated by a quotation from a little leaflet printed many years ago when the firm was very young, entitled “Our Creed and Code:” We believe that in combating disease only the best quality of drugs is permissible and that to their manipulation should be applied the highest scientific skill. We believe t h a t the issuing of inferior medicines of any kind is unjustifiable from any point of view. We believe in standing solely on the intrinsic merits of our preparations and in making no false pretenses; in doing the best that scientific knowledge and skill will accomplish and in doing it honestly and faithfully. We believe in working fully in harmony with our pharmacal and medical friends in gratefully accepting any suggestions t h a t may tend to our mutual profit. Our watchwords are Purity, Accuracy, Reliability. This same spirit permeates the whole organization at the present time, and when it is noted that the majority of shareholders,

have repeatedly been devised. Years ago they developed new and unique apparatus for manufacture and perfect coating of pills, so that a single complex machine would produce more than a hundred expert individuals could originally do and that with greater accuracy. Likewise, many improvements were brought about in the manufacture of tablets of various kinds; as, for example, those relating t o unusual solubility of hypodermic tablets, rapid disintegration of compressed tablets, and the production of a special coating resistant t o the action of the stomach digestion but readily soluble in the small intestine, the resistance of which could be more accurately controlled than previously used coatings of this type. Gelatin capsules were produced elsewhere as early as 1833, but no material improvements had been made up to about 1875 and they were but little used. In that year Parke, Davis & Company began t o supply them as made by an associated factory of which they controlled the entire production. This was subsequently taken over as an integral part of the firm, new automatic apparatus was invented, both for the manufacture of empty capsules of extraordinary perfection and for fully automatic filling of such capsules with medicaments, until today this plant is the largest producer of capsules in the world. In more recent years, with a growing tendency toward hypodermic and intravenous medication, much research has been devoted t o the best means of preparing and stabilizing such solutions, involving the study of effects of minute impurities in materials used; the action of light, oxygen, and inert gases; the effect of pH concentration; the action of different qualities of glass upon solutions and numerous other special considerations. Digestive Enzymes The gradual development of this class of medicinal substances by the laboratories of Parke, Davis & Company well illustrates the commercial value of patient and continued research. PEPSIN-In 1874 they introduced a saccharated pepsin of such strength that “5 grains would digest 60 grains of coagulated albumin,” thus being of a 1:12 strength. Today that would be considered so weak as to be absolutely useless. In 1881 appeared a product dignified by the name “concentrated” of a 1 : l O O strength, but in 1883 this was displaced by a 1:500 pepsin. By 1888 a 1:2000 pepsin, relatively non-hygroscopic, was placed on the market, and by 1893 strengths of 1:3000 and

PANcREATIs-Less spectacular but important gradual improvements have been made in both the quality and strength of pancreatin, and a substance having three times the activity of the U. S. P. standard is regularly available. TAKADIASTASE-ASa result of the researches of Dr. Takamine, this company in 1895 for the first time marketed an enzyme for medicinal use, derived from certain species of fungi and having unusual potency in the conversion of starch into assimilable forms, one part being able t o convert three hundred times its weight of dry starch. This has come into wide use. Biologicals During the years 1887 to 1894 the thought that immunity against various diseases of bacterial origin could be produced in animals and human beings was the subject of much scientific work, culminating in that of von Behring and Roux, which definitely marks the beginning of the idea of producing on a manufacturing scale a substance that would produce immunity against diphtheria. This company, recognizing the great medicinal value of such a product and the possibilities in the field so opened up, established in 1894 a department for pharmacological work and the production of diphtheria antitoxin. It was their successful fight against the von Behring patents that made it possible later for all in the United States, who so desired, to make diphtheria antitoxin without the necessity of paying a royalty on foreign patents. In 1898 they brought out for the first time a package containing 3000 units of antitoxin. The first serum made contained about 50 to 60 antitoxic units per cubic centimeter. Since that time a great amount of research has been given by these laboratories to methods of producing more concentrated serum as free as possible from excess of inert albuminous substances, with the result that they are now supplying a serum with a potency of 3000 or more units per cubic centimeter, and researches still continue. I n 1897 antistreptococcic and antitetanic serums were added and then followed numerous other important preparations of bacterial origin. The first line of bacterial vaccines was put out commercially by this company in 1907. A very recent development of the research laboratories is a series of “immunogens,” improved products for development of active immunity against a number of pathogenic bacteria. Among other important biological medicinals introduced by

1:4000 were regularly supplied, while up to 1: 15,000 could be made. This 1:15,000 pepsin was probably considerably weaker than one that meets the tests of today a t t h a t figure. Now 1: 15,000 strength may be readily supplied and in the research laboratory as high as 1:42,000 strength has been obtained.

AMERICAN CONTEMPORARIES J. B. Francis Herreshoff

I

T WAS the late summer of 1888 that I first had the privilege

and joy of meeting Francis Herreshoff. He was then thirtyeight years of age, and I, less than twenty-two, seeking for a start in the chemical industry, had a definite appointment and clear-cut instructions from William H. Nichols to come to an understanding one way or another. Herreshoff impressed me tremendously, and I have never ceased to respect and admire his simple sincerity-a sort of guilelessness, with a complete absorption in his profession. We talked for two hours a t the old Pierrepont Hotel in Brooklyn, where he was living while his family were away for the summer; and now that I know him so much better, there is no doubt t h a t he would have talked for many more hours, for he was interested in the young Scot and wanted to get a new point of view if pos.;ible. That was characteristic of him. He has always been alert and ready to forget time, if he could rehearse with a n interested listener the ideas that were afloat in his mind but not yet safe to deliver. He would think and talk and get a little clearer in his own mind until conviction possessed him, and then the listener would begin to discern t h a t his genius was carrying him a little in advance of the world. The endless discussions that were beginning to look verbose and futile were not in vain-the Teutonic thoroughness and tenacity of purpose, though slow in process, mere absolutely sure in accomplishment. At this first meeting I rose to take leave, as a longer interview was likely t o expose my inexperience and betray my limitations. Herreshoff stood up, his back to the wall, his head thrown backa perfect Apollo in physique-handsome as a dragoon, and while he stood there he continued expressing views and asking ques-

tions. I left, exhilarated and satisfied that the combination of William H . Nchols and Francis Herreshoff had all the qualities of success in admirable proportions. And there the matter dropped and nothing developed until the following February. Time meant nothing to Herreshoff until he saw exactly how to attain the object. Then he became positively impatient to construct, complete quickly, and operate efficiently and economically without further rehearsal or discussion. All the preparation was past and apparently forgotten long ago, though the details were still in the drafting office unfinished, while bricklayers, carpenters, and mechanics were ready to proceed on orders. He was christened John Brown Francis Herreshoff, and invested with the honorary degrees of b1.A. and D S c . by his Alma Plater. He had been deterred from completing his course a t Brown University. He was the youngest of a large family and did not wish to put his parents to the expense of putting him through college. However, he found that he could accomplish his object without expense by becoming an instructor of analytical chemistry a t Brown for three years-1869 to 1872. He then went into the laboratory of the Habirshaw Company in Pearl Street, doing analytical work until 1876, when William H. Nichols heard of his unusual qualities and ability, and decided to take a chance and have him direct the Laurel Hill Chemical Works, hoping that the rule-of-thumb methods could be superseded by scientific standards. Very little was accomplished in the first year of his control a t Laurel Hill. He wanted t o learn from the foremen, mechanics, and process man how to produce sulfuric acid industrially. It was not the chemical reaction in itself that gave trouble in work:
