MILLEE>GEVILLE, G A . - E n t e r i n g a plea for the profession o f analytical chemistry as the solid foundation upon which vir tually all progress i n chemistry must rest, A. E. Bailey addressed t h e members of t h e ACS Georgia Section a n d students and faculty g a t h e r e d at Georgia State College l o r Women h e r e NAay 3 on t h e occasion of the annual Herty Day celebration. Dr. Bailey, d i r e c t o r of research at H u m k o Co., M e m p h i s , is t h e 20th recipient of the Herty Medal p r e s e n t e d every year by t h e Georgia Section. The young person who aspires to mak i n g alastingcont r ibution to science, Bailey .stated i n his medal address, cannot do better t h a n to devote himself t o analytical chemistry. To illustrate t h e importance of t h i s branch of chemistry, Dr. Bailey turned to his o w n field, fat and oil chemistry. H e cited t h e difficulties which were experi enced urp until only 11 years ago in de t e r m i n i n g the fatty acid composition of so common an o i l as linseed oil. W i t h t h e advent o f an accurate m e t h o d based on tfiiocyarogen absorption developed b y G. S.

vious approximations shows startling dis crepancies. Since that time, he said, great strides have been made in analytical tech niques applicable to fat chemistry, par ticularly in ultraviolet a n d infrared spec troscopic methods for determining un saturated fatty acids. Avoiding Overspecialization Of Scientific Knowledge Young chemists these days are almost invariably admonished to beware of nar rowness and overspecialization a n d to cul tivate scientific knowledge of a wide var iety, Bailey remarked. Although agreeing with t h e philosophy behind this advice, Bailey thought there was a little confusion as to h o w t h e broadening of knowledge and interests m a y best b e accomplished. For the young individual w h o is ambitious and alert, this will more or less take care of itself. It would not b e appropriate to suggest, for example, that a young organic chemist spend much of his time in attempt ing to master physical chemistry, biochem istry, t h e economics of his raw materials, or engineering principles. Rather, h e should apply his knowledge of organic chemistry to his own' particular job and

Device Up Results
A laboratory instrument that can make a complete molecular analysis of a 20-component hydrocarbon mixture in 10 minutes, and then type out the results on a paper tape was described at a recent analytical chemistry conference. Made by hooking together a mass spectrometer and an electronic computer, the new device contains a specially developed selector which codifies the output of the spec trometer into a form which can be fed directly into a digital computer. The latter then solves the equations necessary to determine the exact quantities of the various components in the mixture. Previously, readings of the spectrometer were either calculated by hand or fed into a simultaneous equation computer to obtain the results. A simple mechanical arrangement allows the results from the com puter of the new instrument to be reproduced in typewritten form, it is said. Time required for a complete analysis is claimed to be about one-tenth of that required for the most rapid previous methods, and only one operator is needed to run the instrument. One such in strument is now in operation, and the design will be made available after further testing, according to the company.
F o o d f o r Thought Given a little more time, nutritionists should one day be able to de-flavorize cold mutton, add a pinch of powder, and make it come out lobster thermidor, according to recent ob servations of a bio-chemist. Perception of flavor, he says, depends upon taste and smell— senses that function like an efficient labora tory because they can identify in a fraction of a second compounds it would take a chem ist days to analyze. Science has learned that taste and smell of most things come from minute amounts of closely associated chemical substances. Some of these essences have been successfully extracted, and many of them can be duplicated in the laboratory. In addition, chemists have determined the nature of the molecules to which the senses respond and are now able to design a few tastes and aromas at will, according to this authority.

Past work in connection with the U.S.P. vitamin A animal assay diet has indicated that vitamin B12 may have some interrelationship with vitamin A in the body. New research at a leading university has demonstrated that vitamin B12 can increase storage of vitamin A in the body. Results of tests with animals showed that vitamin B12 given every other day by intramuscular injection caused a 40 per cent increase in the amount of vitamin A deposited in the liver and kidneys of animals receiving carotene in their rations. "When i t was administered orally, vitamin B12 in creased vitamin A storage derived from caro tene by 26 per cent. U.S.I, is a major producer of primary fer mentation vitamin B12 feed supplements which have been shown to cause an even greater growth response than pure vitamin Β12. These supplements are among the best available for use by feed manufacturers in poultry, turkey, hog. and calf rations.
Rare Earth Metals Not So Rare Any More Interest in the rare earth elements is under going a revival as one of the results of the atomic energy program, according to a recent report. These elements make up an appreci able fraction of the fission products of atomic piles, it is said, and one phase of their study has been the successful production of kilo gram quantities of several of the rare earths in the pure state. The method used involves reducing the anhydrous rare earth chlorides with calcium in a refractory oxide-lined con tainer. Iodine is added to the reaction mix ture, and by its highly exothermic reaction with calcium liberates sufficient heat to give a well-fused mass of the product metal. Vac uum remelting removes all but trace amounts of calcium. Quantities of lanthanum, cerium, praseodymium, and neodymium have been produced in this manner, all with purities greater than 99.7 per cent. Because of their unique similarity, pure rare earth metals are valuable in the study of other metals and of the relationships between their properties and their electronic structures.
modified maleic which imparts hoth hardness and excellent cold check resistance to its formulations, making it an ideal resin for use in all interior-type lacquer finishes. It is particularly well suited for furniture sealers and finish coats. "7*.'. - v >^'-'--r^^
Conventional maleic resins have been found satisfactory in most respects for interior lac quers. They generally permit the formulation of fast drying, good sanding and good rubbing products with high print resistance. However, to attain these properties, considerable sacri fice must be made in resistance to cold check ing. The ratio of short oil, non-oxidizing alkyds to maleics is often increased in lacquer formulations to overcome the cold checking properties, but the ease of sanding and rub bing, fast drying, print-resist ant qualities are often reduced MORE to some extent as a result.
Vinyl Paint Systems Described in N e w Booklet A bulletin recently offered to the public describes the characteristics and application methods of a vinyl base plastic paint which is claimed to give protection against marine atmospheres, tropical climates, chemicals, abrasive action, salt water corrosion, and simi lar conditions. The bulletin explains the sys tems used for painting metals, concrete, brick, stone, piaster, and asbestos board, and out lines uses of the coating in such industries as chemical processing, food and dairy, public utilities, petroleum, marine and railroads.

A R O C H E M 5 4 2 Solves t h e P r o b l e m AROCHEM 542 eliminates the need for a compromise between these two sets of prop erties. Used as a direct replacement for the maleic resin component in lacquers, it con tributes greater ease of sanding and rubbing even though it has a lower melting point. The relatively low melting point of this un usual resin is not indicative of the excellent hardness it imparts to finishes. The resistance of A R O C H E M 542 to cold checking is also vastly superior t o that of conventional maleics. For example, cold check tests on a typical furniture finishing system, films of which were aged one month, snowed that AROCHEM 542 systems passed 10 to 15 cycles while conventional maleic resin lac quers failed in 2 to 4 cycles. In addition, maleic-alkyd combinations, adjusted to have cold check resistance comparable to that of AROCHEM 542 lacquers, were definitely in ferior to the latter in speed of setting, ease of sanding and rubbing, and print resistance. AROCHEM 542 lacquers have been found to be equivalent to their maleic counterparts in color and color retention as well as in re sistance to solvents, alcohols, and rubbing compounds.
