make for success in research administration, Mr Weidlein not only directed the Institute’s work with a self-sacrificing skill which inspired the admiration of the donors and his associates, but he also found time to serve as chemical expert for the War Industries Board, in which positional capacity his attainments elicited the highest official commendation. With the patriotic concurrence of the donors of certain of the Industrial Fellowships, Mr. Weidlein was also enabled to direct a t the Institute a number of investigations of pressing importance to the War Department. Intimately associated with Mr. Weidlein during this trying period of intensive research effort were Assistant Directors Tillotson and Pratt, both of whom actively and constantly participated in establishing the conspicuous success of the researches conducted for the Government and for our industrialists. The present status of the Industrial Fellowships alone bears testimony to the high executive ability of these three men and their sincere devotion to the system and the Institute. During the year the administration was strengthened by the appointment of Mr. Harry S. Coleman t o an Assistant Directorship. Mr. Coleman is a mechanical engineer possessing splendid training and industrial experience, which peculiarly qualify him to assume supervision of certain of the Institute’s inquiries in the domain of mechanical technology. A constantly increasing number of investigations are coming to the Institute from that field, and three of the Industrial Fellowships now in operation largely involve experimental engineering work. The Administration of the Mellon Institute is now constituted as follows: RAYMOND F. BACON, Sc.D. Director EDWARD R. WEIDLEIN, M.A. Associate Director E. WARDTILLOTSON, Jr., Ph.D. Assistant Director PITTsA’OH,
WILLIAM A. HAMOR, M.A. Assistant Diiector Ph D. DAVIDS. PRATT, Assistant Director S COLEMAN, B.S. HARRY Assistant Director

BUREAU OF STANDARDS’ SAMPLES NOTICE OF CHANGE IN METHOD APRIL I,
OF DISTRIBUTION EFFECTIVE
1919
The Bureau of Standards reports that it is making strenuous efforts to renew its depleted stock of standard samples. The very great increase in the demand for these samples from regular sources and extra calls from the inspection sections of the War and Navy Departments together with the inability to get increased appropriations for this work have made i t very difficult to keep the supply adequate. The demands of the military branches of the Government have made it impossible to procure the material for the renewal oE some of the samples and have made it very difficult to procure the machinery for the preparation of the iron and steel samples. It may not be realized generally that the preparation of a sample consumes about three-fourths of the time required for the entire work upon it. The present method of distribution has been known for some time to be cumbersome. New ordering and shipping regulations have therefore been adopted and ordered published on two additional pages, 5 and 6, of the Supplement to Circular 25, “Standard Samples-General Information.” This new supplement can be obtained on request from the Bureau of Standards, Washington, D. C. As adopted, these regulations provide for the ordering of standard samples by number and name from the list printed on the first page of the above-mentioned supplement just as a t present. From this time forward all samples for points in the United States or its possessions will be shipped by parcel post, C. 0. D. Those for points in Canada, Mexico, and other foreign countries will be shipped by express, C. 0. D. The

regulations of the Department of Commerce require that the payments for these samples be in the hands of government agents before delivery can be made. By using the parcel post exclusively the Bureau hopes to make it possible for customers to send in their orders and pay for them through their own post office when delivery is made. They hope in this way to make prompter shipments and avoid the necessity for refunds when samples ordered are out of stock. The IO per cent quantity discount on 4 or more samples ordered a t one time has been discontinued. The Bureau has on hand a t present a fairly adequate stock of the following: Fee per Weight Sample of Sam- with SAMPLE CONSTITUENTS DETERMINEDple CertifiNo. NAME OR INTENDED USE Grams cate 1 Argillaceous limestone Complete analysis 100 $1.00 2 Zinc ore D Zinc 100 1.00 4b Iron B C Si Ti P S Mn 150 2.00 5 c Iron C C ’ S i ’ T i ’ P ’ S ’ M n Cu 150 2.00 7 Iron E C:Si: Ti; P,’S,’Mn,’ Cu, Cr, Ni V 150 2.00 86 Steel Bessemer 0.1 C C Si’ P S Mn 150 2.00 96 Steel: Bessemer: 0.2 C C’ Si’ I” $’ Mn 150 2.00 l l b Steel B 0 H 0 2 C C’ Si’ P’ Mn 150 2.00 12b Steel: B: 0: H:: 0.4 C C’ Si’ P’ S’ Mn 150 2.00 15a Steel B 0 H 0.1 C C’ Si’ P’S’ Mn 150 2.00 16a Steel: B: 0: H:: 1.0 C C: Si:.P: S:.Mn 150 2.00 17 Sucrose Calorimetric value and saccharimetric value 60 2.00 2.00 20a Steel, A. 0.

FRASCH SULFUR MINlNG PROCESS DECISION According to the Oil, Paint. and Drug Reporter for March IO, 1919, vast deposits of sulfur in the United States are opened up to all who would bring them to the surface, under a decision just handed down by Circuit Judges Buffington and Woolly, and District Judge Thompson, in the United States Circuit Court, sitting a t Philadelphia. The suit was instituted by the Union Sulfur Company, of Louisiana, against the Freeport-Texas Company upon allegation of infringement Of certain basic patents standing in the name of Herman Frasch, deceased, and taken over by the Union Company. This company alleged the FreeportTexas Company was infringing upon its rights. The case appealed from the District Court of Delaware sets a precedent in the history of sulfur mining. In briefest terms the decision of the court, which reverses the lower tribunal, is that the so-called Frasch patents cover methods and processes not of basic patentability, and that no control of certain mining methods is given by them. Sulfur deposits are, therefore, opened up and the studies and experiences which Frasch made and had are now available to the world.
