Obituary Lucius E. Sayre Dean Lucius Ε Sayre, of the College of Pharmacy. University of Kansas, died a t his home in Lawrence, Kans , July 21 at the age of 78. H e was born in Bridge ton, N. J., in 1847 and grad uated from t h e Philadelphia College of Pharmacy and Science. The University of Michigan conferred an honorary B.S. upon him in 1896 and his Alma Mater honored him with the P h . M . degree. From 1882 to 1885 he was engaged in pharmaceutical manufacturing and from 1880 to 1885 he was an instructor a t the Philadelphia College of Pharmacy. He became dean of the College of Pharmacy a t the University of Kansas when t h a t college was organized in 1891 and remained at its head until his death. Dean Sayre was an ex-president of the American Pharmaceutical Association and served on the Revision Com mittee of the U. S. Pharmacopeia since 1890 He was director of drug analysis for the Kansas State Board of Health and a member of the botanical staff of the Kansas Board of Agriculture. I 'can Sayre was the author of several texts on materia medica, pharmacognosy, and botany. He is survived by two sons and two daughters. His kindly interest in his students and his un selfish devotion t o the professions which he graced for so many years are remembered by all who had the opportunity of coming in contact with him.
Carbide and Carbon Chemicals Corporation The Carbide and Carbon Chemicals Corporation announce t h a t commercial production of ethylene glycol, ethylene dichloride and related compounds has been started in their new plant a t South Charleston, West Virginia, following extensive research and semi-commercial experiments. Ethylene glycol is a colorless, odorless liquid whose character istic properties are intermediate between those of alcohol and glycerol. It is soluble in water with a marked lowering of the freezing point, is hygroscopic as is glycerol, a preservative as is alcohol, and an excellent solvent for vanillin, coumarin, and some of the essential oils. Its solutions are nontoxic and physio logically harmless. I t is used as an anti-freeze for automobile

radiators and as a constituent of organic brines for refrigerating purposes. It is a raw material for the manufacture of nitroglycol, a constituent of low freezing dynamite. It finds many uses as a solvent. Ethylene dichloride boils at 83° C , is insoluble in water, a n d will dissolve oils, gums, resins, and fats. It is used in admixture with alcohol as a solvent for cellulose esters. It is noncorrosive to metals and burns only with difficulty. Its halogen atoms arc readily replaceable by hydroxyl, amino, or cyanogen groups yielding di-substitutcd compounds. It is an excellent solvent and finds wide use in this field. Quantity production of these compounds has effected a considerable price reduction and thus makes them available for wider use. In addition to these two, this company is also producing in quantity, ethylene chlorohydrin, ethylene oxide, diethyl sulfate, isopropanol, hydrocarbon gases for refrigerating purposes, and compressed hydrocarbon gas for use where coal gas is not available.
Measuring Sulfur on Foliage Determination of the amount of sulfur present on sprayed or dusted leaves at the time of and subsequent to application is of obvious importance in determining whether the fungicidal material is present within the limits necessary to give successful protection, as well as to provide data for deciding on the frequency of applications. The author's method is to immerse typical samples of sprayed or dusted leaves in carbon tetrachloride, which is then heated to ensure solution of the sulfur, after which it filtered. The filtrate is then evaporated and the sulfur residue weighed. Tests thus made a t various intervals after application indicate t h a t immediately after application apple foliage retained 67 86,', of the sulfur applied in lime sulfur, while dusted leaves showed an adherence of 36 66 , ; the loss of sulfur during the first few days after application WLIS often rather rapid, particularly when dust was used. When the sulfur recovered was above 40 milligrams per 10 leaves (the sample employed) on either dusted or sprayed trees, there appeared to be adequate protection against scab. Λ use of this method promises to be of value in ascertaining the maximum and minimum amount of spray or dust needed as well as the interval that may safely pass between successive applications; these points to be considered with due regard to rain, wind, additional leaf growth and uniformity of applica tion.— H.
