Microchciiiical Symposium Held in Jew York A STAFF REPORT

A HK third annual mi croche mi cal sym­ posium of t h e Metropolitan Microchemical Society was held at t h e American Museum of N a t u r a l H i s t o r y in New York City on Feb. 27 to 28. T h e two-day meeting which drew over one hundred microchemists from t h e metropolitan area consisted of t h r e e technical sessions each of which was presided over b y a former chairman of t h e organization: D. B . Sabine, R o b e r t A. H a r t e , Leo K . Yanowski.

College presented some discussion on t h e use of microchromatography employing filter paper partitioning. T h e author said t h a t although this technique was suggested in 1861 by Schonbcin it received little attention until 19-14 when Consden, Gordon, and M a r t i n published their paper o n the qualitative analysis of pro­ teins i n which t h e y employed a partition chromatographic method using paper. The latter application differed somewhat from t h e original b y using t h e paper only as an inert support for the two solvents, Block revealed. Statistical methods, a field that h a s been receiving increased attention a t most technical meetings, was the t h e m e of t h e paper b y John Mandel of t h e National Bureau of Standards. T h e author indi­ cated that such methods serve a twofold

purpose in analytical chemistry research: the design of experiments and t h e analysis of data. For this* r e a s o n , it i s necessary t h a t t h e statistician be consulted in both the planning a n d t h e evaluation stages of experimental work. Some of t h e diversifiecl applications of the automatic recording; spectrophotom­ eter were revealed in th-e paper by E . I. Stearns of t h e American* Cyanamid Co. Among the illustrations u s e d by the author were the determination of a reaction b y the formation of a chemical complex between a dye molecule and a rmetal, the deter­ mination of a reaction ra,te by the inver­ sion of sucrose and t h e determination of the optical constants of &, printing ink by the determination of the refractive index and the extinction coefficient o f an alkali blue ink.

After a welcome t o t h e gathering b y F. A. Meier, of the American P l a t i n u m Works, t h e present chairman of t h e Metropolitan Microchemical Society, t h e technical sessions got under way with a paper b y Iv. J . Heinicke of Bausch a n d Lomb, λνΐιο spoke of recent developments in t h e field of microscopy. T h e author declared t h a t ultraviolet microscopy h a s been revived b y more efficient screens for focusing, more suitable light sources, a n d optical developments covering a greater range of ultraviolet wave lengths achromatically. T h e a u t h o r concluded his paper b y stressing t h e importance t h a t developments of chemicals fluorescing in t h e infrared will h a v e in use of t h e same for focusing screens in infrared photo­ micrography. Infrared spectroscopy was t h e topic dealt with in t h e paper b y K o n r a d D o b riner of t h e Sloan-Kettering I n s t i t u t e . H e pointed o u t t h a t with t h e increased availability of a d e q u a t e instruments with which t o make infrared absorption meas­ urements, i t i s expected t h a t infrared techniques will play larger roles in bio­ logical research. T o prove his contention, t h e a u t h o r described t h e use of infrared spectrometiy a s an analytical tool in t h e determination of small quantities of steroid metabolites isolated from urine. N o t only did i t prove useful in recognizing these compounds, t h e a u t h o r concluded, b u t i t gave helpful information on t h e position of functional groups in t h e steroid molecule. R.

Fuel Policy.'' In this article general ap­ proval was given to the proposal of Sec­ retary of the Interior Kring to fctie Congress of the United States for expenditure of $9 billion over t h e next five years in con­ struction of synthetic fuiel plants specifi­ cally for the synthesis of gasoline and fuel oil. Y e t I find no word 03:1 the t r u l y sound program based upon fenra.enlation alcohol. I t is to be regretted thiat authorities in Washington a r e totally olbliviotis to chemurgic progress and especially t o enzymatic studies. Only oflate h a v e they become at all cognizant of the passing of petroleum! Since i t s introduction in 1859 i n Pennsyl­ vania somewhat over 20 îbilliori barrels, or less t h a n one cubic mile, o f the liquid have been consumed; and o n l v about 24 billion barrels remain in our prov^ed reserves, t o be increased, f r o m time to fcimc, b y new and always more costly findiogs, T h e present rate of consumption of petroleum i n this c o u n t y amounts to 1.8 trillion barrels annually, which is slightly above our present annual explorational findings, The calculated home requirements of 2 billion barrels of liquid fuels b y 1949 m a y well stir national authorities t o ponder t h e predictions and promises of w a price as $2.00 {Continued on p*age 8O6) 743
