Student Chemists to M e e t ON
APRIL 26 approximately 200 student members, faculty, and guests of the Intercollegiate Student Chemists will as semble for their annual meeting a t Villanova College, Villanova,, Penna. T h e morning session will be devoted t o papers presented b y student speakers. Prizes, sponsored b y the Philadelphia Section of t h e AMERICAN CHEMICAL SOCIETY, will be
awarded for the two best papers. In t h e afternoon the group will go to T h e Franklin Institute in Philadelphia for a planetarium demonstration and con ducted tour of the museum. Special at tention will be devoted t o the new petro leum exhibit in the chemistry section of the institute. Member colleges of t h e Intercollegiate Student Chemists are Albright College, Drexel Institute of Technology, Franklin and Marshall College, Gettysburg College, Haverford College, Lafayette College, Lebanon Valley College, Muhlenburg Col lege, Swarthmore College, University of Delaware, Ursinus College, and Villanova College. All colleges in the Philadelphia area are invited t o send representatives t o t h e meeting.

Summer Conference of Chemistry Teachers FOLLOWING t w o very successful summer conferences, the N e w England Associa tion of Chemistry Teachers i s making plans for the Third Annual Conference to be held on the campus of the University of Con necticut, Storrs, August 12 to 15, 1941. The morning a n d afternoon sessions will be devoted to invited papers on topics of current interest pertaining t o the teaching of chemistry i n secondary schools and colleges and t o recent advances in the science itself. Speakers of national repute have been invited to participate. Meals and lodging w i l l be provided at a very low rate by the university, and accommoda tions for families will be available. A social program and industrial trips are being planned. There will b e a registration fee of $2.00 for members w h o register before August 1, and $3.00 for those who register later.
421 For nonmember chemistry teachers from New England or elsewhere, t h e ref ac tion fee is $5.00, part of which may be as dues in the association if member desired. Payment of the registration lee is not required of nonteaching guests or the families of teachers attending the con ference.
New Plant for 100-Octane Fuel Planned As ONE item in t h e Atlantic Refining Co.'s $7,750,000 expansion program, a plant for manufacture of 100-octane gasoline for u s e in military aviation is planned at the company's Point Breeze, Philadelphia, refinery. Other additions to refinery equipment scheduled in 1941 include a new catalytic cracking plant to supplement the new catalytic polymerization plant at Point Breeze, and an advanced type unit for the refinery a t Atreco, Tex.
Student Chemical Colloquium THE Rochester Section of the AMERICAN CHEMICAL SOCIETY is sponsoring the
fourth annual Student Chemical Collo quium which will b e held on t h e River Campus of t h e University of Rochester, April 25 and 26, under the auspices of the Chemistry Club of that university. T h e principal speaker will be C. Ε . Κ. Mees, vice president in charge of research and development of the Eastman Kodak Co., who will speak on the "Development of Kodachrome". This talk will be given in the Alvah Strong Auditorium, Univer s i t y of Rochester, o n April 25 at 8:00 P. M. T h e purpose of the colloquium is to permit students t o present reports on senior prob lems or reviews of current interest in various fields of chemistry. Approxi mately 2 0 N e w York State colleges and universities will b e represented a t t h e meeting. T h e Student Chemical C o l l o q u i m has shown rapid development. As a n oppor t u n i t y for chemical conferences, conducted a n d attended b y undergraduates of t h e -cooperating universities and colleges, t h e movement appears t o fill an urgent need in their academic life. T h e Student Chemical Colloquium was initiated three years ago b y Herbert F . Zuhr a t Union College where the first meeting was held. Subsequent meetings were conducted a t Colgate and Syracuse universities. T h e committee in charge of t h e collo quium this year consists of E . O. Wiig, faculty advisor, F . H . Krenz, chairman, D . E . Kern, F . J. Russell, and W . Kirchgessner.
Vitamin Capsule Machine Developed Louis P . Miller, president of Miller Drug Stores, Inc., and Miller Labora tories, Cleveland, Ohio, and his new vitamin capsule machine. Running at its 24-hour rate, t h e machine can turn out 438,000,000 capsules a year, and supplies· 1,000 companies. Specially prepared gelatin is rolled into soft sheets, cut i n t o accurate lengths, and laid o n a plate precisely cut with 500 round holes, each with t h e diameter of the finished capsule. T h e machine measures a n accurate quantity of carefully assayed vitamin fluid on the sheet, and places over this another gelatin sheet and die plate. A hydraulic press exerts a 40-ton force on the plates for a half minute. The shrinking and hardening of the drying capsules give a perfect seal.
