SEPTEMBER 10, 1939 amide and vitamin Bi are also shown, and a notice calls attention to the sulfur cement used as a binder for the tile floor. Johne-Manville, with the help of motion pictures and murale, explains now indus trial products are made from asbestos, as phalt, diatainaceous earth, and limestone. At the Sealtest Building, chemists in an air-conditioned, glass-partitioned labo ratory perform simple routine milk tests. Production units for the manufacture of ice cream, for cream cheese, and for bottling cream and milk round out an interesting exhibit on modern dairy prod uct technique. The Standard Brands Building con tains a modern vitamin laboratory which features a new technique of vitamin analysis baaed on the evolution of carbon dioxide from flasks of fermenting vitaminsugar mixtures. On display are crystal line samples of vitamins A, B, D, and G. A light glare test for automobile drivers detects vitamin A deficiency by noting the time required for the eye to distinguish objects after exposure to light glare. The United States Steel Co. suspends a grand piano on a single piano wire and explains modern steel manufacture with dioramas of an ore mine, blast furnace, open hearth, and blooming mill. Physical tests of steel, such as hardness and elas ticity, are demonstrated in the Hall of Research. Routine distillery tests and experi ments are performed in a well-labeled chemical laboratory in the Distilled Spirits Building. A large rotating helix, with miniature farms and factories, pictures the products and amounts of raw materials used every year by the distilled spirits industry. Looking upward toward the peak of the helix, the evolution of the raw material t o the finished product is re vealed. Animated murals with a moving belt of little gnomes illustrate the chemical changes which take place when corn, etc., is converted into alcohol. The chemist at the New York World's Fair will find much more of interest than can be printed in this account. At the glass center, crowds, enchanted with the mechanical perfection of the machines producing Fibergias, move on, only to envy the artistic skill of masters practicing an ancient art—that of glass blowing. Eastman Kodak Co. explains photo graphic film manufacture and the changes brought about by exposure. Goodrich demonstrates the manufac ture of Koroseal and displays uses of Flexlock, a flexible pipe joint. In the Metals Building Timkin rollerbearing has a museum of bearings; Yale and Towne Co. show how materials are handled with modern loading and stacking trucks; and link-Belt shows moving models of link belts and chains against a background of illuminated color murals of industrial applications of belts. The Edward G. Budd Mfg. Co., whose forte would appear to be the manufacture of light weight, streamlined, railway cars, displays a glass-enclosed working cuprammonium rayon unit. The Metals Building has a vivid display of copper through the ages. Dioramas trace the use and manufacture of copper from the cave man to modern coppermining operations. There is a large three-dimensional model of a copper atom, enlarged 20,000,000,000 times. I t failed to impress one lady visitor who was evidently worried about future genera tions. "Only 20,000,000,000". she said, indicating the atomic model, "why that's only half as large as our national debt".

Eighth National Organic Chemistry Symposium St. Louis, Mo·, December 2 8 to 3 0 , 1 9 3 9 Preliminary A n n o u n c e m e n t HB St. Louis Section of the AMERICAN T CHEMICAL SOCIETY will act aa hosts to organic chemists at the Eighth National
Organic Chemistry Symposium. The meetings are to be held in the auditorium of St. Louis University. The sessions will start Thursday morning, December 28, and end Saturday noon, December 30. The program will provide a wide variety of topics. Although the list of speakers is not quite complete, the following chemists have agreed to address the symposium: Roger Adams, A. H. Blatt, F. F. Blicke, A. C. Cope, E. A. Dotsey, Louis F. Fieser, Henry Gilman, Harold Hibbert, John R. Johnson, W. M. Lauer, Randolph T. Major, Rudolph Schoenheimer, Lee I. Smith, and Wm. G. Young. Attendance at the Organic Symposia has increased to such an extent that difficulty has been experienced in providing means and facilities for the discussion of papers. At the St. Louis Symposium plane are be ing made for separate discussion rooms for each speaker. Each speaker of the day will be assigned to a room between 4:45 p. M. and 5:30 P. M. At that time all who are especially interested may go to the room designated, ask questions, and dis cuss the topic presented. No open dis cussion will take place at the time of the lectures. The custom of printing in the program the material presented by the speakers on their slides met with such general approval at Richmond that it is planned to repeat this feature at St. Louis. These special programs will be available at the time of registration only, upon payment of the registration fee of $1.50 for members of the AMERICAN CHEMICAL SOCIETY and regu
larly matriculated students. Registration fee for chemists not members of the AMERICAN
CHEMICAL SOCIETY
will
$3.00. The committees in charge follow: GENERAL COMMITTEE.

everyone planning to attend the sym posium make a reservation. No special railroad rates or certificates will be available. However, manv rail roads and bus lines have special Christmas and New Year round-trip rates and mem bers should consult their local ticket agents. The complete program, with titles of the talks, will be published in the November 10 NEWS EDITION.
The Executive Committee of the Divi sion of Organic Chemistry cordially invites all chemists interested to attend the sym posium, whether or not they are members of the division. RALPH L. SHRINBB
Secretary, Division of Organic Chemistry By-Product Sulfuric Acid a t Copper a n d Zinc Plants HE output of by-product sulfuric acid T at copper and zinc plants in 1938, in terms of 60° Be. acid, amounted to 687,176
short tons, of which 220,297 tons were produced at copper plants and 466,879 tons at zinc plants, according t o the Bureau of Mines, United States Depart ment of the Interior. The acid reported is only that produced from the sulfur content of the sulfide ores. The figures are exclusive of acid made from pyrites concentrates in Montana and Tennessee. Some acid recovered as a by-product in the roasting of high sulfide gold and silver concentrates is included in the tonnages for copper plants for 1938 and 1937, and is included in this manner in order to avoid the disclosure of confidential information. In addition to the quantities given above, 30,996 tons of sulfuric acid were made at zinc plants from 8248 tons of sulfur, indi cating a large decline in the use of sulfur for boosting the recovery of acid at zinc plants. No sulfur was used at copper plants.

N e w T e l e p h o n e Laboratory HE American Telephone & Telegraph T Co. has announced that it will build a new laboratory at Murray Hill, N. J., at a cost of $3.000,000. The 200-acre site was purchased for this purpose 10 years ago. The laboratory is expected to be completed in 1941 and to house about 800 workers.
