You do not want to wait an hour t o filter an iron hydroxide precipitate which you intend t o ignite and weigh. Use W H A T M A N F I L T E R P A P E R Number 41 and you will save much valuable time. Number 41 has been washed with Hydrochloric and Hydrofluoric Acids—the ash weight is negligible. I t filters very rapidly, yet is firm enough t o be washed without pulping.

Cornell to Give Summer Course in Chemical Microscopy I n addition to the courses regularly given, the Department of Chemistry of Cornell University this year is offering courses in chemical microscopy as a part of the curriculum of the summer session. The facilities for work in chemical microscopy in the new Baker Laboratory of Chemistry are unsurpassed, and this opportunity to get in touch with methods which are applicable to a great variety of problems in research and testing should a t tract a number of chemists. A general course in the applications of the microscope to chemistry, and another covering the field of microscopic inorganic qualitative analysis, both of which will be the full equivalent of those given in the regular college year, are t o be scheduled. These may be taken separately or together, or in conjunction with other courses in the summer session. Chemists not desiring university credit may arrange to cover only such portions of the work as are most suited to their needs, and thus obtain the essential training in a minimum period of time. Dr. C. W. Mason, who has handled the regular courses during the absence of Professor E. M. Chamot, will have charge of the work in the summer session, and any inquiries regarding it should be addressed to him a t the Baker Laboratory, Ithaca, N . Y.
Washburn Addresses Baltimore Section A t the meeting of the Baltimore Section of the American Chemical Society held in the Chemical Laboratory, Johns Hopkins University, Homewood, Baltimore, Md., February 27, 1925, Dr. E. W. Washburn of Washington spoke on "Work o n the International Physical and Chemical Tables." Dr. Washburn showed various troubles he had run into in interpreting the results of the various investigators. He pointed out the various methods used in determining the accuracy of results and also the methods used in comparing results, in order to obtain more nearly accurate values. H e cited as examples, a critical review of t h e values of the vapor pressure of ice and supercooled water. H e also showed the effect of not correcting weights t o vacuo. Dr. Robert Calvert of the University of Maryland also spoke at t h e same meeting o n automobile lacquers, giving a description of the various raw materials, cottons, resins, and solvents; also the manufacture of the raw materials and the compounding of t h e lacquer. He showed various samples of raw materials, intermediate products, final products and applied lacquers o n wood and metal. T h e meeting was preceded by a dinner at the Engineers' Club, Light & Redwood Streets. About forty attended the dinner and about 150 attended the meeting.
Hypochlorites as Poultry Disinfectants A . E. Gibbs of the Research Department of the Pennsylvania Salt Manufacturing Co., calls attention to the value of calcium or sodium hypochlorite as a disinfectant for hen houses and yards. He states that this material has been used for many years for this purpose throughout the United Kingdom. I t is sold in the form of a solution containing ten per cent of available chlorine. Two tablespoonfuls of such solution i s diluted with one gallon of water and sprayed onto the infected houses. This disinfectant is claimed to be more powerful than carbolic acid or formaldehyde, nonpoisonous and practically odorless.

T h e Czecho-Slovak Chemical Industry now embraces 18 factories manufacturing soap, candles, and glycerol, and 18 manufacturing vegetable oils, varnishes, and lacs (especially colza, oil). The nine petroleum refineries work up Galician and Roumanian naphtha to the extent of about 33,000 tanks per annum. The maximum home production is estimated at 20,000 tanks. D r y wood distillation is conducted in eight establishments, using 200,000 cubic meters of wood every year, from which they make charcoal, calcium acetate, methyl alcohol, and wood tar. Coal-tar is distilled in 84 establishments.—Chemical Age (London).
Hebrew University to Build Research Laboratory Plans for the Hebrew University on Mt. Scopus, Jerusalem, include 4,000 pounds for the year 1924-1925 for a chemical institute and a proposal of buildings for microbiological and chemical research to cost 40,000 pounds. The chemical department is in charge of Professor Fodor, formerly of the University of Halle. The university is a part of the work of the Zionist Commission.
