After the death of Schutzenberger his friends and colleagues caused a marble bust of him to be made and presented it to the Ecde municiflal? de @hysiqueet de chimie de la Ville de Paris of which he had been director. The bust, "made with much talent by G. Urbain, a former student a t the school," and, as Friedel said, " a w s i bon clzimiste que statunire, reproduces in a striking manner, although made after the death of its model, his characteristics and his expression, at once serious and gentle, fine, and animated, the artist baving only to make an appeal to his memory and to reproduce what he had seen ,a hundred times in the lectures at which he had assisted." Urbain has since become most distinguished for his work on the rare earths. As president of the Sociiti chimique de France he spoke a t Strasbourg in July, 1928, on the occasion of the inauguration of a bronze memorial tablet of Schutzenberger in the chemistry amphitheater of the University. He designed the plaquette which is to be used in connection with the celebration a t Paris next December.

Pyrites Production in Spain. Production 4f. copper and iron pyrites in Spain during the past three years has averaged approximately 3,620,000 metric tons. The 1926 production was 3,650,390 tons; 1927. 3,602,870 tons; and 11 months of 1928, 3,606,710 tons.-Chem. Age, 20, 554 (June 8. 1929).
Lower Cast for Acetate Films. In about a year the cost of photographic film with cellulose acetate base, now about one-fifth higher than the dangerous cellulose nitrate film that caused the Cleveland Clinic disaster, may be reduced so that it competes in price with the nitrocellulose variety. This is the prediction of chemists who foresee future price declines in the costs of the raw materials, acetic anhydride and acetic acid. that enter into the manufacture of the cellulose acetate film base. New methods of manufacture of acetic acid and its compounds from alcohol are likely t o bring about a price reduction of acetic acid from about 14 cents t o 8 cents a pound. Higher cost of the acetate films has been one of the chief factors in t h e continued use of the explosive cellulose nitrate films for x-ray use in hospitals despite the acknowledged danger that large quantities of such films entail. Lawer cost for acetate films is expected to speed their use and reduce the hazards of storage of all sorts of films, whether in hospitals or elsewhere. Laws and regulations are likely t o require in the near future that the use of the safe acetate films shall be extended to ordinary photographic negatives, commercid motion picture fdm, etc. The 16 mm. or reduced size film is already manufactured only on safety stock.-Science Senice
