ASSISTANT CRIEF OF PROTECTIVE D M S I O N (PRINCIPAL CHEMIST). AND FIVE SENIOR CHEMISTS (HEADS OF DMSIONS), TO BE APPOINTED IN CHEMICAL WARFARE SERVICE The United States CivilService Commission states that the positions of assistant chief of protective division (principal chemist) and five senior chemists (heads of divisions), Chemical Warfare Service, Edgewmd Arsenal, Maryland, are vacant, and that in view of the importance of these positions in the field of chemical research the method of competition will be as follows: Instead of the usual form of civil-service examination, the qualifications of candidates will be passed upon by a special board of examiners composed of Dr. A. C. Fieldner, Chief Engineer. Experiment Stations, Bureau of Mines; Dr. J. E. Mills, Chief Chemist and Assistant t o the Technical Director, Edgewood Arsenal; and Dr. A. S. Ernest, Examiner of the U. S. Civil-Service Commission, who will act as chairman of the committee. For the purposes of this examination, all of these men will he examiners of the Civil-Service Commission. The entrance salaries range from 55600 t o $6400 a year for assistant chief of protective division (principal chemist) and from $4600 t o $5200 a year for senior chemists (heads of divisions). Formal applications will be received by the Civil-Service Commission until May 8th. Full information may he obtained by communicating with the United States CivilService Commission, Washington, D. C.
Pearls 25,000,000 Years Old Found in California Rocks. Ten pearl-like fossils found by geologists of the University of California in rocks laid down about 25,000,000 years ago have proved under test t o he real pearls, conforming in structure with the modern variety, and having as their source molluscs related to the present pearl oyster. The pearls were uncovered while the university men were searching for fossils of the Cretaceous period near Redding, Calif. I n spite of their 25,000,000-year burial, from the time when dinosaurs were making their last stand an earth, the pearls still maintain alittle of their luster. Such finds are extremely rare. Some years ago one was reported in England, from the same mollusc and the same period in the earth's history, and one other from the same period has been reported from Texas. I n size the California pearls vary from three-sixteenths to five-sixteenths of an inch in diameter.-Science Senrice
