24 '^HE BUREAU OF SCIENCE' 



All of the above problems are being studied in connection with 

 the observations, taken daily at the Manila Observatory, of the 

 intensity of the sunlight, humidity of the atmosphere, amount of 

 rainfall, and the direction and velocity of air currents. 



Apparatus. — Since my last published report we have received 

 considerable new apparatus, the need of which has long been 

 apparent. Among these are a 30,000-pound Olsen testing 

 machine ; a clay-pugging and brick-making machine from Cham- 

 bers Bros. Co.; a Seger furnace; a rotary crusher; jaw crusher; 

 roller cursher ; and sieving machine for grinding and preparing 

 ceramic, cement, road and concrete materials, and ores ; and a 

 19-horsepower liquid-air machine purchased jointly by the 

 Bureau of Science and the University of the Philippines, con- 

 sisting of a 200-atmosphere, 3-step, vertical model compressor 

 with a suction capacity of 54 cubic meters per minute, and an 

 Olszevski apparatus for the liquefaction of air having a capacity 

 of 3 liters per hour. These machines will greatly facilitate the 

 work of this department, but it is desirable that a suitable per- 

 manent place be provided in which to protect them.

DIVISION OF GENERAL, INORGANIC, AND PHYSICAL CHEMISTRY 



Personnel. — Mr. W. C. Reibling, chief of the division, went on 

 leave in April and resigned September 15, 1914, to accept the 

 position of superintendent of the American Tar Products Co., 

 St. Louis, Mo., and Dr. A. P. West was transferred to the Uni- 

 versity on March 18, 1914. Mr. George W. Heise, physical 

 chemist, arrived from the United States and began duty on July 

 24, 1913. Mr. Rutherford B. Martin resigned on November 19, 



1913. Mr. Francisco D. Reyes and Mr. Emilio Natividad severed 

 their connection with the Bureau on April 16 and October 31, 



1914, respectively. Mr. Francisco Peiia was appointed Decem- 

 ber 1, 1913. Mr. R. R. Williams was appointed on September 16, 

 1914, to fill the position of chief of the division. The research 

 M^ork of Mr. Williams has been largely in the field of biological 

 chemistry. The losses suffered by resignation have not been 

 made good, and the present staff is inadequate properly to carry 

 on the work which should be done. 



ROUTINE WORK 



The routine work continues to be of the same general character 

 as that described in the report for the fiscal year 1913. A 

 classified summary of the routine work done by this division by 

 periods since 1909 is included, as follows:
