TWELFTH ANNUAL REPORT 45 



assistant in the biological laboratory, and assumed his duties 

 November 11, 1912. Mr. Lyle D. McMillan was transferred 

 from the Bureau of Education to the biological laboratory of 

 this Bureau June 5, 1913. Three assistants in the routine lab- 

 oratory have left during the year and have been replaced by 

 other men. The position of chief of the biological laboratory 

 and a few other vacancies remain unfilled. 



All of the instruction in medical zoology in the College of Medi- 

 cine and Surgery and in the Graduate School of Tropical Medi- 

 cine and Public Health of the University of the Philippines is 

 given by members of the staff of the biological laboratory of the 

 Bureau of Science. The courses given in the undergraduate 

 school of medicine include — 



1. A course in protozoology, occupying 3 hours a week during the second 

 semester. 



2. A course in helminthology, occupying 9 hours a week during the first 

 semester. 



3. A course in medical entomology, occupying 2 hours a week during the 

 first semester. 



In the Graduate School of Tropical Medicine and Public Health, 

 the courses in protozoology and helminthology will occupy in 

 the class room and laboratory at least 12 hours a week through- 

 out the year, and the course in medical entomology at least 24 

 hours a week for six weeks, exclusive of the preparation of 

 lectures and of material for laboratory work which requires 

 at least as much more time. 



ROUTINE WORK 



The routine work is constantly increasing and occupies more 

 and more of the available staff of this laboratory. It showed 

 an increase in 1912 of 45 per cent above that of the year 

 before, and there has been a still greater increase during the 

 past year, as shown by the table on page 46. Branch labo- 

 ratories are still maintained at the Philippine General Hospital 

 and at Bilibid Prison Hospital to handle the large amount of clini- 

 cal laboratory work at these institutions. An assistant from the 

 laboratory has been detailed to make bacteriological examina- 

 tions on each trip of the Bureau of Health to collect lepers. 



The following table shows the number of routine examinations 

 made during the past, and, for comparison, during the preceding 

 fiscal year. The classification of these examinations for the 

 year of 1912 was less exact, many of the samples classified in 

 this table being put under miscellaneous. This accounts for 

 the blank spaces in the 1912 column.
