BACTERIOLOGY AND MEDICINE 



The Bureau of Science does a large amount of routine labora- 

 tory work for the Philippine Health Service and others, in- 

 cluding the examination of rats for plague, stool examinations 

 for cholera and other organisms, bacteriological examinations 

 of waters and foods, routine microscopical examinations of blood, 

 urine, faeces, etc. The microscopical work is performed for the 

 purpose of the early identification of infectious diseases such as 

 cholera, bubonic plague, typhoid fever, leprosy, tuberculosis, 

 malaria, worms, genito-urinary diseases, etc. There is a large 

 amount of serum and vaccine work carried on by the Bureau of 

 Science. Serums and vaccines in large variety are continually 

 kept in stock. The entire Islands are dependent upon the serum 

 laboratory of the Bureau of Science for the supply of serums 

 and of vaccine virus. The Bureau of Science produces annually 

 enough vaccine virus to vaccinate 2,000,000 people against small- 

 pox. Wassermann tests to determine the presence or absence of 

 syphilitic infection are performed. A large amount of other 

 work on dysenteries, the activity of drugs and chemicals as a 

 basis for the treatment of various diseases, sanitary surveys, 

 investigation for pathogenic organisms and insects concerned in 

 the transmission of diseases, and many special problems, as 

 shown by the published results in the Philippine Journal of 

 Science, have been completed. The scientists have solved the 

 problems of a large number of tropical diseases with regard 

 to the causes, prevention, and treatment that have baffled spe- 

 cialists all over the world for many years. All this work is 

 ultimately to assist health conditions in the Philippine Islands, 

 and the biological work of the Bureau of Science has been a 

 large factor in successfully combating epidemic and other 

 diseases in the Philippine Islands. 



BOTANICAL AND ZOOLOGICAL SCIENCES 



The botanical and zoological sciences are much alike in that 

 they involve a large amount of routine work in the identifi- 

 cation of species of plants and animals. The naming of species 

 must be done so that the information concerning them can be 

 recorded and correlated with work that may have been done on 

 the same or related species in other countries. 



The work of the botanists involves general work on all phases 

 of Philippine botany. Medicinal and agricultural plants must 

 be studied. Philippine forests contain many species of plants 

 that produce fibers, timbers, gums, resins, dyes, tans, etc., of
