THIRTEENTH ANNUAL REPORT 5 



superseded by the Journal of Research for printing scientific and technical 

 matter, and by a departmental series of bulletins, written in popular 

 language for selected and general distribution. By this plan the confusion 

 that has resulted from the multiplicity of series of publications will be 

 avoided, and the saving of a considerable sum will annually be ef- 

 fected * * *. 



The highly scientific matter heretofore published indiscriminately in 

 bulletins and cii'culars will hereafter be published only in the newly estab- 

 lished Journal of Research, which will be issued about once a month * * *. 



The Journal will be distributed free to agricultural colleges, technical 

 schools, experiment stations, libraries of large universities and certain 

 government depositories and institutions making suitable exchanges; also 

 to a restricted list of scientific men. Copies of the Journal will be sold 

 to miscellaneous applicants by the superintendent of documents. Govern- 

 ment Printing Office, * * *, 



The new plan of publication work has been designed primarily to im- 

 prove the character of the department's publications, and secondarily to 

 prevent waste in distribution, and through the economies effected, a greater 

 output of information will become possible with the available appropria- 

 tion * * *, 



UTILIZATION OF RESULTS BY THE BUREAU OF HEALTH 



A noteworthy thing in the Annual Report of the Director of 

 Health of the Philippine Islands for the fiscal year ending June 

 30, 1913, is the record of the extent to which the results of 

 work of the Bureau of Science have been utilized by the Bureau 

 of Health. The following instances quoted from my memoran- 

 dum report of December 31, 1913, indicate the extent to which 

 the routine work and researches of the Bureau of Science have 

 contributed to the improved health conditions of the Islands, and 

 show a few of the ways in which this work has been put into 

 practical use. 



A pamphlet entitled Insects and Diseases is used in public schools and 

 will, no doubt, do much good in disseminating such information as that 

 malarial fever is conveyed by definite kinds of mosquitoes, that filariasis 

 is transmitted by another, etc. During the fiscal year 1913 the Bureau 

 of Science examined 23,450 samples of blood for malarial parasites and 

 similar organisms, and during the last six months the scope of this work 

 has been extended. 



The Bureau of Health circular formerly issued on dysentery has been 

 revised and rewritten, and its provisions now correspond with the more 

 recent study made by the Bureau of Science in the prevention of this 

 disease. The work of Doctor Walker of this Bureau upon amoebic dysentery 

 is epoch making. Another pamphlet was prepared on beriberi which has 

 awakened the public to the fact that beriberi occurs among those who 

 use polished rice as a staple article of diet. The work of Doctors Strong 

 and Crowell and of Mr. Williams, of the Bureau of Science, and of others, 

 including the United States Army Board for the study of Tropical Diseases 

 as They Exist in the Philippine Islands, here manifests itself. An illus- 

 trated pamphlet on The poisonous fishes of the Philippines, which has
