SIR: By act of the United States Philippine Commission, the Bureau of Government Laboratories will in the 
future include not only the divisions of scientific work which heretofore have been comprised in it but also the former 
Mining Bureau of the Philippine Government, and the united institutions will be known as the Bureau of Science. 
Beginning with January 1, 1906, it is proposed to change the form of the publications which in the past have 
appeared as the “Bulletins of the Bureau of Government Laboratories” to a journal which will be known as the 
PHILIPPINE JOURNAL OF SCIENCE. This publication will include original articles by the members of the 
staff of the Bureau of Science as well as scientific papers submitted for publication by other officials of this Govern¬ 
ment and by individuals who are not officials. The subjects covered by the organization of the Bureau and which 
will find a place in the new journal will be: Researches on biological subjects, including bacteriology, pathology, and 
allied branches of the science relating to medicine, botany, and zoology; on chemistry, including topics relating to the 
natural products of the Islands, to analytical and synthetical work, and to physiological and biological chemistry, 
researches relating to the field of serums and prophylactics and on mineralogy, geology, and paleontology, including 
investigations of the mineral resources and mining operations of the Philippines. 
The scope of this journal will be varied and, covering as it does the field of scientific work in the Philippine Islands, 
it will be a publication which will give a review of the work which is being accomplished and of the original results 
which are being obtained. Readers who wish to follow special topics only can obtain author’s reprints, but it is hoped 
that many workers in the scientific field will be sufficiently interested in all of the advances which are being made in 
this most interesting tropical country to subscribe for the complete journal. 
The JOURNAL will be issued in as many numbers as may be necessary during the year, with a probable 
minimum number of ten, so that it will appear approximately once a month. The subscription price has been placed 
at $5, United States currency, per year, payable in advance; single numbers at 75 cents, United States currency, 
reprints at 25 cents, United States currency, per number. Where a reprint includes serial portions contained in several 
numbers, the entire article, bound together, can be had at one-third the total cost of the numbers of the journal involved. 
The first number will appear on or about January 1, 1906. ALL REMITTANCES TO BE SENT TO 
THE DIRECTOR OF PRINTING, MANILA, P. I. 
1 am, very respectfully, 
Director of the Bureau of Science.
