THE BUREAU OF SCIENCE 



the demands on the division and to place the work under three 

 superintendents of sections who would report directly to me, as 

 follows : 



1. Section of analytical chemistry: 



Messrs. T. Dar Juan, A. S. Argiielles, F. D. Reyes, F. Pefia, and 

 G. Rantaso. 



2. Section of weights, measures, water analysis, and physical chemistry: 



Messrs. G. W. Heise, V. Q. Gana, R. H. Aguilar, and E. Ignacio. 



3. Section of physical and mechanical testing: 



Dr. J. C. Witt and Messrs. A. E. W. King and F. R. Ycasiano. 



The work of the various sections, as specified in my memoran- 

 dum order, is as follows: 



Section of analytical chemistry: 



Rocks, minerals, ores, slags, clays, limes; plasters, soils, fertilizers, etc.; 

 iron and steel; metals and alloys; pigments and mixed paints, in- 

 cluding vehicles; fuels, including calorific value; gas; and inorganic 

 chemicals and other inorganic analyses, except fire assays. 

 Section of weights, measures, water analysis, and physical chemistry: 



Waters, sewage, corrosion; weights and measures; and instruments and 

 apparatus such as thermometers, pyrometers, microscopes, refrac- 

 tometers, and other physical and chemical apparatus. 

 Section of physical and mechanical testing : 



Cements, aggregates; iron and steel; road materials; tars, asphalts, and 

 bitumens; stones, twines, ropes, wires, khaki cloths, fuels, etc.; and 

 the standardization of other classes of supplies.

 general, inorganic, and physical chemistrj'- is shown in the fol- 

 lowing classified summary :
