EXPLANATORY NOTE ON THE SPECIMENS OF PAPER INSERTED IN THIS ARTICLE. 
In response to numerous requests for specimens of paper made from the raw 
materials investigated, we have inserted into this number of the JoURNAL samples 
of handmade paper from abac&é waste and cogon grass. Similar specimen sheets 
made from banana, bamboo, palms, and other material will be sent on request. 
It was thought best not to alter the pulp in any way, but only to- provide pure 
bleached specimens, thus affording paper manufacturers and others who are 
interested an opportunity for testing the fiber to their own satisfaction. Conse- 
quently, no attempt at loading, sizing, coloring, or calendering the specimens was 
made. The work required to turn out several reams of handmade paper with 
apparatus available in the laboratory is very great, and it was practically all 
performed by Filipinos. This speaks favorably for their skill in acquiring facility 
in manipulations of this kind. 
In a future paper other Philippine paper materials will be discussed, 
and data in regard to the available supply of all raw materials, so far as 
such data can be obtained, will be given.
