1894J NEW-YORK MICROSCOPICAL SOCIETY. 41 



several original substances here shown, and the results when these 

 are made into pulp and paper, as I have already described/ 



I regret that I am unable to throw more light upon what we 

 have discovered to be an intricate and vexatious subject; but if 

 no further advantage shall be attained from our earnest efforts at 

 this time, I hope, at least, that other members will be induced tO' 

 take up not only the further investigation of paper admixtures, 

 but also the analysis of many of the familiar products manu- 

 factured and in common use, with a view of making known to 

 the world what adulterations they severally contain. 



Moreover, I have chosen a utilitarian theme on this occasion 

 whereby the microscope is applied to the economic arts; may I 

 be pardoned, therefore, for the lack of truly scientific work which 

 might be expected in an annual address before such an association 

 as ours ? If no other benefit shall result therefrom, we as micro- 

 scopists, when engaged in kindred lines of research where science 

 is applied to the practical arts, may perhaps disprove the imputa- 

 tion that we can claim no independent position in either the arts 

 or sciences. 



1 Of the numerous photomicrographs made by Dr. Love, we have had portioriF, two 

 inches square, cut from eleven of them, and reproduced in half-tone by the photo- 

 engraving process, and inserted in this publication in two plaief.
