will need. With it he may do all that he may wish. It wilf 

 give him as high a power as he need desire, since it will show 

 him all that a higher could show, and do it better. With these 

 four splendid objectives the reader will be the microscopical peer 

 of microscopical workers, of course excepting the bacteriologists 

 that demand powers even higher than the ^ . He will never 

 need any others, unless he is able to possess luxuries, with which, 

 this little note has nothing to do. 



Let me once more repeat. If you cannot take these four at 

 one time, take one at a time, and begin with the one-inch. That 

 will do commenable service, and will last the microscopist his 

 life. He will never feel the least inclination to change it. And 

 his feelings toward the others wdll be exactly the same. With, 

 these four he should be happy. 



DR EDWARD GRAY, Benicia, Cal., has recently taken the- 

 agency for Reichart's admirable objectives. These lenses 

 are praiseworthy in every respect, as I know, having just had the 

 satisfaction of examining the homogenous ]V referred to in this 

 Department for June last. A note from England says that 

 Reichart has recently made a pocket-lens that seems to be su- 

 perior to anything of the kind that British microscopists have 

 heretofore seen. 



I am also glad to announce that Miss M. A. Booth, Long- 

 meadow, Mass., has taken the agency for Thum's arranged ob- 

 jects. These are magnificent things, and the low price is in no^ 

 way comparable with their excellence.
