In addition to the strictly Micro- 

 scopical Societies there are several 

 associations having microscopical sec- 

 tions, or which give occasionally mi- 

 croscopical exhibitions. We have 

 before us programmes of the micro- 

 scopical soiree of the Purdue Scien- 

 tific Society, Lafayette, Ind., given 

 in June, 1885, and also of the Port- 

 land Society of Natural History, Port- 

 land, Me., given in April. 



NOTES. 



— We are indebted to the Palmer Slide 

 Company, whose advertisement is to be 

 found on another page, for a number of 

 samples of their bevel-edge slides, but 

 recently introduced. These slips are cer- 

 tainly very attractive in appearance, and 

 are well adapted for ornamental prepara- 

 tions. Some are plain glass, very color- 

 less and free from defects, others are 

 flashed with a color on the under surface, 

 which modifies the light, or adapts them 

 very well for opaque mounting. The 

 only cridcism we would make of these 

 slides is, that we anticipate careless hand- 

 ling will result in chipped corners. The 

 company also manufactures plain slides 

 ot the ordinary kind, but of a superior 

 quality of glass, at very reasonable prices. 



— Mr. Woolman has been sending out 

 a circular and a preparation mounted on 



the new bevel-edge slide to'illustrate the 

 beauty of the mounts on such slips. Mr. 

 Woolman, in further recommendation of 

 the slips, says : ' Aside from the great 

 beauty of the finished object, making 

 them the most elegant slide yet intro- 

 duced, their bevel-edge allows them to 

 glide smoothly under spring clips on the 

 stage of the microscope. They are made 

 of Chance's crystal plate and Chance's 

 flat crown, and with ground edges, or 

 ground and polished edges.' They vary 

 in price from $4.00 to $6.00 per gross. 



— Dr. Otto A. Wall has recently as- 

 sumed charge of the microscopical col- 

 umns of the National Druggist, of which 

 he is associate editor, and has begun a 

 series of articles on the microscopical ex- 

 amination of drugs, which promise to be 

 very useful to pharmacists. The editor 

 of the Druggist, H. M. Whelpley, Ph. 

 G., is also instructor in the microscopi- 

 cal laboratory of the St. Louis College 

 of Pharmacy. The laboratory is well 

 equipped with microscopes and apparatus, 

 as we learn from the Prospectus of the col- 

 lege, and claims to offer the best facilities 

 for instruction in the West. 



— Thirty-two parts of ' Our Living 

 World,' an artistic edition of the Rev. 

 J. G. Wood's Natural History of Animate 

 Creation, already noticed in these col- 

 umns, have been issued, leaving only ten 

 more parts to complete the work. There 

 is no illustrated popular natural history 

 that equals this, in the interest of the 

 text or the excellence of the illustrations, 

 all of which are accurate. The wood-cuts 

 are well executed and numerous, mostly 

 taken from living animals, but the colored 

 plates are especially fine; for example, 

 the group of young leopards and mother — 

 but they are all worthy of praise, and some 

 of the birds are particularly good. For a 

 popular natural history, this is far better 

 than any systemadc work on the subject. 

 The classification of animals has not been 

 disregarded, but this has been made sub- 

 ordinate to the descriptions of the animals 

 themselves, their appearance, habits, and 

 distribution. The publisher is Selmar 

 Hess, New York city. 



— A form of cobweb micrometer has 

 been introduced by Mr. Bulloch, which is 

 certainly one of the best we have seen. 

 The workmanship of it is first-class, leav- 

 ing nothing to be desired in that respect. 

 In addition to the movement of one set 

 of lines with the micrometer screw, an- 

 other screw, worked with a milled head 

 on the other side of the instrument, moves
