— We have received a few excellent 

 mounts of late which deserve to be men- 

 tioned in this place. From Miss M. A. 

 Booth we have a dry mount of scales 

 from a mosquito which are so evenly dis- 

 tributed over the field that we are tempted 

 to ask her how it was done, and to re- 

 quest an answer for the benefit of our 

 readers. She has also favored us with a 

 fine preparation of Tabcllaria flocculosa, 

 a common diatom, but a good one to 

 mount. 



Mr. E. G. Day has sent us some speci- 

 mens of the preparations he has been 

 offering for sale in our advertising col- 

 umns. They arc well mounted, and 

 doubtless many of our readers have al- 

 ready obtained some of them. 



From the histological laboratory of the 

 University of Pennsylvania we have re- 

 ceived sections of the lung of an ox, and 

 of the mammary gland of a cat, and trans- 

 verse sections of a dog's lip, and of human 

 sciatic nerve. The preparer's name was 

 not given on these. 



— In an interesting communication to 

 Zooloqischer Anseiger, Lud. Plate de- 

 scribes some features in the structure of 

 the rotatoria, particularly the genital or- 

 gans and nervous system, and the pro- 

 cess of fertilization. In closing, the au- 

 thor remarks that the assertion that roti- 

 fers can withstand dessication is not true, 

 and states that many of them die in a 

 short time when they come in contact 

 with the air on the surface of the water. 



— Mr. W. H. Bulloch informs us that 

 he is constructing a microtome for cutting 

 sections in ribbons, which shall embody 

 the best features of the various foreign 

 instruments in use and some of his own 

 devising in addition. Mr. Bulloch's well- 

 known ingenuity will no doubt enable 

 him to produce a microtome that will be, 

 as he hopes, superior to all others. 



— We have received an unusually ex- 

 cellent photograph of members of the 

 American Society of Microscopists taken 

 in a group at Rochester, by Messrs. Bow- 

 dish and Hoagland, of that city. The 

 price of the prints, mounted on cards 20 

 by 24 inches, with a ' key ' which gives 

 the name of each person in the group, is 

 .S2.00; unmounted prints are j? 1.7 5 each. 

 This is a very interesting card for micro- 

 scopists, as the portraits are all good, and 

 many of them are of persons known fv^ell 

 by name to every microscopist. 



— The next meeting of the American 

 Society of Microscopists will be held in 



Cleveland, Ohio, by invitation. The 

 microscopists of that city will endeavor 

 to make the meeting pleasant and in every 

 way successful. They have ample time 

 for preparation. 



— We learn that Dr. Sternberg is hav- 

 ing some enlargements of his photomi- 

 crographs of bacteria for the New Orleans 

 Exposition, which opens in December. 

 The enlargements are being made at the 

 Army Medical Museum. It is a severe 

 test of a negative to produce large pic- 

 tures from it, and we should hesitate very 

 much about subjecting a negative from 

 such difficult specimens to represent by 

 photography as Dr. Sternberg has studied 

 to such a process. We trust, however, 

 that the results will prove creditable to 

 him, who is deserving of much credit for 

 his painstaking work. 



— The Baltimore Microscopical Society 

 seems to be in a flourishing condition. 

 Its meetings are now held at the Johns 

 Hopkins University, and Dr. Councilman 

 has been elected president for the current 

 year. Among the members are a num- 

 ber of well-known microscopists, Dr. G. 

 M. Sternberg, who is conducting his re- 

 searches in the university laboratory, Dr. 

 L. M. Eastman, whose extensive calainet 

 of slides is already famous, and others of 

 whom we shall doubtless hear from time 

 to time through their contributions to 

 these pages.* 



— It is surprising to notice the extremely 

 low price at which books are now pub- 

 lished, dependent, to be sure, upon a very 

 large demand. From a circular of John 

 B. Alden, of 303 Pearl street. New York, 

 author of the ' literary revolution ' which 

 attracted much attention about three years 

 ago, we learn that the work of publishing 

 cheap editions of valuable works still 

 continues. A monthly magazine. The 

 Book-Worm, is published for 25 cents a 

 year, which is full of interesting reading; 

 another monthly. Choke Literature, much 

 larger and more solid in the character of 

 its reading matter, is ^i.oo a year. As for 

 books, Guizot's ' Mistory of France' is 

 sold in 8 small octavo volumes for $j.oo, 

 with 426 full-page illustrations. This 

 work, in its original form, was sold at 

 $50.00. Rawlinson's 'Seven (ireat Mon- 

 archies of the Ancient Eastern World ' is 

 offered for #2.75. A catalogue of 100 

 pages will be sent to any applicant, and 

 those who are not acquainted with the 

 ' literary revolution ' will do well to look 

 over the catalogue.
