THE AMERICAN MONTHLY 



[August, 



directions will be given of the manner in 

 which drawings can be made from the 

 Microscope. Each section of the work 

 will be fully illustrated with drawings 

 and diagrams. The chapter on Micro- 

 scopical Art, will include a sketch of the 

 ways by means of which drawings may 

 be reproduced, such as by photography, 

 lithography, etc., and will be accompa- 

 nied by suitable plates as illustrative 

 examples. This work is complete in 

 itself, and is to be issued weekly, begin- 

 ning in June. The subscription price 

 will be about $1.50. 



Two sections of the second volume of 

 the " Studies " have been announced for 

 publication on July 7th, the sections of 

 animal and vegetable histology respec- 

 tively. These sections will be issued in 

 monthly parts, the subscription-price of 

 each being about $6.00 for the year. The 

 third section will begin on July 14th, and 

 be devoted to a series of popular objects, 

 illustrated by slides and lithograph-plates, 

 like the others. The subscription-price 

 will be the same as for the others. We 

 are unable to give the prices more defi- 

 nitely, as we are not informed of the pos- 

 tal charges. 



— J. B. Schnitzler has observed the 

 growth of a confervoid alga from a spe- 

 cies of Palmella. In a rivulet near Lau- 

 sanne he observed some bright-green 

 cells enveloped in a gelatinous matrix, 

 which he determined to be Palmella 

 uvceformis Ktz., the cells being about 

 o.oi mm. in diameter. These were 

 placed in a glass with water, and covered 

 with a watch-glass. In two days swarm- 

 spores were formed which attached them- 

 selves to the sides of the vessel and ger- 

 minated, forming branched filaments. 

 From these filaments in turn, were again 

 produced gelatinous colonies of Pah/iella, 

 by the breaking up of the filaments into 

 spherical cells with gelatinous coats. 



— The American Society of Microscop- 

 ists have finished their session for 1883 

 at Chicago, and we regret that we have 

 not received any report of the proceed- 

 ings in time to publish them in this is- 

 sue ; but next month we hope to give our 

 readers a full account of the sayings and 

 doings of the Society, and also a report 

 from the Minneapolis meeting of the 

 A. A.A.S. 



— We have received from the author, 

 C. F. Millspaugh, M. D., a specimen sheet 

 of a new work now being published by 

 Messrs. Boericke and Tafel, entitled 



A/jterican Medicinal Plants. It is to be 

 completed in thirty monthly parts con- 

 taining six plates with text each. 



The work is quarto size, handsomely 

 printed and the Plates are all that could 

 be desired. We bespeak for it an ex- 

 tensive sale. 



CORRESPONDENCE. 



To THE Editor: 



Dear Sir: — The Cleveland Micro- 

 scopical Society at a special meeting held 

 July 24th, 1883, adopted memorial resolu- 

 tions, a copy of which 1 enclose, with re- 

 spect to the late Dr. W. B. Rezner, Presi- 

 dent of said Society, and instructed me 

 to forward a copy to the American 

 Monthly Microscopical Journal 

 with request that the same be published. 

 I am respectfully.

" As members of the Cleveland Micro- 

 scopical Society, we are called to mourn 

 the loss of Dr. William B. Rezner, our 

 president. He was one of the original 

 promoters and most ardent supporters of 

 our organization, and our first president, 

 and we realize that in his loss one of our 

 brightest lights is extinguished. For up- 

 wards of twenty years he had devoted 

 attention to microscopical studies, and 

 brought to his aid not only ripe scientific 

 acquirements, but a rare inventive genius 

 and an unexcelled mechanical skill. In 

 his scientific studies and methods he was 

 cautious and painstaking, and one of his 

 most distinguishing characteristics was 

 his indomitable perseverance in following 

 out an idea to its result, and learning the 

 actual and ultimate truth to which it 

 related. In such pursuits no obstacle 

 was sufficient to deter or discourage him. 

 Unaided and uninstructed he met and 

 overcame innumerable obstacles in his 

 favorite pursuit, by his acute inventive 

 genius and his manipulative skill, and the 

 amount of labor he has spent in the deter- 

 mination of difiicult questions which have 

 arisen in the course of his investigation, 

 can never be fully known, although it is 

 known to many of his friends to be enor- 

 mous. 



"When, many years ago, in the earnest 

 study of microscopy, the resolution of 

 difficult tests attracted his attention, he 

 devoted much time to that subject, and 

 with the most untiring patience worked
