and can be used, instead of the ordinary 

 gum, with advantage. 



— Mr. T. Charters White* has devised 

 a growing sHde which is cheap and seems 

 to be quite useful. He builds up a cell 

 by cementing strips of thick plate-glass 

 to a slide, which may be of any size de- 

 sired. Then within the cell a piece of the 

 same plate-glass is cemented .in the 

 centre, leaving a space all around it. This 

 space is partly filled with water, and the 

 object to be studied is placed upon the 

 central plate-glass and covered in the 

 usual way. The water in the reservoir 

 prevents the drying of the specimen by 

 evaporation. 



— A writer in The Iiidiana Medical 

 Reporter recommends the following pro- 

 cess for mounting starches. Half a grain 

 of anilin blue is dissolved in an ounce of 

 water and twenty-five drops of alcohol. 

 Equal parts of water and glycerin are 

 mixed, and acetic acid is added in the 

 proportion of two or three drops to the 

 ounce. The glycerin is then colored with 

 the anilin solution. Starches mounted in 

 the blue glycerin retain their natural ap- 

 pearance in a blue field ; the effect is said 

 to be " most beautiful." 



— We take pleasure in calling the at- 

 tention of our readers who are interested 

 in medical science, to Walsh's Retrospect, 

 a Quarterly Compendium of American 

 Medicine and Surgery, published at Wash- 

 ington, D. C. It affords a most excellent 

 epitome of the principal original medical 

 articles published during each quarter ; 

 for this reason, it is one of our most 

 valued medical exchang-es. 



MICROSCOPICAL SOCIETIES. 



CENTRAL NEW YORK. 



A regular meeting of this Club was 

 held on the evening of Tuesday, April 

 26th, at the office of Dr. Aberdein, in Sy- 

 racuse. 



The Secretary read a paper sent by S. 

 A. Webb, Esq., of Oswego, containing an 

 account of some original observations on 

 the mode of reproduction by segmenta- 

 tion of Chilodon ciicullns. 



Dr. W. W. Munson, of Otisco, then 

 gave an informal talk on the anatomy of 

 the flea of the woodchuck, Pulex arcfo- 

 mys. The Doctor began with an expla-

nation of the mouth parts, and followed, 

 through the thorax and abdomen, to the 

 pygidium, illustrating his remarks by 

 slides showing each of the organs, moun- 

 ted in balsam by the carbolic acid pro- 

 cess. The dissection was beautifully 

 done, and was accomplished, for the most 

 part, without the aid of a magnifier. 



ONEIDA CO., N. Y. 



A regular meeting of this Society 

 was held in its rooms Monday evening, 

 April 35th. The President occupied 

 an hour very pleasantly in describing 

 his method of mounting opaque objects, 

 and in describing and commenting upon 

 the Gundlach stands and objectives ex- 

 hibited by Mr. Hodges ; the " physicians' " 

 stand was fitted with Gundlach's new 

 fine adjustment which was greatly ad- 

 mired for its delicate and sensitive motion. 

 Mr. H. C. Maine, of Rochester, was in- 

 vited to attend the May meeting, and 

 speak upon the subject to which he has 

 given so much time and study — diatoms.

OSWEGO, N. Y. 



A Society to be known as the Oswego 

 Microscopical Society has been formed at 

 Oswego, N. Y. President, S. A. Webb ; 

 Vice-Presidents, E. D. MiUiken and E. 

 Burrows, M. D. ; Treasurer, Rev. Father 

 Meagher ; Recording Secretary, Thomas 

 McGinnis ; Corresponding Secretary, Miss 

 Julia B. Douglas. It has already about 

 fifteen members, and fair prospects of 

 doing some good work in the various de- 

 partments of microscopy. 



WELLESLEY COLLEGE, MASS. 



The regular meeting was held Monday 

 evening, April 25th, the Vice-Pre'sident, 

 Miss French, in the chair. 



Professor Nunn gave a very interesting 

 talk on Embryology, the material for 

 which was derived from observations 

 made by her during the summer of 1879, 

 on the Mnemlopsis, an animal of the 

 genus Ctenophore. 



Miss Nunn accompanied her remarks 

 by drawings made on the spot, as the 

 object required. 



Professor Whiting gave a description of 

 the larynx, illustrated by a model, and 

 several experiments in sound. This was 

 to introduce several slides for the micro- 

 scope, illustrating sections of the larynx, 

 showing especially the vocal cords. 



The Society had recently received sev-
