draw attention to the analogy existing between the results ob- 

 tained by Dr. Bleile on the lung of the salamander so far as his 

 investigations go, with those here given. 



Finally, I wish to hazard the opinion that the method of 

 preparation here given will be found of value, as I believe 

 nervous tissue can in this manner be differentiated in any of

THE WORKING SESSION. 



A WORD TO THE WORKING MICROSCOPISTS. 

 BY C. M. VORCE, CLEVELAND, OHIO. 



THE preparations for the Eighth Annual Meeting of the 

 American Society of Microscopists, to be held in this city Aug. 

 18-21, 1885, are well under way, and will be, it is hoped, very 

 complete. The labor of these preparations has fallen largely to 

 my share, and with the general work, that of the Soiree and the 

 Working Session added to my regular professional work, will 

 make my own personal " working session " cover a continuous 

 period of three months, almost night and day. Foreseeing this, 

 to some extent, I published in The Microscope for February, 

 1885, the scheme of work adopted, and the cooperation of the 

 working microscopists of the country in carrying it out. In 

 that communication I solicited offers of aid in the Working 

 Session, but to my sorrow I am compelled to say that my appeal 

 seems to have fallen upon heedless or indifferent ears, for to 

 this time I have not received a single offer of assistance in re- 

 sponse to that call ! 



" Call you this backing your friends ? " 



In response to personal letters a goodly number of expert 

 demonstrators have been secured for the Working Session, but 

 some subjects of the scheme of work still remain unfilled, and 

 there is ample opportunity for the further illustration of the 

 subjects assigned by means of different methods, new apparatus, 

 new processes, etc. It will be impossible for me to take the 

 necessary time to write directly to all those whose services in 

 the Working Session I wish to secure, and therefore I now repeat 

 my appeal to all microscopists who are willing to serve their 

 society and their fellow members, and be of benefit to the cause
