178 THE MICROSCOPE. 



friends for their kind criticisms and suggestions. We know we have 

 grown, as a result of our six appearances in public. 



Volume II shall greatly excel volume I in many ways. Our 

 general plan of giving plain, practical help will remain the same, but 

 the journal will be exclusively devoted to practical microscopy. 



Among the good things in store for the readers of Vol. II will 

 be the following: 



"The history of the microscope and microscopical accessories." 

 By J. VV. Crumbaugh, M.D., of Philadelphia. The first article will 

 appear in our next issue and will be continued throughout the year. 



"Continuation of the articles on mounting and staining." By 

 W. H. Walmsley. 



" Some articles on practical optics, and the manufacture of 

 microscopes." By Mr. E. D. Bausch, of the firm of Bausch and 

 Lomb, Rochester, N. Y. 



Prof. Allyn Y. Moore, M.D., of Cleveland, will contribute an 

 illustrated article in our next issue on the structure of the red blood- 

 corpuscles. Prof. Moore has been studying this subject at great 

 length, and will give our readers solid proof of a very important 

 discovery. 



Geo. E. Fell, of Buffalo, treasurer of the American Society, will 

 contribute later in the year. Articles are promised from "Grey 

 Beard," R. N. Reynolds, Prof. Lobdell, and many others. Three 

 full page lithographs of urinary crystals are all ready and waiting 

 for room. We promise first-class press work, as good as we are en- 

 joying from the publishing house of Geo. S. Davis. 



Renew promptly, please, and we will promise a good journal 

 for volume II. 



WE have had the pleasure of examining a number of mounts of 

 arranged diatoms, the work of Dr. F. S. Newcomer, of Indi- 

 anapolis. They are models of neatness and good taste, and we 

 doubt if they are excelled in this country.
