The Microscope. 113 



It is with deep regret that we chronicle the death by typhoid- 

 pneiimouia of Dr. Bernard Persh. hospital steward of the U. S. 

 Frankford Arsenal, aged 37. Although personally unacquainted 

 with Dr. Persh, he was well known to us through his microscopical 

 work, and lately by his active interest in photo-micography. His 

 death is a loss to the scientific world. 



We understand that Dr. Thomas Taylor's report for 1886 to the 

 Commissioner of Agriculture contains 114 photo-micrographic illus- 

 trations of butter and fats . The photography is in the highest style 

 of the art, and was done by Mr. W. H. Walmsley and the late Dr. 

 Bernard Persh, of Philadelphia. If these photographs are in- 

 cluded in the govermnent report, it will make a decidedly interesting 

 volume. 



The push and enterprise of the firm who are now publishing 

 The Microscope was well exemplified in our last number. The report 

 of the New York Microscopical Society arriving after the body of the 

 joiu'nal had been })rinted, the publishers not only suggested but 

 offered space in the advertising pages in order that our readers might 

 have an early report of the meeting. That the attempts to make the 

 Microscope the leading joiirnal of its kind, and a credit to American 

 microscopists, is appreciated, the daily large additions to our sub- 

 scription lists show. We have I'oom for many more, however, and 

 we trust that all subscribers will see to it that every friend interested 

 in microscopy knows of the existence of this magazine. 



W^E desire to again call the attention of correspondents and ex- 

 changes to the fact that this magazine is no longer published at Ann 

 Arbor. All communications, exchanges, etc., should be addressed to 

 The Microscope, 83 Lafayette avenue, Detroit, Mich.

Correction. — The cut on page 65 of 

 the March number of The Microscope, 

 which has the name Cos. Excavatus, var. 

 Greville, should have been labeled, Amphi- 

 tetr as (Biddulphia) Altemans, n. s. The 

 mistake was ours, the plates arriving too 

 late for Mr. Christian's inspection.
