92 THE MICROSCOPE. 



for teachers, post graduates, etc., will be offered at the opening of 

 the next college year. One private pupil mounted over 300 speci- 

 mens while taking this course. 



ONE friend writes, "your last number alone was worth the sub- 

 scription price of a whole year." Another enclosed three 

 dollars for volume II and said he wished to "pay for two years in 

 advance." Another says "I have mounted everything Mr. Walmsley 

 has told us how to mount, and became so deeply interested that I 

 sold my old microscope and bought a fine new one." It is pleasant 

 to be appreciated, doubly so to be told of it. 



WE are very happy in the recent possession of a'souvenir of old 

 times in the way of a Spencer "Chevalier" microscope. It 

 was one of the first that Mr. Chas. Spencer ever made. We pro- 

 cured it from Dr. C. M. Woodward, of Tecumseh, Mich., and he 

 bought.it second handed as a souvenir over 15 years ago. The }i 

 has a remarkable working distance, but of course is sadly deficient in 

 defining power. It will not touch the p. angulatum, but Dr. Wood- 

 ward says it shows the smallest oxalates and is a very good glass yet 

 for general use. 



AN apology is certainly due our readers and Mr. Brearley for an 

 oversight iji our last number on the part of some one for which 

 we are responsible. The notice of Mr. Brearley's excursion was 

 not intended to be placed in the reading matter. Mr. Brearley did 

 not ask it to be placed there and we did not intend to have it there, 

 either. Nothing like an advertisement shall ever appear in this 

 journal outside of its proper place. 



FOR our October number we have on hand the third paper of Dr. 

 Crumbaugh; an article by Prof. H. J. Rice on The Probosis 

 and Labial Palps of the Oyster; Laboratory Notes by one of the 

 editors. Other articles have been promised. 



THE Summer School at Petoskey opens July 13th and continues 

 for five weeks. The editors of this journal have active duties 

 to perform during that time, and it would be impossible for them to
