60 THE MICROSCOPE. Apr. 



})ut yon denounce all difssection of cats even in high schools be- 

 cause as you say " not over one child in a thousand has a bent 

 for zoology." 



Mr. Angell sends out a " beautiful placard " containing the 

 exhortation : " Don't ride in any vehicle drawn by a poor-look- 

 horse," but in all his literature we find no allusion to withdraw- 

 ing patronage from poor looking men, women or children. 

 Why not be consistent in your folly, Mr. Angell ? 



Illustrations might be multiplied of these unfortunate lapses 

 in common sense. The one which really led to our writing this 

 article, may close our remarks. In his April number is an ar- 

 ticle of nine lines headed " Cornell University." He first quotes 

 some one as saying that Prof. Bert G. Wilder in his " Physiolog- 

 ical Practicums " has published explicit directions for examin- 

 ing portions of the cat, and the heart, eye and brain of the sheep 

 as an aid in the stud\" of elementary physiology. His com- 

 ment thereon is: "The whole freshman class at Cornell came 

 near being murdered recently by scientific suff'ocation, which 

 caused the death of the poor woman serving them." We call 

 on Mr. Angell in the name of every friend of this distinguished 

 anatomist to either withdraw or to justify this inuendo which 

 on its face appears senseless and cowardly.
