2 i6 THE MICROSCOPE. 



Meanwhile, let us hope that there are more than four men in 

 the world working industriously and faithfully at the same problem, 

 and that none of them will be ridiculed or ostracized for the 

 opinions they may advance, before the grounds upon which they 

 base their conclusions are promulgated and dwelt upon. Then, 

 should it come to pass that, in these investigations, the often ex- 

 pressed theories of favorite scientists should be opposed by new, 

 demonstrated facts, why, so much the worse for the theories. 



Perhaps I should heed the challenge of Prof. Stowell's article. 

 Since I have already, in very numerous instances, submitted to the 

 test he suggests, without once failing in distinguishing human from 

 dog's blood, I see no good reason for denying him the pleasure of 

 this little by-play. 



One word with regard to the Wellsboro murder case, which has 

 been so much referred to. The blood stains submitted to me for 

 examination, were claimed by the prisoner, to be caused by 

 the blood of a dog which he had killed the day before his arrest. 

 No other animal was mentioned as a possible cause. The stains 

 were liberal and an abundance of corpuscles obtained therefrom. 

 By means of mounted slides of human and dog's blood, compared 

 with similar slides of the suspected blood both by microscope and 

 photographs, no difficulty was found in showing that the stains 

 could not have been caused by dog's blood. Since his attorneys 

 had an opportunity of examining and comparing the two bloods in 

 the various ways mentioned, I was glad of the corroborative 

 evidence on their part that induced the criminal to adopt the more 

 plausable explanation of "nose-bleed."
