ferent parts of the body. Professor Quekett 

 observes, that the minute structure of the hair 

 of different species of the same genus or family 

 is so constant, that a practised eye can readily 

 discriminate between them. 1 A specific variety, 

 with a general similarity, has been observed in 

 the hair of sixteen species of the Bat tribe. The 

 hair of the Indian Bat is well known as one 

 of the most beautiful examples of microscopic 

 illustration. The studies of the Microscope thus 

 ever and anon reveal to us infinite variety, as 

 well as exquisite uniformity, in the very smallest 

 of the works of the Almighty, and suggest the 

 question, " Who can by searching find out God ?" 

 The apparently endless diversities of the struc- 

 ture of the parts of animal bodies, as surveyed 

 by the Microscope, have frequently in our own 

 and foreign countries, determined the issues of 

 life and death in cases of the last importance. 



(1.) A remarkable instance occurred in France 

 in 1837. A savage murder was committed on a 

 summer's eve, on the edge of one of the forests 

 in Normandy. A labourer, returning from his 

 daily toils, was stricken down by the hand of an
