'WONDERFULLY MADE* 21 



of a human hair, and that of the skin, &c., 

 are all points well worth our attention. There 

 is nothing in Nature, so far as we know it, 

 that is more wonderful than the human body, 

 even considered from the histologist's stand- 

 point. Our education is incomplete if we 

 have shunned all knowledge of our own system 

 and its wonders. 



The illustrations are entirely original. No- 

 thing from these negatives has ever been 

 published excepting the ' spider's foot, 7 which 

 appeared in the July number of ' Knowledge ' 

 as a whole-page illustration. 



An expression of our indebtedness is due to 

 Mr. Henry Tavener for his new discovery and 

 his permission to illustrate it the Mideopsis 

 orbicularis of pond water ; also to Dr. Joseph A. 

 Featherstone, of Tooting, for his kindness in 

 describing the histological details of several 

 sections illustrated.
