By ROGER VERITY, M.D., and ORAZIO QUERCI. 



Introductory Remarks bv R. Verity. 



{Continued from page 183.) 



These notes will, I hope, go some way towards showing what a 

 fascinating study geographical variation is, and what interesting 

 observations can be made by a comparison of races, when they have 

 been properly defined. The list, to follow, of the races of Peninsular 

 Italy, is a proof that they are anything but indefinite and unlimited in 

 number, as it was, till quite lately, supposed. It is perfectly clear that 

 each species rarely produces more than one or two races in each of the 

 zones I have mentioned, and that, on the contrary, the same one 

 extends very often to more than one zone, so that the aim of reaching 

 a tolerably complete knowledge of these races is anything but a hope- 

 less undertaking. The more the zones have been worked out the more
