connection with the fact already cited that, at 

 least down to very recent times, few herds, of 

 however pure descent, failed to show an occa- 

 sional sport reverting to the horned type from 

 which they sprang. 



/ It is important to observe that where varia- 

 tions occur they rarely affect a single organ, but 

 to a greater or less extent the whole body, and 

 it is particularly noteworthy that certain or- 

 gans are in very close and intimate relations 

 with each other, and that a change or modifica- 

 tion of one is either accompanied by or quickly 

 followed by a similar one in the other. This is 

 no cause for wonder to any one who has studied 

 the beautiful adaptation in all animal life of 

 means to end, of organ to function. The all- 

 wise Creator, in His infinite foresight,* has thus 

 bound up every organism in the threads of a 

 system which is not to be raveled out by man, 

 but which may be viewed in its perfect har- 

 mony in such studies as this. Observe the cor- 

 relation of stomach and teeth in all animals; 

 compare the rodents and the ruminants, for in- 

 stance, in this respect. These major organs of 

 close and obvious functional relations are easily 

 seen as united by a close bond. Many other 

 and unexpected examples of correlation have 

 been observed. "Thus pigeon fanciers have
