8o THE ORIGIN OF HUMAN REASON. 



bitch or a she-cat does not seem to miss a single pup 

 or kitten which may have been taken away from the 

 others in her litter. 



Mr. Romanes naturally makes a great deal of the 

 chimpanzee " Sally " at the Zoological Gardens, which, 

 he tells us,* has been taught " to count correctly as far 

 as five." The result of our own investigation with 

 regard to this ape was as follows : — 



It is most true that the animal is finely gifted, and 

 that it does separately pick up from the ground, place 

 in its mouth, and then present in one bunch, two, three, 

 four, or five straws, as may be demanded of it, or only 

 one. It has distinctly associated the several sounds of 

 these numbers with corresponding groups of picked-up 

 straws. The ape will also, on command, pass a straw 

 through a large or small hole in the fastening of its 

 cage, or through a particular interspace of its wire 

 netting. It will also put objects into its keeper's pocket, 

 play various odd tricks with boy visitors, howl horribly 

 when told to sing, and hold on its head pieces of apple, 

 remaining perfectly quiescent till a particular expression 

 is used. This last trick, however, is one of the com- 

 monest of those performed by pet dogs, and the putting 

 of objects into the keeper's pocket is nothing remarkable. 

 The passing of a straw through a special aperture on 

 command would be more so, but for the fact that the 

 basis of the whole superstructure of such tricks was laid 

 by the animal itself (as the keeper told us), which had 

 spontaneously taken to the trick of picking up a straw 

 and passing it through a small hole near the keyhole of
