 ing it is obviously impossible that he could bite, as bis mouth 

 is towards bis own chest, so it is the best way of showing how 

 far he is from thinking of hostility. 

 February 28, 1881. 



The above account may be taken as fully trustworthy. 

 Most of the observations recorded I have myself subse- 

 quently verified numberless times. From the account, 

 however, several observations which I happened to make 

 myself in the first instance are designedly omitted, and 

 these I shall therefore now supply. 



I bought at a toy- shop a very good imitation of a 

 monkey, and brought it into the room with the real 

 monkey, stroking and speaking to it as if it were alive. 

 The monkey evidently mistook the figure for a real

 looking over his shoulder at the image, and, with a pre- 

 posterous amount of * pinch ' in his back, strutted up and 

 down before the glass with all the appearance of the most 

 laughable foppery. This display was always gone through
