firmed by the power possessed by men of simultaneously estimating with accuracy 
the number of a low series of small objects set before them without any direct 
enumeration. 
In addition to these attempts to determine “ Sally’s ” capacity for numbers, 
Dr. Romanes instituted a series of experiments designed to test her powers of 
recognising and distinguishing between colours. “It appeared to me,” says the 
experimenter, “ that if I could once succeed in getting her to know the names of 
black, white, red, green, or blue, a possible basis might have been laid for further 
experiments wherein these five colours could have been used as signs of artificially 
associated ideas. The result, however, of attempting to teach her the names of 
although after seven I believe that her computation of the numbers becomes 
vague.” 
Before her death, as we have been, informed by Dr. Romanes, “ Sally ” was 
able to count up to as many as ten straws; and if her life had been prolonged she 
might even have advanced beyond this. Dr. Romanes proceeds to state that it 
would be unreasonable to assume that this chimpanzee really employed any system 
of notation in delivering the correct tale of straws, and we may rather consider that 
she executed her task by a direct perception of the difference between a higher and
