[April, 1887. 
upon the resemblance, and therefore that the inference of an ant 
or a bee feeling sympathy or rage is not so valid as is the similar 
inference in the case of a dog or a monkey. Still it is an infer¬ 
ence, and, so far as it goes, a valid one—being, in fact, the only 
inference available. That is to say, if we observe an ant or a bee 
apparently exhibiting sympathy or rage, we must either conclude 
that some psychological state resembling that of sympathy or 
rage is present, or else refuse to think about the subject at all; 
from the observable facts there is no other inference open. 
Therefore having full regard to the progressive weakening of the 
analogy from human to brute psychology as we recede through 
the animal kingdom downwards from man, still as it is the only 
analogy available I shall follow it throughout the animal series. 
“ It may not, however, be superfluous to point out that if we 
have full regard to this progressive weakening of the analogy, we 
must feel less and less certain of the real similarity of the mental 
states compared, so that when we get down as low as the insects, 
I think the most we can confidently assert is that the known 
facts of human psychology furnish the best available pattern of 
the probable facts of insect psychology.” 
Prof. C. Lloyd Morgan, in a critical essay “On the Study of 
Animal Intelligence,” Mind, No. XLII, April, 1886, p. 174., ob¬ 
jects to the method used by Romanes in the study of animal 
psychology. While appreciating the force of his argument we 
venture to suggest that it applies rather to the hasty and incau¬ 
tious use of ejective inferences than to their more temperate and 
philosophical application as instanced in the work of Romanes.
