[Letters to Editor]

Abstract

I HAVE followed the discussion in your columns on “Intellect in Brutes” attentively, and I maintain that Mr. Henslow's distinction between man's power of abstract reasoning, and the reasoning of animals from objects present to the senses (a faculty they certainly possess, if the theory of deductive reasoning, that all inference is from particulars to particulars be accepted, which, however, cannot be proved), is perfectly valid, in spite of any accidental errors of illustration.
