doses of gin to stop his growth, and I must with shame 
confess that more than once he became drunk and incapable. 
After a while he seemed to take quite a liking to his grog, 
until one day, someone having been taking some rum and 
honey for a cold, put a few spoonfuls in a saucer, and placed 
it before Toby on the floor. He immediately began lapping 
it up, and, after wincing a little at the strength of the spirit, 
licked the saucer dry. The result was that Master Toby 
finished the evening lying on his back upon the hearthrug, 
with all four legs extended perpendicularly. The next morn- 
ing melancholy was the spectacle presented by the debauchée 
of the previous night. With head drooping and tail hanging 
straight down he wandered about, evidently seeking repose 
for his aching and bemuddled brain. If we could have got 
him to take it, we should have offered him some soda water 
and brandy, or a Seidlitz powder; but, strange to say, from 
that hour to this nothing can induce him to drink out of a 
glass or spoon, and if he is shown a tumbler he immediately 
retreats under the sofa or table, having evidently (mentally 
at least) signed the pledge, and meaning to keep it.” 
The whole mammalian class presents nothing more astonish- 
ing in function than the olfactory sense of the dog. In 
some of the invertebrata this sense may possibly be even 
more acute, for Dr. G. T. Romanes’ splendid investigations 
into the nervous system of the Echinodermata have shown 
the olfactory sense of those simple organisations to be so 
highly developed as to almost entirely appropriate to itself 
the functions of the nervous system, and to be the only 
guide to their food. But we search among the higher 
animals in vain for evidences of perception and discrimina- 
tion by means of this sense at all approaching the results 
attained in the dog. Some physiologists have questioned 
whether it does not differ in kind as well as in degree from 
the same sense in man and other animals. In degree it 
certainly differs to an extent of which we can form no sub- 
jective idea, and it may possibly be negative with regard to
