34 WESLEY MILLS ON 



They were not examined as to reflexes other than sucking, reaction to temperature, etc. 



I made on the first day the following experiment : — Placing a puppy on a surface above 

 the floor it was found that when it reached the edge it became very uneasy, spread its claws, 

 grasped, etc., to avoid falling ofl^. 



On this and later days they cry apparently from cold or hunger or when removed from 

 the usual environment. 



ith dm/. — The last experiment is repeated under slightly varying conditions. A tor- 

 toise placed under the same conditions walked or tumbled oÛ'. On this day one puppy was 

 conveyed to my laboratory wrapped up warmly in a blanket, without a cry or other sign of 

 discomfort — this journey occupying about half an hour. 



5;/i d'ltj. — When pinched, they give evidence of feeling by a cry and movement, though 

 the latter is not very marked. "When the hand is laid over them in a caressing way just 

 afterwards they are at once cpiieted. I regret that this experiment was not made earlier. 



6th day. — Several attempts are made to ascertain if they smell, but with uncertain results. 

 "Warm milk and meat were held near their noses. I think there was some sniffing as a re- 

 sult, but cannot be certain. 



7th day. — Growing well. Two specimens (females) weigh 2 lbs. 7 oz. and 2 lbs. 10 oz. 

 respectively. Tested taste b}- the use of milk and of aloes. A finger dipped in milk is long 

 sucked. "When aloes in solution is placed on the finger the latter is not long sucked, and 

 the facial movements indicate disgust ; C£uite the reverse in the case of anything sweet. I 

 endeavoured to learn whether the}' knew if the dam were near them by smell, but could not 

 establish it. Up to this date and long after no evidence of hearing to be elicited. 



9th day. — "When the dam is out of the pen as she now often is, the puppies suck fre- 

 quently at different parts of the bodies of each other. They will suck vigorously and for 

 some time at my finger. 



It is easy to notice uoav great progress in power of movement, especially as regards the 

 fore-limb, mouth parts and head or neck. Xo movement of the tail at all yet nor for some 

 time. 



lO^A day. — I again attempted to determine whether they could smell, in the same 

 manner as before, but with no definite results, though strongly inclined to believe that 

 the}- could to some extent. 



"When the dam after an absence steps into the pen, two or three may happen to get 

 between her legs after she lies down. Presently these and others commence to move in a 

 lively way in all directions, and before long manage to reach the teats. 



llih day. — Held a saucer containing warm milk under the nose of one of the puppies. 

 It took the edge of the saucer in its mouth. Another tried to drink the milk but did not 

 succeed, its eagerness being in excess of its ability to co-ordinate muscular movements. 



The evidence of smell is still very doubtful. 



It is now easy to discern that some are larger and in better physical condition than 

 others. 



l^th day. — Last night it was observed that the eyes began to open. At noon to-day 

 they are not fully open, being held by a thin sheet of tissue at the outer canthus ; individual 

 differences are very marked, however, in this matter. 



Smell is tested with pieces of cold cooked veal, warm fried kidney and cold cooked 

 salted herring. All, when these were put near the nose, lic/,ed their lips and moved forward 

 and to each side, following the objects evidently by the nose.
