42 Instinct and Memory exhibited, etc. [ January, 
kinds of nuts from among three others which, beyond much 
question, were the only ones of the five named with which his 
near ancestors had anything to do? It should be stated in this 
connection that the squirrel had eaten of the other nuts during 
at least two months prior to the selection in question, with as 
much apparent relish as he evinced for either the hazel-nuts or 
acorns. This particular squirrel, only about five months old, had 
had no experience whatever with nuts except in confinement, and 
of course had never before attempted to bury them. Have we in 
this instance and in similar ones, evidence that an act, executed 
repeatedly during particular seasonal conditions, and under cer- 
tain sense-impressions, as sight and smell, may impart so definite 
a set to the organization as that it shall be transmitted to an off- 
spring? Is this set a molecular one and located in the nervous 
tissue? Is it so sensitive that if, when the body is experiencing 
those seasonal changes due to the change of seasons in the earth 
during which the original set had its origin, a combination of vibra- 
tions (those accompanying the sight and smell of an acorn, for ex- 
ample) like those which were instrumental in producing the set, are 
again imposed upon the nervous tissues, similar feelings will be 
- awakened which tend to culminate in a desire like the ones which 
had prompted former generations to the act in question? And 
in this way to a repetition of that act? Did not Skip on the 
night in question experience a true recollection in which the 
memory he had inherited was jogged by the combination of the 
sight and smell of acorns and the systemic feeling of approach- 
ing winter ? : é 
On the 27th of June, 1880, I left Skip with a little girl to be 
cared for during my absence, which lasted through the summer ; 
when we met again, about the middle of September, Skip showed 
unmistakable signs of a distinct remembrance of me by playing 
. upon my person, in his usual manner, with great freedom. The 
most decided test, however, of his keen memory, was exhibited 
when he was allowed to play in the closet where Mrs. King’s — 
wardrobe hung beside my own. He played with unusual vigor and 
for a long time upon my garments, running in and out of pockets, 
but exhibited great caution in touching hers, only alighting upon 
them to jump to some of mine. He had never seen Mrs. King 
before the evening on which this frolic occurred.
