town, and on my arrival the mouse was in good condition. But 
the next morning it was again apparently dead ; in the course of 
the day, however, being placed where it was warm, it gradually 
came back again to activity as before. 
This mouse, then, when dug from the mound was in a state of 
the most profound lethargy, —if torpidity be too strong a term,— 
and it is safe to infer that it would have so remained till spring, 
had it not been removed into a warmer temperature; and this 
lethargy or torpidity was as intense, so far at least as regards 
external appearances, as that seen in other animals, not except 
ing reptiles and batrachians. 
I may add that the observations above detailed show that this 
mouse is capable of passing into the deepest lethargic state ina 
single night, and of returning, when warmed, to activity again on 
the succeeding day. 
The Jumping Mouse is very quiet in the daytime, but very 
active at night. When disturbed in its nest it vigorously repels 
the attack by striking with its fore feet with the greatest rapidity. 
It apparently does not seek to bite me. i 
Since the above was written the mouse has repeated the exhibi- 
tions detailed above, and at least once since the begiuning of 
April. A colder night than usual seems to furnish the occasion 
for it to go into a state of the most profound lethargy.
