Hyla viridis, Bombinator igneus and Bufo calamita were all 
sensitive to dry-he at applied to the skin or sensory nerves. 
e frogs examined in September gave the same result as 
hosei examined previously. In the beginning of October, in sev- 
eral R. temporaria the skin was found to be no longer sensitive to 
dry heat, the sensory nerves, however, remained sensitive to this 
irritant. The Rana esculenta were as in the previous month. 
The first week of November the temperature was almost con- 
tinually below the freezing point. On examining the sensitive- 
ness for heat, I found that the Rana esculenta had become quite 
sensitive to impressions of heat. The frogs of the temporaria 
species had at the same time their sensibility for this irritant 
greatly reduced. At this time I received, through the kindness 
of my friend Mr. Richard Lomer, who assisted me in quite a 
number of my experiments, a number of frogs from Heidelberg. - 
At Heidelberg Mr. Lomer found that the skin of the Rana escu- 
lenta could be = nei by dry heat, while that of the Rana tem- 
poraria could n 
Hihediately o on 0 Whit arrival these frogs were examined, and 
both varieties were found to be sensible to heat, though the frogs 
of the esculenta species responded much slower than the tempo- 
raria. At the moment of writing (Nov. 23d) almost all the Rana 
esculenta are insensible to heat. They become sensitive to this 
agent when their brain has previously been destroyed. Though 
this is true of the terminations of the sensory nerves in the skin, 
it is not true of the nerve trunks, these always remaining 
insensible. 
All the vate of Batrachians that I have thus far examined, 
appear to be sensible to moist heat from 35° C. upwards. 
eg tt 18 ak for me to continue these observations on 
but a very limited number of Batrachians, it would afford me 
researches, inclined to assist me in these investigations. It would 
be of great interest to know in all these examinations the locality, 
the time of the year and the temperature of the era pre 
atmosphere in which the experiments are made.—B, F. Lau
