My dear Dr. Merriam, For sane time I have been quite interested in the question of ^the classification^of the bear, as to whether it would be called a hibernating animal or not. I remember very well indeed several talks I had with you, and as I^^recall it, you made the statement that all bears were bom^*in hibernation*.* The exact interpretation of the word "hibernation" puzzles me. Ordinarily I think of this as a condition in which the animal is definitely at a very much lower rectal tenperature, and yet to my astonishment I have run across a statement attributable to Mangili, in an article published in / Paris in 1818, in which he states that the bears have the same rectal > temperature summer and winter, even if they are asleep in winter.

What would be your opinion with regard to this statement that the temperature is the same, or essentially the same, winter and summer?
