Discussion on How Insects Melt Snow
(S108a: 1865)

Editor Charles H. Smith's Note: An account of Wallace's brief discussion of a note concerning high altitude insects. Conducted during the 3 April 1865 meeting of the Entomological Society, and later reported in their Journal of Proceedings series for 1865. Original pagination indicated within double brackets.

    [[p. 90]] In reply to enquiries, the President [[F. P. Pascoe]] added that the insects in the snow were all dark in colour, that the holes were on the slope of the mountain on which the sun was shining directly, and that they were truly cylindrical, not hemispherical, or narrowed [[p. 91]] at the bottom. His explanation of the phenomenon did not meet with general acceptance; it was objected that radiation was scarcely likely to produce a cylindrical excavation; and Mr. A. R. Wallace doubted whether an insect of so small bulk and mass, and which could only give off by radiation the heat which it had first absorbed, was capable, even though of dark colour, of absorbing sufficient to produce the considerable melting of the snow around it which the President had described.
