Most of our readers know that we have repeatedly brought to their attention reasons for believing that plants and insects cannot have their juices freeze in winter and yet retain subsequent life. One of our chapters, as it may also be remembered, was handed to one who stands high in scientific repute for his opinion, which was simply, "Freeze! why of course they freeze." And this was regarded as a conclusive argument against us. But now that Dr. Jousset de Belles-me has announced in Les Mondes, that "Where a pupa resists congelation, it does so by a continuous and considerable liberation of heat." and that it is to active combustion that we must attribute the faculty with which insects bear very prolonged depressions of temperature," some of our friends who knew that " of course they freeze," do not feel quite so sure about it.
