This, however, is certainly not true, as is shown, to omit less decisive proofs, by the experiments of Naunyn and Quincke, who exposed animals for two days to a temperature of 90°, and at the end of that time, their bodily temperature not having risen, cut their spinal cords, after which intense fever was developed in a few hours without any change of atmosphere.
This want of homogeneity may, according to M. Quincke, be due to the existence of particles suspended in a liquid in contact with another liquid miscible with it and enveloping it as might a membrane, and the phenomena of polarization would thus be quite naturally explained. See Proc. Roy. Soc. A., 23rd July 1906.
From experiments on capillarity, Prof. Quincke has obtained similar results with regard to layers of solids. But it is not only capillary properties which allow this characteristic to be revealed. All the properties of a body are modified when taken in small mass; M. Meslin proves this in a very ingenious way as regards optical properties, and Mr Vincent in respect of electric conductivity. M. Houllevigue, who, in a chapter of his excellent work, Du Laboratoire
