Several members of the Paris Anthropological Society have promised each to write a will directing that his brain be sent to the society, for inspection and dissection. It is thought that, by procuring the thinking organ of persons whose habits and works are perfectly known, some light might be thrown on the laws of physico-mental organization.

On and about pistons and journals which have been lubricated with animal and vegetable oils, lumps of dirty matter are found, consisting of iron oxide and fatty acids. Dr. Schondorff has found that the oil is decomposed by steam into glycerine and fatty acid, and that the latter attacks the iron, causing enlargement of the cylinder. He therefore recommends the use of heavy mineral oils as lubricators.

It is stated in Land and Water, as a fact beyond contradiction, that the choice English breeds of cattle have for some years not only tended to diminish in size, but also 'in robustness of constitution. The milk-yielding qualities of English cattle, too, are declining, so that the importation of cheese and butter is increasing enormously. This is strikingly the case with the Durhams, in which everything is sacrificed to form. In the finest strains of Durham cattle fecundity has been seriously affected, and the milk-secretion has become next to nothing.
