A case is reported in a recent number of the _Bulletin Universel_, by a French physician, M. Bourgeois, showing the importance of never abandoning all hope of success in restoring animation. A person who had been twenty minutes under water, was treated in the usual way for the space of half an hour without success: when a ligature being applied to the arm, above a vein that had been previously opened, ten ounces of blood were withdrawn, after which the circulation and respiration gradually returned, though accompanied by the most dreadful convulsions. A second, and a third bleeding was had recourse to, which brought about a favourable sleep, and ultimate recovery on the ensuing day. _Iron_. It is a singular fact, that the value of the iron annually produced in England greatly exceeds the value of the silver annually produced in Peru. _Hair_. At a recent meeting of the Academy of Sciences, at Paris, M. F. Cuvier, in a memoir on the generation of feathers, spines, and hair, introduced the following curious conclusion:--"I consider the organic system which produces hair as analogous to that of the senses, and even as forming part of them; for the hair is in a great number of animals a very sensitive organ of touch. It is not only in mustaches that we have a proof of it, but on the whole surface of the body. The slightest touch of a hair is sufficient in cats, for example, to make them contort their skin and shudder, as they do when they find something light attached to the hair, and that they wish to shake off." _Population of England_. The United Kingdom of Britain and Ireland contains 74 millions of acres, of which at least 64 millions of acres may be considered capable of cultivation. Half an acre, with ordinary cultivation, is sufficient to supply an individual with corn, and one acre is sufficient to maintain a horse; consequently, the united kingdom contains land enough for the sustenance of 120 millions of people, and four millions of horses.--_Edmunds on Political Economy_. _Singing_. The following passage from a letter by the late _Carl M. Von Weber_ appears to be worthy of the attention of dramatic and other singers:--
