or common horse-chestnut. See Aesculus, Botany Index.—It may be here added, that from several experiments in the French Memoires d'Agriculture, it appears that the fruit of the horse-chestnut affords a wholesome nourishment for cattle, and may even be employed with success for fattening them. It is said to render the tallow of those fattened with it particularly firm. The milk yielded by cows fed upon it, is also said to be thicker and richer than that produced from any other kind of food.—The fruit of this tree has been likewise used as food for sheep and poultry, and as soap for washing. It was much employed in powder as a sternutatory by an itinerant quack, and has been recommended by some others in certain cases of ophthalmia, headache, &c. in which erythines are indicated. Its effects as a sternutatory may also be obtained by using it under the form of infusion or decoction drawn up into the nostrils. And it is entirely with a view to its erythine power that it is now introduced into the pharmacopoeia of the Edinburgh college.
