Limaces terrestres five Cochlaeae terrestres. The Snail: an animal, lodged in a short thick turbinated shell, whose aperture is closed in the winter with a kind of cement. The large ash-coloured snail is said to be the species intended for medicinal use; but the smaller, dark-coloured, spotted, striped sort, more common in gardens, is taken indiscriminately, and appears to be not at all different in quality from the other.
This animal abounds with a viscid slimy juice, which it readily gives out, by boiling, to milk or water, so as to render them thick and glutinous. The decoctions in milk are apparently very nutritious and demulcent, and stand recommended in a thin acrimonious state of the humours, in consumptive cases, and emaciations.
