From inquiries made at several of the large dispensing houses in Liverpool, I find that the demand for leeches has dwindled down to a mere tithe of what it was ten years ago. At most of the hospitals and dispensaries they are so rarely required, that they are not kept in stock at all, but sent for when ordered. As for cupping and bleeding from the arm, they are never heard of now. The following cases show the mistake which will be made if  blood-letting is altogether lost sight of or omitted from our therapeutics.
