Again, after the discovery of the method of hypodermic injection by Wood in 1853, the local anaesthetic power of morphia and chloroform was tested by this method, in the latter case with the result that the pain of the injection often greatly exceeded that of the operation itself Of other sedative substances and methods which have been experimented with and recommended, mention may be made of hydrocyanic acid {Simpson), carbonic acid externally applied [Perci- val, 1772), and saponin hypodermically injected (Pelikan). The question of the production of local insensi- bility to pain acquired an altogether greater practical importance with the commencement of our knowledge of the local ansesthetic pro]3erties of cocain. Leaves of the coca-plant were brought to Germany by Scherzer from South America, where their partly stimulating and tonic and partly sedative effects had long been known. In several German laboratories investigations were made with a view to the discovery of the true active principle of the plant. At first it was thought that this had been discovered in a body to which the name erythroxylin was given. Later, however, the claims of this body were entirely thrust aside in favour of those of a substance dis-
