Materia Medica and Therapeutics. —We read the following among the 
announcements of Messrs. Churchill: A Dictionary of Materia Medica 
and~ Therapeutics, by Adolphe Wahltuch, M.D., nearly ready. The 
same firm has given us a memoir on the Mercurial Vapor Bath, by 
Parker. In Paris, Germer Bailliere, appeared: Fumouze, De la Can- 
tharide officinale , 56 pp. 4to., with 5 plates. We also note : Foster (Prof. 
Med. Queen’s Coll., Birmingham) Ether and Etherized Cod Liver Oil in 
the Treatment of Pulmonary Consumption.

and in the same proportions to the vehicle or solvent as authors have 
directed. The crude liquid known as impure carbolic acid is not to be 
recommended for internal administration, or even surgical dressings, etc.,
