In compiling this part of our hints, we have endeavoured to supply that kind of information that is so often wanted in the time of need, and cannot be obtained when a medical man or a druggist is not near. The doses are all fixed for adults, unless otherwise ordered. The various remedies are arranged in sections, according to their uses, as being more easy for reference. {For the meanings of medical terms, tee Index.)
