Specimen of chloroform.
[The inestimable results which have attended the intro-duction of the anaesthetic or painless mode of operatingin surgery, renders the principal medical product em-ployed highly interesting.

[To the chemist the preparations known as alkaloids,or vegeto-alkaloids, present many features of peculiar in-terest. They are also of the highest medicinal import-ance, acting, as many of them do, with extraordinarypower over the animal economy, and supplying to thephysician remedies of such energetic action as to enablehim, in many cases, to reduce the bulk of medicine froman inconvenient and uncertain, to a convenient form.The crystallization of the vegeto-alkaloids is peculiarlybeautiful, and their chemical constitution is extremelycomplicated. Morphia , quina, strychnia, and brucia,are among these peculiar products, and possess intensemedicinal energies.—R. E.]
