By collecting the amount of hydrochloric acidand estimating it volumetrically by a solution ofcarbonate of soda, an approach to a quantitativedetermination of the chloroform is made. By these means MM. Lallemand, Perrin, andDuroy have determined the relative properties ofchloroform in the various portions of the systemafter death from chloroform; the blood being takenas the standard representing 1, the brain contained3-92 parts; the liver, 2-08; the muscles, 0-16. CHAPTEK EFFECTS OF THE INHALATION OF CHLOROFORM. The notions which are current concerning chloro-form and its effects are in great degree strange anderroneous. Among the public there is much per-plexity, many ideas based upon false reasoning, andmuch ignorance even with regard to the natu
