=Perchloride of Iron in Post-partum Hæmorrhage.=—Mr. Hugh Norris corroborates the testimony of the various obstetricians who have spoken so favourably of this styptic. Injections of strong solution of the salt instantly arrest the hæmorrhage in this dangerous class of cases. He noticed also that the perchloride has a peculiar corrugating effect on the superficial muscular fibres, as well as on the mucous surfaces. He has noticed in less than five minutes after injection that the sphincter vaginæ, which had previously allowed the passage of the hand, became so contracted that it barely admitted a single finger. From this he concludes that one of its beneficial effects in these cases is the contraction of the muscular fibres of the uterus. He lays down the following conclusions in reference to this preparation:—(1) We possess no topical styptic in efficacy at all approaching the perchloride of iron; its effects being certain, perfect, and instantaneous. (2) In _post-partum_ hæmorrhages, a solution of this salt, applied in the form of an intrauterine injection, is of the utmost value both in immediately arresting the flow of blood and also in causing a permanent contraction of the recently emptied uterus. Its presence in the cavity of the uterus _post-partum_ is not only not injurious, but on the contrary, from its well-known antiseptic properties, may frequently be productive of positive benefit in more ways than one. Mr. Norris employs a saturated (?) solution of the perchloride. All clots must first be removed, and the long tube of the syringe should be introduced thoroughly into the uterus before injection. (Ibid.) =The Cure and Prevention of Scurvy.=—In a paper in the _Lancet_, Mr. Archer Farr starts a doctrine which is yet, we think, to be proved, viz. that scurvy is not caused by the absence of certain alkalies and the presence of others. Indeed, he refers scurvy to the absence on ship-board of proper flesh-food, and he thinks that by supplying flesh in thoroughly good condition scurvy may be avoided. Lime-juice acts, he says, by taking the place of the gastric juice and digesting the food, and thus promoting the nutrition of the body (!). (See _Lancet_, March 27.) =Treatment of the Vomiting of Pregnancy.=—Mr. John Harrisson recommends that in these cases hypodermic injection of morphia be tried. He gives the report of a very decided and serious case, in which nearly every conceivable remedy had been employed in vain. He then tried the subcutaneous injection of acetate of morphia, in doses of one-sixth of a grain, three times a day, and this instantly arrested the vomiting.
