In Scrofzila, the Chloride of Calcium was first advised by Fourcroy, and it was subsequently employed with success in several instances by Dr. Beddoes.* Others have testified to its value. Dr. Wood speaks of it as a safe and efficacious remedy; Dr. A. T. Thompson states that he has seen more benefit from its continued use than from any other medicine; and M. Cazenave§ considers that it is a valuable remedy, having successfully employed it in several cases. In opposition to this evidence, Dr. Thompson,|| of Edinburgh, states that he found its use prejudicial in many cases of Scrofula, and Mr. Samuel Cooper¶ observes that he gave it in several instances without benefit. M. Cazenave advises it in doses of gr. xv. - xxx. daily, in some vegetable infusion.
