In many cases even of irritative dyspepsia, when the tongue is furred, with red edges and tips, and there is pain after food and heartburn, and tendency to diarrhoea after eating, I have had ample experience of the value of Fowler's solution given in 2 or 3-min. doses after meals. Dr. Thorowgood finds that it acts best when the attack seems localized in the stomach, and is independent, e.g., of hepatic congestion (Practitioner, 1870). Dr. Anstie, whose first published observations were directed to the value of arsenic in gastralgia, previously mentioned to me its equal efficacy in the dyspeptic conditions described.
