Characteristics.-Nit. mur. ac. has been proved in the lower dilutions and in the 30th; and some experiments have been made by Dr. Scott (quoted C. D. P.), who acidulated his bath with the acid, and sponged his body with acidulated water. Sponging and bathing had the same effect, and I have marked his symptoms with (b) in the Schema. Scott noticed that the symptoms were more marked as the proportion of Muriatic acid was increased. Salivation and sore mouth and throat with dysphagia were produced in Scott and the provers. Scott noticed that the salivation was intermittent. Weakness was felt by all. Headache with drowsiness. Slow digestion. Pricking pains. Symptoms were < after eating and by exercise. Nat. mur. ac. has a clinical reputation in oxaluria and gravel.
