The ammoniated iron was formerly known under the names Jfares 

 martiules, cnsmartis.jlores auri, and calendulas minerales. It has 

 been highly extolled as a remedy in epilepsy, hysteria, scrofula, 

 chlorosis, and rickets ; but on account of the uncertainty of the pre- 

 paration, it is never prescribed, as Mr. Brande justly observes, "by 

 those physicians who are acquainted with the chemical properties 

 of the remedies which they exhibit. It may be administered in 

 pills, in electuary, or in solution ; but the t'mctura Jerri muriatis 

 is, in all cases, a proper substitute, to which muriate of ammonia 

 is easily added by those who attribute any additional efficacy to the 

 combination." The dose is from six to ten grains, given three or 

 four times a-day. 



Muriate of Iron. — This salt, employed under the form of 

 tincture, {T'mctura Jerri muriatis,) is prepared by digesting half a 

 pound of the subcarbonate of iron, for three days, in a pint of 

 muriatic acid, and diluting the solution with three pints of alcohol. 

 It is one of the most active preparations of iron, and is given in 

 doses of from ten to fifteen drops, twice a-day, largely diluted with 

 water. Internally, it has been employed principally as a tonic, 

 particularly in scrofulous affections, and in the diseases in which 

 chalybeates arc usually prescribed ; but a L very important use has 

 been attributed to it by Mr. Cline, who strongly recommends it in 

 suppression of urine, from spasmodic stricture in the urethra, ten 

 drops being given every ten minutes, until nausea is produced. It 

 has also been beneficially employed as a styptic, in internal 

 haemorrhages. Externally, it has been used as an application 

 in ill-conditioned ulcers, and also to destroy venereal and other 

 warts.
