of soda ; a precipitate ensues. This must be removed by filtration 
and the solution is then ready for use. 
Iron, as an impurity, is always associated with native oxide of 
manganese, and when that substance is acted on by acids, giving 
rise to salts of the protoxide ; the iron also unites with them and 
forms soluble compounds, and it becomes necessary to get rid of it 
by subsequent precipitation. This is facilitated by its showing 
less inclination to remain in saline combination, than the oxide of 
manganese ; and consequently by taking advantage of this pro- 
perty, these metals can be readily separated when in solution, by 
heating in contact with carbonate of manganese or soda. The 
whole of the iron by these means is throw T n down, and then by 
filtering, and using a larger quantity of bi-carbonate of soda, 
carbonate of manganese can be obtained pure. 
ON SCUTELLARIA LATERIFLORA. 
To the Editor of the American Journal of Pharmacy. 
Respected Friend, — The article in the last No, of the Journal, 
page 370, by C. H. Cleaveland, M. D., on Scutellaria lateriflora, 
calls to mind some of my experience, coinciding with his, which 
I offer in hopes it may prove a benefit to some of the afflicted ; 
and because a remedy which is not much known, or has but little 
reputation, requires testimony in its favor to call it into notice. 
About twenty-five years ago my wife had quite a severe attack 
of tic doloureux on one side of her face, and as the scullcap had 
been a good deal spoken of as a remedy for hydrophobia, I deter- 
mined to try it in this case, supposing its influence to be exerted 
on the nervous system. By the use of two or three pints of infu- 
sion, made with an ounce of the herb to a pint of boiling water 
and taken in doses of a wine-glassful three or four times a day, the 
disease appeared to be entirely relieved : in the course of a week 
or ten days, however, it returned, when the scullcap infusion was 
again resorted to, and continued several weeks, after which there 
was no return of the disease on that side. A few years after this 
period my patient was attacked on the other side of her face, but 
the diligent use of the Scutellaria, as before, soon relieved her, and 
she has, ever since, remained free from that painful disease.
