in such cases, if the progress toward recovery is not continuous. —

Collins, C. D., in discussing the treatment of pruritus vulvse, says 
that belladonna is indicated by — 
Bright red and shining skin. The itching is relieved by scratching, which 
produces a pleasant sensation. Voluptuous itching, especially adapted to 
nervous patients with much headache and a vindictive temperament. — Trans. 
Am. Inst. Homoeop., 1906. 62d sess., Part II, p. 286. 
BELLADONNA RADIX. 
Lyons, A. B., reports that only 1 out of 12 replies received, thought 
the standard of 0.5 gm. of mydriatic alkaloids in 100 c. c. of fluid 
extract of belladonna root satisfactory and readily maintained. He 
himself found that 4 out of 7 lots of fluid extract ran over the re- 
quired strength. — Proc. Am. Pharm. Ass., 1906, v. 54, p. 437. 
Patch, E. L., found from 0.53 to 0.64 per cent of alkaloids in bella- 
donna root. — Ibid., v. 54, p. 334. 
Evans Sons Lescher and Webb assert that belladonna root is very 
Available in alkaloidal content ; that the alkaloidal content of the 
samples examined for the year ranged from beloAv 0.1 per cent to be- 
tween 0.4 and 0.5 per cent. In one case the alkaloid was practically 
absent. — Analytical Notes for 1906, 1907, pp. 8-9. 
Dott, D. B., asserts that belladonna root is more readily exhausted 
by 60 per cent than by 80 per cent alcohol. The powder being of a 
bulky, spongy nature does not favorably lend itself to repercolation. 
It is better to macerate and press. — Yearbook of Pharmacy, 1906, 
p. 300. 
Taylor, S., thinks that, as a result of the work of Farr and Wright, 
the Ph. Brit, will direct extracts to be in the powdered form wherever 
possible. This form secures absolute uniformity of condition ; also 
strength in the standardized extracts. If carefully kept, these prod- 
ucts are only slightly hygroscopic, and, with proper care, need cause 
no trouble. As a diluent he considers that milk sugar is generally 
successful and much adA T ocated; the addition of some dried efflo- 
rescent salt would certainly tend toAvard keeping the condition of 
the extract, though the addition of active bodies is to be deprecated. — 
Pharm. J. Loncl., 1906, v. 23, p. 669. 
The Ph. Brit. Committee of Beference in Pharmacy recommends 
that the assay process for liquid extract of belladonna be amended ; 
it also belieA T es that an assay process for belladonna plaster is de- 
sirable; it suggests a re au si on of the wording of the monograph 
on alcoholic extract of belladonna, and the requirement that the 
product be in dry powder; and recommends adding an assay process 
for liniment of belladonna. — Chem. & Drug., Bond., 1906, v. 69, 
pp. 863-864.
