Maquenne and Roux discuss the autoexcitation of malt, the opti- 
mum in malt autoexcitants, autoexcitation in relation to amylopec- 
tine, origin of the dextrins of saccharification. — Comp. rend. Acad, 
des Sc. Par., 1906, v. 142, pp. 1386-1392. (See also J. de pharm. et

Camus, L., concludes that hordenine has incontestable antiseptic 
properties, in vitro , but, as its effects in vivo are somewhat distress- 
ing, it is not to be recommended for this purpose in intestinal affec- 
tions. He thinks, however, that it possesses other properties which 
entitle it to the consideration of the therapeutist, such as its action 
on the cardio- vascular apparatus, the digestive apparatus, and the 
secretions. On these grounds it is to be recommended in all affec- 
tions in which malt preparations have proved useful and should 
prove more uniformly active. — Arch, internat. de pharmacod. et de 
therap., 1906, v. 16, pp. 43-206.

McMillen says a good indication for liquid malt extracts is a sense 
of fullness, with heat in the abdomen, from one to several hours after 
eating — a feeling of imperfect digestion. The patient often wakes 
at night and is restless, tosses about in bed, with the sense of heat 
and fullness. A single dose of one or two ounces will often give 
relief. This remedy should not be repeated day after day, but lim- 
ited to a single or a few doses at a time, as a special, not a general, 
remedy. — Eclectic Med. J., Cincin., 1906, v. 66, p. 161. 
MANGANI DIOXIDUM PRJECIPITATTJM. 
Hankey, William T., asserts that precipitated manganese dioxide 
is not a regular article of commerce, and when obtainable the price is 
out of all proportion to its value. — Am. Druggist, N. Y., 1906, v. 49,

MANNA. 
Hooper, David, mentions a new source for manna, an exudation 
from the tree Schrebera swietenoides Roxb., allied to the ash trees 
which afford the commercial manna of Europe. The exudation dis- 
solves in five times its own weight of water, and yields to boiling 
alcohol a crystalline constituent having the properties of mannite or 
mannitol. — Pharm. J., Lond., 1906, v. 23, p. 258. 
Dieterich, Karl, reports on 18 samples of manna. The ash con- 
tent varied from 0.07 to 5 per cent and the contained moisture from 
4.58 to 13.15 per cent. — Helfenberger Annalen, 1905, 1906, v. 18, p. 96.
