TRITICUM. 
Henkel, Alice, mentions Agropyron re pens (L.) Beany., also known 
as Triticum re pens Beauv., commonly known as triticmn. couch- 
grass. dog-grass, and quack-grass, a> being found in cultiyated 
ground from Maine to Maryland : west to Minnesota and Missouri ; 
sparingly distributed in the South. Introduced from Europe. — Bull. 
Bur. Plant Ind.. U. S. Dept. Agric., 1906, Xo. 89, p. 9. 
Eberle, E. G., asserts that fluid extract of triticum could be made 
as well by digestion as by percolation. — Proc. Am. Pliarm. Ass., 
1906, v. 51. p. 150. 
TROCHISCI. 
Hommell. P. E., says that of the nine official troches only two are 
employed therapeutically to any extent. — Proc. Xew Jersey Pliarm. 
Ass., 1906, p. 108. 
Beringer thinks the troches as a class are sadly in need of revi- 
sion : there is no uniformity in size : they might have been classed 
at least into two distinct sizes. Hancock says they do not seem to 
giye satisfaction. — Ibid., p. 111. 
Eyans, John, outlines an analytical process for troches, used in 
the laboratory of Allen and Partners. — Apothecary, Boston. 1906, 
y. 18, p. 907. 
ULMUS. 
Henkel, Alice, mentions Ldmus fidva Michx., also known as Vlmus 
pubescens Malt., commonly known as ulrnus, elm. slippery elm. 
red elm. moose-elm. and Indian elm. as growing on hills, along 
streams, and in woods from Quebec to Xorth Dakota, south to Flor- 
ida and Texas. More common in the western part of its range. — 
Bull. Bur. Plant Ind.. U. S. Dept. Agric.. 1906, Xo. 89, p. 7*2. 
Blome. TT. H., found powdered or ground elm bark to be a yery 
scarce commodity. Of seyen samples examined, foreign starch was 
present in three. Four of the seyen were of little or no yalue as 
poultices or demulcents. — Proc. Michigan Pliarm. Ass., 1906, p. 101. 
UNGUENT A. 
Francis, John M., declares that the official ointments have been 
possibly the most unsatisfactory class of products in our pharmaco- 
poeia. Many notable changes liaye been made which reflect great 
credit on the subcommittee in charge of this work. — Bull. Pkarm., 
Detroit, 1906. y. 20. p. 282. 
An editorial suggests the more general use of petrolatum in the 
official ointments, in place of benzoinated lard. — D.-A. Apoth.-Ztg., 
X. Y., 1906-7, y. 27, p. 117.
