OLEUM HEDEOMiE. 
Henkel, Alice, mentions Hedeoma pulegioicles (L.) Pers., commonly 
known as hedeoma, American pennyroyal, tickweed, and squawmint, 
as growing in barren woods and dry fields, Nova Scotia to Minnesota, 
south to Nebraska and Florida. — Bui. Bur. Plant Ind., U. S. Dept. 
Agric., 1906, No. 89, p. 35. 
OLEUM HYOSCYAMI COMPOSITUM N. F. 
Kreytschy, Ottakar, suggests an improved method for the prepara- 
tion of oil of hyoscyamus. The formula is given. — Pharm. Ztg., 
Berk, 1906, v. 51, p. 17. 
Lefeldt, Max, suggests that an “ Oleum Hyoscyami ” Ph. Germ., 
much richer in alkaloids may be obtained by mixing 100 gm. of the 
coarsely ground hyoscyamus leaves with 75 gm. of alcohol and 3 gm. 
of aqua ammonia. Allow to stand for twenty-four hours in a closely 
covered vessel, then mix with 1,000 gm. of olive oil, with repeated 
stirring, until the alcohol and the ammonia have been completely 
dissipated. — Ber. d. pharm. Gesellsch., Berk, 1906, v. 16, pp. 340. 
Philipp Rbcler, Wien, outlines a method of assay for Oleum Hyos- 
cyami (for which 500 gm. of the preparation are required) and re- 
ports the examination of three samples which contained 0.0028, 
0.0198, and 0.0245 per cent of alkaloid, respectively. — Pharm. Post, 
Wien, 1906, v. 39, p. 283. 
OLEUM JUNIPERI. 
Henkel, Alice, mentions J uniperus communis L., commonly known 
as juniper, as being common on dry, sterile hills from Canada south 
to New Jersey, west to Nebraska, and in the Rocky Mountains to 
New Mexico. — Bill. Bur. Plant Ind., U. S. Dept. Agric., 1906, No. 89, 
p. 40. 
Kubart, Bruno, (Sitzungsber, Kais. Akad. Wiss. Wien) discusses 
the morphology of the female flower of J uniperus communis L. and 
also points out some of the relations existing between the various 
Coniferse. — Bot. Jahrb. Engler, 1906, v. 37, pp. 45, 46. 
Francis, John M., thinks our revisers have labored under serious 
disadvantages in attempting to outline specifications for juniper oil; 
much of that sold in the United States will not meet the pharma- 
copceial requirements. The tests given will not protect the purchaser, 
who must rely upon the probity of his dealer. — Bulk Pharm., De- 
troit, 1906, v. 20, p. 141. 
Hanson and Babcock report some observations on the oil of Juni- 
perus communis. The oil was obtained in a yield of 0.18 per cent 
and a second distillation of 0.15 per cent. The specific gravity of the
