LITERARY AIDS. 53 
Peckolt, ‘* Catalog der pharmacognostischen, pharmaceut- 
ischen und chemischen Sammlung aus der Brasilianischen 
Flora.” Zeitschrift des Allg. ssterreichischen A potheker- 
Vereines, VI. (1868), 518. Extended pharmacognostical essays 
by the same author are to be found in the periodical mentioned. 
Representations and descriptions of drugs may be found, 
although for the most part very deficient, in the various com- 
mentaries to the pharmacopeias, and in the manuals of the 
practice of pharmacy. 
J. An exhaustive work on the History of Pharmacognosy, 
based upon an adequate study of sources of information, is still 
wanting. In the circle of German literature the following are 
worthy of consideration, however, in this respect: 
Meyer, “Geschichte der Botanik,” 4 volumes, Kénigsberg, 
1854-1857. This work has, indeed, remained uncompleted, 
since it extends only to the last quarter of the sixteenth century, 
but nevertheless includes the periods which, in many respects, 
are the most interesting for the history of pharmacognosy. 
Jessen, ‘‘ Botanik der Gegenwart und Vorzeit in culturhisto- 
rischer Hinsicht,” Leipzig, 1884. This work supplements the 
last named, and contains, notwithstanding its brevity (495 
pages), a large amount of substantial information, although 
pharmacognosy does not properly fall within its sphere. 
Hehn, ‘‘ Kulturpflanzen und Hausthiere in ihrem Uebergang 
aus Asien nach Griechenland und Italien, sowie in das iibrige 
Europa,” fourth edition, 1882. 
Sigismund, ‘‘ Die Aromata in ihrer Bedeutung fir Religion, 
Sitten, Gebriiuche, Handel und Geographie des Alterthums bis 
zu den ersten Jahrhunderten unserer Zeitrechnung,” Leipzig, 
1884, (Reviewed in the supplement to the Pharm. Zeitung, 
Bunzlau, May 31st, 1884, p. 377.) 
A. de Candolle, “‘ Origine des plantes cultivées, Bibliothéque — 
scientifique internationale,” Paris, Germer Bailliére & Co., 
1883. 
K. A Bibliography of Pharmacognosy is also still want- 
ing. The beginning of such a work is presented in Pereira’s 
** Elements of Materia Medica,” II. (1857), 833-869. Some
