and every. candidate for the doctorate, as well as every licensed apoth- 
ecary, is required to sustain an examination upon this science. In the 
United States, on the contrary, no medical college within our know- 
ledge, has a separate botanical professorship, or requires any know- 
ledge of the science as a requisite for graduation; and very few, in- 
deed, make provision for a course of botanical lectures! It would not 
be difficult to assign the principal causes of this neglect amongst us, 
of what is elsewhere deemed not only an important, but an indispensa- 
ble branch of medical instruction; but however this may be, we can- 
not believe that such a state of things will be much longer eee

3. Elements of Botany, structural, physiological, systematical, ma 
medical ; being a fourth edition of the Outline of the First Principles 
of Botany ; by Jonw Linptey, Ph. D., F. R.S., &c. &e. London, 
| 1841. pp. 292, Svo.—The first part of this excellent text-book, con- 
. 4 sists of an amplified and corrected edition of Dr. Lindley’s celebrated 
Outlines of the First Principles of Botany. In its original form, this 
f terse and perspicuous statement of the leading propositions of struc- 
a tural botany, having been annexed to the American reprint of the first 
. edition of the Introduction to the Natural System, is well known to the 
botanists of this country ; many of whom, like the writer of this notice, 
derived from it their earliest ideas of the science, and have not forgot- 
systematical- botany, and the alliances of plants, in a tabular form ; the 
latter being an amended translation of the author’s Nirus Plantarum : 
this formed the Key to Botany for the use of Classes, (80 pages, 8vo.) 
published in the year 1835. In the present form, “the whole of the 
structural and physiological part has been corrected with great care, 
and made to include the most important views of modern physiologists, 
So as to present the reader with a view of the state of botanical know- 
» in these departments in the spring of 1841 ;” and the whole is 
very fully illustrated with excellent wood engravings. The second 
Part is devoted to systematical botany, which is defined to be, “ the 
Science of arranging plants in such a manner that their names may be 
_ ascertained, their affinities determined, their true place in a natural 
system fixed, their sensible properties peers of, and their whole his- 
tory elucidated. with certainty and accuracy.” It is principally oceu-
