useful treatise. Its particular object, the author informs us, is to * 
the student in possession of the results of the numerous and important 
researches which have been published within the last few years in this 
department of science,” especially by the German observers, who are 
prosecuting their investigations in vegetable anatomy with such zeal and 
Success, researches which, scattered as they are through various jour- 
nals, or contained in voluminous works, and toa great extent locked up in 
a foreign and difficult language, are placed quite “beyond the reach of 
many who are interested in them, especially of those whose time is so 
valuable as that of medical students.” | This little work accordingly is 
very valuable as a summary of the most recent views and discoveries 
in vegetable structure, giving special prominence to the formation 
and metamorphosis of tissues, the phenomena of growth, &c. It is not 
a mere compilation, but a careful digest, evidently prepared by one 
who is thoroughly conversant with his subject ; the topics are admirably 
arranged, and the results succinctly and for the most part very clearly 
stated. Without waiting for the concluding part, therefore, we may 
unhesitatingly commend this little treatise to the general, and especially 
to the medical student. Compendious as it is, we know of no work in 
the English language which gives so much information upon vegetable 
_ anatomy. in such a small compass, or so well exhibits the present state 
_ of knowledge and opinion upon this class of topics. A. Gr.

Pyr. DeCandolle, Vol. 5, 1846, (100 plates, folio.) —The fine illustra- 
ted work for which botanists are so greatly indebted to Baron Delessert, 
has just reached its fifth volume. The principal families here illustra- 
ted, are the Lobeliacee, Ericacew and Epacridew, Myrsinacee, Sapo- 
tacew, Styracacew, Apocynacee, and Asclepidacee. The following 
plants of our own country are figured, viz. Dipholis salicifolia, a 
Sapotaceous tree which we believe is found at Key West; Enslenia 
albida, without the fruit ; and Podostigma pubescens. Having recently 
noticed the interesting volites which M. Laségne has devoted to an 
account of the immense herbaria and almost complete botanical library 
of Baron Delessert, we may take this opportunity to state that Prof. 
Alph. DeCandolle has made it the subject of a very instructive review,

and philosophical, and appears to be well adapted to the object
