show us the true structure when it could not be certainly inferred from 

 the habitual condition. The author arranges monstrosities under four 

 primary classes ; those of volume, of form, of disposition, and of 

 number. These are divided, the fii'st class into monsters by diminu- 

 tion of volume, {Atrophy^) and by augmentation, (Hypertrophy ;) the 

 second class into monsters by alteration of form, whether irregular 

 {Bifformation) or regular (Pelorias,) and monsters by the transforma- 

 tion of one organ into another, (Metamorphosis;) the third class into 

 monsters by the abnormal connection of parts, or by the disunion of 

 parts habitually united, and into those caused by change of situation, 

 or displacement ; the fourth class into monsters by diminution of num- 

 ber, or abortion, and those by augmentation of number. Under these 

 heads the monstrosities of the ditferent organs of plants are considered 

 in detail, and in a philosophical and very interesting manner. This 

 brief notice of the plan of Moquin-Tandon's work, we are confident, 

 will suffice to commend it to the attention of the botanists of this 

 country. 



9. A Manual of Botany, adapted to the productions of the Southern 

 States ; in two parts : Part I, Vegetable Anatomy and Physiology : 

 Part II, Descriptive Botany, arranged on the Natural System, prece-

 12mo. — The publication of a new local Flora, on the natural system, 

 preceded by a treatise on vegetable anatomy and physiology, embra- 

 cing many of the most recent views and discoveries, furnishes an une- 

 quivocal indication of the advancement of botanical science among us. 

 The first part of this volume comprises, within the compass of about 

 150 pages, a good accoimt of vegetable organogTaphy and physiology 

 in its present state. 



The phenomenon of cyclosis, the laticiferous tissue, the recent views 

 of Endlicher, Schleiden, &c. respecting the origin of the embiyo are 

 all noticed, although the author's limits have often prevented him from 

 entering into sufficient details. To write a flora of any extensive district, 

 or even to prepare a creditable compilation, involves an amount of labor 

 of which few who have not made the attempt can have any conception ; 

 and there are, moreover, several circumstances which just at present 

 render the production of a Southern Flora a difficult undertaking. It 

 will not be surprising, therefore, that we should more highly estimate 

 the first part of this work than the second. We are in doubt, also, as 

 to the geographical limits which the latter is designed to embrace ; since 

 a few plants peculiar to Te.xas and Western Louisiana are included, 

 while perhaps a greater number of published species indigenous to Car-
