page 25. Again, in the following page, Siebold by no means asserts, 

 as is implied in the translation, that the life of the female is shortened when 

 impregnation does not take place — a statement which is at variance with 

 the general result of observations on insects. Page 28 — the sac of Psyche 

 helix is described as having one whorl more than is correct, which the figure, 

 as well as the original text shows clearly enough ; page 40, near the foot — 

 stock should be hive, &c. 



These criticisms are, indeed, so minute that we should scarcely have 

 particularized them, were it not that the interest in the subject, awakened 

 by the appearance of this translation into English, insures for it a large circu- 

 lation, as it deserves ; and as that may, and we hope will, lead to further 

 original investigations and fresh evidence of the law propounded, it would 

 not be well to have any pains wasted in controverting particular state- 

 ments with which the author is not, in fact, concerned. A. H. H. 



The Marine Botanist ; an Introduction to the Study of the British 

 Seaweeds, containing descriptions of all the Species, and the best 

 methods of preserving them. By Isabella Gifford. Third Edition. 

 London : Longman and Co. 



This third edition of Miss Gifford's introduction to marine botany is so 

 much enlarged and in every way improved as to deserve to be looked on 

 as a new work. A number of additional plates have been added, and an 

 introductory chapter ; while the systematic portion of the volume has 

 been rendered more valuable by fuller and more accurate descriptions, by 

 additional habitats of some of the rarer species, and by short notices of 

 certain little known species not likely to fall in the way of ordinary col- 

 lectors. The book, in its present form, will be acceptable to many young 

 collectors and amateurs who might be deterred from the study by more 

 formal treatises, and, equally with Dr. Landsborough's little volume, will 

 serve as a familiar introduction to the subject. It is very portable, written 

 generally in a clear style, and sufficiently systematic to answer the pur- 

 poses of system, without being overburdened with technical terms. We 

 heartily wish it the success which it so well merits. W. H. H.
