" Hayward's Botanist's Pocket-Book. " Eevised by G. 0. Druce,

More than a generation of field botanists have found this little book 

 a most useful companion on their rambles, serving to remind them ol 

 what to look for and to refresh their memories concerning the chief 

 points of distinction between species. Much progress has been made 

 smce its first issue, and none has done more in aiding it than the 

 reviser of the present issue. Further, the adoption of the " Vienna 

 Eules ' ' has led to the alteration of a considerable number of the names 

 that were familiar to us in the older floras. These alterations are 

 unfortunately necessary before finality can be reached, and it is to be 

 hoped that all botanists will loyally accept the opinion of the Vienna 

 Congress, although they may not think all its findings strictly logical. 

 All the British species and their varieties are entered with the exception 

 of those in " critical genera " such as Rubus and Hieracium, and 

 for the difficult forms of these the botanist is referred to standard 

 w^orks. Indeed, no good purpose would have been served by giving 

 brief descriptions of these critical forms, such as is given of all the 

 other plants. The general plan of the older book is closely followed, 

 the botanical and common names, habitat, colour, growth, duration, 

 and time of flowering being arranged in columns on one page, and brief 

 characteristics of species and varieties on the opposite one. The field 

 botanist, whether a novice or a veteran, will find this an indispensable 

 companion on his rambles. Its size is such that it will readily slip into 

 the pocket. 



"Gleanings from the Fields of Nature." By E. J. Connold, 

 F.Z.S., F.E.S. 8vo., xvi. + 270pp. (Eeligious Tract Society, London, 

 1908.) 3s. 6d. 



This is another of the books, now so numerous, designed to show 

 what to see in country and seaside rambles. A variety of natural objects 

 are drawn upon to form texts for the author's interesting notes, from 

 the sea-urchin and the humble-bee to the primrose and the yew. The 

 book is well got up and fairly free from technical words. The illus- 

 trations are particularly worthy of note, especially a beautiful photo- 

 gravure of a fruiting shoot of yew ; the primroses on plate 13 , the oak 

 on plate 22, and the mealy Guelder rose on plate 23 are also very 

 pleasing.

This book commences with a most lucid and interesting account 

 of the early history of manures, giving due prominence to the important
