tlie three upper molars is 7*5 millitn. as compired with 6*2 iu 

 T. europcea, and of the lower 8"1 as against 6'8 ; the breadth 

 of m^ is 3"0 as against 21, and of m.2 2*0 against 1-3. The 

 difference in the height of unworn teeth is equally striking. 

 Second lower molar with a small supplementary external 

 basal cusp at the bottom of the valley separating the main 

 cusps; last molar with a slight indication of the same cusp, 

 which is not found in Talpa earopce.i or ccpxa ; although very 

 possibly not constant, its presence is noteworthy. 



Dimensions of the type (measured iu skin) : — 



Head and body 126 millim. ; tail 29 ; hind foot (s. u.) 19. 



ISkull : greatest length 3G'7; basal length 31"6 ; zygo- 

 matic breadth 15; mastoid breadth 17*t^; interorbital breadth 8; 

 palate, length 16"2, brealth outside m^ 11"1, inside m^ 4-7.

This mole, by its powerful teeth, is lenarkably ditTerent 

 from all its allies, and it is most surprising that it has not 

 been distin^-uished before.

This little book should prove a useful guide to the difficult art of 

 photo- micrography. Coimnoncing at the very beginning of the 

 subject, the reader is led by gradual steps onwards until the 

 photography of such minute objects as bacteria is reached. The 

 first part of the book is devoted to the actual process of taking the 

 photograph, the second to developing the negative, printing, and the 

 preparation of objects. The apparatus employed is fully described, 

 and directions are given for its home-manufacture, together with a 

 number of practical "tips," the outcome of the author's experience. 

 The directions given for the preparation of objects are necessarily 

 brief, but are, perhaps, sufficient for the beginner. A concluding 

 chapter deals with stereo-photo-micrography, and the advantages of 

 this neglected branch are emphasized.
