"This is, lor tlu' purposes of t'xaet science, uniioubtedly a valuable bool;. . . . As ri'<;anls llif 

 highest niauniial, man. it is well pointed out tliat the sense of touch lias been from the veiy lirst of 

 extreme importance, and that 'such use of this sense in man must have contributed greatly to 

 his better e(|uipnient for the struggle of his life, and thus in a broad way have been governed by 

 a slow, remorseless process of selection.' The Viook is eminently one for specialists, but the 

 excellence of the numerous illustrations makes it also inteiesting to the general reader." — Liniilrui

"Dr. Kidd's book is the most important contribution to the matter since Miss Wtiiiiple's jiapei-

■' 8uch a book as this is calculated, at least, to give pause to the Weismainiians. Ur. Kidd has 

 broken ground in a commanding position, and we are anxious to .see how bis attack can be met." 

 — Vka Irish Naturalist. 



"This is an interesting contribution to the dynamic or I amarckian principles of evolution. . . . 

 The author seems to have made out a good case and to ha\e been led by the legitimate use of the 

 inductive method to what seem to be valid and natural conclusions." — .S'eicnce. 



" It is urged that . . . the doctrine that acquired characters are never inherited does not hold 

 good, and hence a Lamarckian explanation of the phenomena nui.st be accepted. The ai.se, as 

 argued l)y Dr. Kidd, appears to be a strong one, and it will be curious to note what the Weisman- 

 nists will have to say in reply." — Kiwvleilge.

" Dr. Kidd shows much ingenuity in explaining the various causes which, in his opinion, have 

 j)roduced the ditferent hair-slopes, and the illustiations with which the book is liberally furnished 

 are of considerable assistance to the readei." — Wistiiii iisti r Jiiriiw. 



" The description of the facts can be commended. I'here is evidence that considerable care has 

 been taken in the collection of observations, and the illustrations are excellent." — Manchester 

 Guardiitn. 



" That the direction of the hair-slope in mammals varies nnich is a fact well known to zoologists ; 

 but we are not ac(|nainted with any general work, such as the present, in which the f.icts are put 

 together within one cover. The author has, therefore, in any case, acconi]ilislied a piece of work 

 which supplies a delinite want in the literature of zoology. The usefulness ol this general summary is 

 furthermore enhanced by numerous clear ligures which .sliow at a glance the essential facts."— Aance/.
