THE QUARTERLY REVIEW OF BIOLOGY 



which intelligence makes for itself a 

 vehicle in the physical organism. The 

 deductive argument exhibits this process 

 as a part of a vaster and more significant 

 evolution. But the strength of the posi- 

 tion is that, so far as the two arguments 

 cover the same ground, they coincide in 

 the main lines of their teaching." 



TRAVELS IN SPAIN AND THE EAST. 



1808-1810. 



By Sir Francis Sacheverell Darwin. 



The Macmillan Co. 

 $z.4o 5 x 7I; ix + 12.1 New York 



Sir Francis Sacheverell Darwin was the 

 sixth son of Erasmus Darwin. In 1808 

 he set out from Birmingham to see the 

 world with Mr. Theo. Galton, Francis 

 Galton's uncle, and three other compan- 

 ions. This book is his diary for the next 

 two years. It is delightful reading. 

 They had plenty of adventures, and saw a 

 great many interesting things in a trip 

 which took them as far east as Constanti- 

 nople. Of the original party one is robbed 

 and murdered on the road, soon after 

 they land in Spain; a second goes to the 

 bottom in the Viper between Cadiz and 

 Gibraltar; a third joins the army and is 

 killed on the retreat to Corunna. Finally 

 Mr. Galton gets the plague in Malta and 

 dies, Mr. Darwin staying with him to the 

 end. 



The book is a welcome addition to 

 Darwiniana and Galtoniana. 



Cambridge Comparative Physiology series 

 covers, in greater detail, similar ground to 

 that reviewed in The Quarterly Review 

 op Biology in the articles by Professor 

 Crew which appeared last year. The 

 material is discussed under the following 

 heads: The mechanism of sex-determina- 

 tion; the physiology of sexual differentia- 

 tion; sex-reversal in the adult individual; 

 the mode of inheritance of sex-dimorphic 

 characters; and the sex-ratio. There are 

 very extensive and complete bibliog- 

 raphies. The book will be extremely 

 valuable as a reference source for the 

 development of knowledge up to the 

 present time in what is just now one of the 

 most lively fields of biological research. 



THE HARVEST OF THE YEARS. 

 By Luther Burbank with Wilbur Hall. 



Houghton Mifflin Co. 

 $4.00 5^x8; xxvi -f- Z96 Boston 



Essentially an autobiography of an 

 interesting human being, though largely 

 written in actual fact by Mr. Hall after 

 Mr. Burbank's death, but with the aid of 

 copious notes which he had left. Every 

 student of genetics will be interested in 

 reading this volume, particularly between 

 the lines. It is illustrated with some 

 twenty odd photographs, chiefly portraits 

 of Mr. Burbank and his friends. The 

 book is a fine record of a useful life. It 

 lacks an index.
