Kindred: Inheritance of Pit in the Ear

INHERITANCE OF PIT IN THE EAR THROUGH -FOUR GENERATIONS 



The propositus in this case is No. 7 in the third generation. Her grandfather (I, 1) was the 

 first known to have the pitted condition. He transmitted it to his son (H, 2), father of the pro- 

 positus. He (H, 2) passed it on to four of his children as shown in the third generation. Two 

 others of the third generation, not possessing the pit themselves, transmitted it to individuals 

 in the fourth generation. It may also be seen that HI, 7 did not transmit the condition to the next 

 generation, but that HI, 9 did. (Fig. 18.) 



A New Study of Eugenics 



The Trend of the Race: a study of 

 present tendencies in the biological 

 development of civilized mankind, 

 by Samuel J. Holmes, Ph.D., pro- 

 fessor of zoology in the University of 

 California. Pp. 396, price $4 net. 

 New York, Harcourt, Brace & Co., 

 1921. 



Never before have the data of 

 eugenics been subjected to such a 

 thorough criticism as by Dr. Holmes. 

 Entirely in sympathy with the princi- 

 ples underlying the eugenics movement, 

 he has made a valuable contribution to 

 it by his exhaustive treatment of the 



literature, particularly that from Eu- 

 rope. His conclusions generally accord 

 with those accepted by other eugenists. 

 The book is lacking in careful defini- 

 tions of the terms used, and makes 

 little attempt to suggest remedies for 

 the various dysgenic trends noted. 

 After a few introductory chapters on 

 inheritance, and on the birth rate, it 

 is devoted almost wholly to a con- 

 sideration of the various selective 

 influences at W'Ork on mankind. It is 

 announced that a full bibliography of 

 the subject is to be published sepa- 

 rately.— P. P. 



For and Against Birth Control 



The Control of Parenthood, edited 



by James Marchant, introduction 



by the Bishop of Birmingham. Pp. 



222. New York and London, G. 



P. Putnam's Sons, 1920. 



Every intelligent person favors birth 



control — in one sense or another; but 



most intelligent persons reprobate the 



birth-control propaganda which has 



been a glaringly unscientific treatment 



of a biological subject. In this volume 



the problem is discussed by J. Arthur 



Thomson, Leonard Hill, Dean Inge, 



Harold Cox, Mary Scharlieb, F. B. 



Meyer, A. E. Garvie, H. Rider Haggard 



and Marie C. Stopes, some being pro, 

 some being contra, and one or two 

 apparently "on the fence." The vol- 

 ume probably presents the sanest and 

 most thoughtful discussion of the 

 subject that is available, although the 

 rhapsodical views of Dr. Stopes on 

 "maternal impressions" hardly belong 

 in a serious book. While nothing new 

 is presented, the facts and arguments 

 on both sides are brought forward in a 

 w^ay that should stimulate any responsi- 

 ble person to do a good deal of thinking, 

 if his mind is not already closed on this 

 topic. — P. P.
