 Modern Breeds. In: Amer. Breeders Mag., Vol. III, Nr. 3, S. 174—180, 

 1912. 



There are strong reasons for supposing that the famous Arabian horses 

 were originally the native wild horses of Media and Mesopotamia and that they 

 were there captured and domesticated previous to 625 B. C. The breed was 

 fully established before it was introduced upon the plains of Arabia. That there 

 is a gradual deterioration taking place in that breed of horses upon its new and 

 foreign breeding ground, is proven by the improvement which the Arab is un- 

 dergoing in this country in the hands of out best horsemen. The blood lines of 

 all of the best stock in America trace back to some Arab or Barb.

Heredity charts are given to show the inheritance of deafmutism, feeble-min- 

 dedness and scientific ability. Genealogies are given to show the value of an in- 

 dividual possessing a potentially strong plasm in creating a race of brilliant men 

 and women who have had much to do in raising this country to the position of 

 culture and learning it now occupies. The author makes a plea for the checking 

 of the birth rate of the unfit and the improvement of the race by furthering the 

 productivity of the fit. Pearl (Orono).

 Office. In: Amer. Breeders Mag., Vol. III, Nr. 2, S. 119—123, 1912. 



Advanced students in biology and sociology have been trained in collecting 

 first hand data adequate to the needs of eugenic research. Data on the family 

 distribution of the following straits are being collected: feeble-mindedness, epi- 

 lepsy, insanity, Huntington's Chorea, criminality, juvenile delinquency, vaga- 

 bondism, hare-lip, haemophilia, Cancer, albinism and skin color. All records are 

 indexed according to a system devised by Davenport. The present program of 

 eugenics is research. All schemes for social betterment must be at first experi- 

 mental but the safest experiments are doubtless based on the teachings of the 

 greatest body of facts. Pearl (Orono).

The author states that attention to other eugenic endeavors will be of little 

 avail unless a Crusade to the death upon venereal disease be waged. This agreed 

 upon those measures which will most speedily effect this condition are the most 

 justifiable. Registration, custodial care, restructive legislation against the marriage 

 of diseased persons and the abolishment of prostitution are urged as a means to 

 combat the spread of gonorrhoea and syphilis. Pearl (Orono).
