ever rapidly he may be moving. The animal furnishes the 

 principal meat eaten by these Indians, while its skin is work- 

 ed into rugs and robes. 



The wood of which the Moqui boomerang is made is ob- 

 tained from the crooked branches of a species of walnut, pro- 

 cured by the barter of sheep, corn, etc., from the Navajoes, 

 who own the' locality (the canon of Chelly) in which it is 

 found. 



More recently the same weapon has been detected, accord- 

 ing to a communication to the California Academy of Sci- 

 ences, among some of the tribes of the California Indians ; 

 and it is possible that further investigation will show a still 

 more extended use of it among the Indians. 12 A, August

ORIGIN OF THE DOMESTIC DOG. 



Professor Jeitteles, in continuation of his very elaborate 

 memoir upon the prehistoric antiquities of the city of Olmutz 

 and its surroundings, discusses the character of certain cra- 

 nia of the dog family coming under his observation. He 

 considers that the wolves of the present day represent only 

 three species Canis lupus, Canis lycoides, and Canis saca- 

 lius. The Canis lupus is the wolf of modern times, and has 

 two races, one in the Old World and the other in the New. 

 The second form has two sub-species, which he calls lupaster 

 and gracilipes. To the first of these belong the small wolf 

 of the Pyrenees, the wolf of the steppes of the Ural and Volga, 

 the wold-dog of Africa, the dingo of Australia, the Canis ho- 

 dophylax of Japan, and even the prairie-wolf of North Amer- 

 ica ( Canis la-trans), as also the dog of the bronze period, 

 which is the first indication of the taming of any species of 

 wolf. The second sub-species he calls gracilipes, referring to 

 it the jackal of Senegal. This he considers to be the ances- 

 tor of the greyhound. To the third species, Canis sacalius, 

 the author refers the jackal of Algeria, Farther Asia, and Eu- 

 rope, and considers this to be the ancestor of the dog of the 

 peat-bogs. The modern races, known as the shepherd dog 

 of Eastern Europe, the greyhound, the fox-hound, and the 

 poodle, are all considered as having a very close relationship 

 to the dog of the bronze period. The very great resem-
