1879. | The Origin of the Domestic Animals, 749 
Some authors have derived the dog from the fox. This view 
is not probable, because there exists in the fox a particular dis- 
position which is not found in dogs. 
It is said also that the dog has descended from the wolf or 
jackal. This is possible, but is not probable; wolves and jackals 
do not voluntarily breed with dogs. 
We meet in the quaternary beds and deposits of France with 
the remains of a species of Canidae more nearly allied to the 
domestic dog than to the wolf or fox. But these remains are 
rare, wholly exceptional in our region. If this canid has given 
origin to some one of our domestic dogs, which is possible, this 
could not have occurred in our country. This event happened 
when the quaternary canid was in its own country, where it 
abounded and lived in continual contact with man. 
Among savage animals which may have given origin to the 
domestic dog are found the colson and buansu, veritable wild 
dogs. They actually inhabit the regions of India situated 
between the Lower Himalaya and the coast of Coromandel. 
They are perhaps the emigrated descendants of the quaternary 
canid of which I shall speak presently, and indeed they have 
close osteological resemhJances. 
Our actual races of dogs are so numerous, so varied in form, 
so different that very probably they have had different origins. 
Certainly there is one which has come from the cadéru, the wild 
dog of Abyssinia, which has been found as far as the center of 
Africa. Certainly one of the oldest races of dogs in Egypt is the 
domesticated cabéru. Indeed, on the Egyptian pictures which go 
back to the remotest periods, to the fourth and even to the third 
dynasty, that is to say from 3000 to 4000 years before our era, 
we have seen certain large greyhounds. Indeed, the cadbéru is 
extremely near the greyhound. a — 
But we will not speak farther of the dog. The five other 
domestic animals which we have seen to have appeared in West- 
ern Europe contemporaneously with the polished hatchet and with 
pottery are, the horse, ox, goat, sheep and pig. 
Since all the animals have had quaternary ancestors in our 
region, they have therefore been supposed to have been domesti- 
cated by us. Certain naturalists, indeed, assume that this has 
been the case. An attentive study of facts contradicts this asser- 
tion. The domestic animals appeared all together, contempora- : : -
