lined. She conceived, and brought forth 4 young ones. The time she went 

 with young was not exactly known ; but it was believed to be the same as in the 

 bitch. Two of the puppies were like the dog in colour, who had large black 

 spots on a white ground ; one was of a black colour, and the 4th of a kind of 

 dun, and would probably have been like the mother. She took great care of them, 

 yet did not seem very anxious when one was taken from her by the keeper ; nor 

 did she seem afraid when strangers came into the room. Unfortunately these 

 experiments were carried no further ; one being sold to a gentleman, who car- 

 ried it to the East-Indies; and the other 3 were killed by a leopard, one of 

 which I was to have had. The same wolf was in heat in Dec. 1786, and was 

 lined several times by a dog. She pupped on the 24th of Feb. 1787, and had 

 6 puppies, which may afford opportunities, if they are thought necessary, of 

 repeating experiments on this subject. 



While pursuing this subject, I was informed that Captain Mears of the Royal 

 Bishop East- Indiaman, had brought home a bitch jackal with young, which had 

 brought forth soon after his arrival ; and that he had given the bitch jackal and 

 one puppy to Mr. Bailey, bird-merchant, in Piccadilly. I went to see them, 

 and purchased the puppy, the subject of the following experiment, which had 

 dispositions very similar to the half bred wolf which I had from Mr. Brookes 

 before-mentioned. To have a true history of this animal, I took the liberty of 

 writing to Mr. MearSj who politely called on me, and, at my request, set down 

 the particulars in the form of a letter to me, of which the following is a copy.'* 



I took this puppy into the country, and chained it up near a mastiff dog, and 

 they were very familiar, and seemingly fond of each other. When the bitch 

 became first in heat, I could not get a proper dog for her; but the latter end of 

 Sept. being again in the same situation, several dogs were procured, and left with 

 her. They appeared indifferent about her, probably from being in a strange 

 place; and she did not seem inclined to be familar with them; whether the 

 great dog might be able to line her I do not know; she was however twice tied 

 by a tarrier on the 3d of Oct. In a few weeks she was evidently become larger; 

 and on the 30th of November in all 59 days, she brought forth 5 puppies. 

 Some days before this period she dug a hole under ground, by the side of her 



* Sir, — I had the honour of yours the 15th inst. ; and with regard to the female jackal, I can 

 assure you, that she took a small spaniel dog of mine on board my ship, the Royal Bishop. I had 

 her, when a cub, at Bombay ; and a very short time before I arrived in England she got to heat, 

 and enticed this small dog into the long boat, where I saw them repeatedly fast together. I brought 

 her to my house in the countiy, where she pupped 6 puppies, one of which you have seen. Mr. 

 Flaw, at 1S!° 90, Tottenham-Court-Road, has a dog-puppy, which will be at your service at any 

 time you chuse to send for him, to make any fiirtlier experiments : I called on Mr. Flaw, and got 

 his promise to let you have the dog. I have the honour to be. Sir, &c.
