pean science, which account he received from Baron Von Miiller, 

 who had recently returned from Kordofan. " At Melpis, in Kordo- 

 fan," said the Baron, " where I stopped some time to make my col- 

 lections, I met a man who was in the habit of selling me specimens 

 of animals, and one day he asked me if I wished for an A'nasa, 

 which he described thus: ' It is of the size of a small donkey, has a 

 thick body and thin bones, coarse hair, and tail like that of a boar. It 

 has a long horn on its forehead, and lets it hang when alone, but 

 erects it immediately on seeing an enemy. It is a formidable weapon, 

 but I do not know its exact length. The A'nasa is found not far 

 from Melpis towards the southwest. I have seen it often in the wild 

 grounds, where the negroes kill it, and make shields of its skin.' 

 This man was well acquainted with the rhinoceros, which he distin- 

 guished from the A'nasa under the name of Ferit. This was in 

 April, 1848. In June I was at Knrse, also in Kordofan, where I met 

 a slave-merchant, who was not acquainted with my first informant, 

 and he gave me, of his own accord, the same description of the A'nasa, 

 adding, that he had killed and eaten one not long before, and that its 

 flesh was well flavored." " Herr Rippell and M. Frosnel," adds M. 

 d'Abbadie, " have already mentioned a one-horned African quadruped, 

 and I have with me some notes, which tend to establish the existence 

 of perhaps two different kinds." 



ARABIAN CATTLE. 



ON his return from the Dead Sea Exploring Expedition, Lieut. 

 Lynch brought with him some fine specimens of Arabian cattle, 

 which he presented to the State of Virginia. They are thus described 

 by one who has seen them : " The khaists are respectively eighteen 

 and sixteen months old, the bull weighing 950 pounds, and the heifer 

 650. The bull is 4 feet 10 inches high, and 10 feet 4 inches long 

 from the nose to the end of the tail, and the heifer is of proportionate 

 size. Their limbs are as delicate as those of a gazelle, yet as strong 

 and well-set as those of a race-horse. The heads have something of 

 the delicate outline of those of deer, and their nostrils are thin and 

 flexible ; their feet are broad and flat, and their tails thick and flat at 

 the roots, but they taper down till very thin, and end in a long tuft of 

 silky hair. The color is a deep shining bay, and the horns, which 

 are but just sprouting, are as black as those of a buffalo. They are 

 said, when full grown, to stand 7 feet high, and the milk of the cows 

 amounts to three half-bushels a day each." They are valued at 

 10,000 dollars, and have been presented by the State to Col. Castlernan, 

 who is to take measures to secure the propagation of the breed. 



THE ALPACA. 



WE find in the Complcs Rerulus for Jan. 15, a long paper by M. 

 Geoffroy Saint-Hilaire on the alpaca and the alpa-vigogne, or the 

 mongrel of the alpaca and the vigogne, which latter we suppose 

 to be of the goat species. This paper is supplementary to a for-
