N. A. Vigors, Esq. in the Cliair. 

 A specimen was exhibited of a young Nyl-ghau, {Antilope pieta, 

 Pall.,) which was born at tbe Society's Farm in January lašt. The 

 mother of tbis individual bad borne tvvo young about tvvelve montbs 

 since, wbile in the possession of His late Majesty. On tbe present 

 occasion sbe bad also borne tw'o, one of wbicb is still bving. Tbe 

 differences between tbe young and tbe adult animal vvere pointed 

 out. The latter is well known. Tbe former is generally of a dull 

 reddisb favvn colour, wbicb is brigbter on tbe lovver part of tbe legs. 

 A Hne along the belly, descending a short distance dovvn the inside 

 of the legs, together witb a line on tbe fore part of tbe bock, is 

 white. Tbe under iip, a line along its under surface, and a cres- 

 cent-sbaped spot mounting on each side round the base of tbe ]ower 

 jaw, are also vvbite. A spot above tbe front of the eye, and one 

 bebind tbe angle of the mouth are white, as are also the inside of 

 the ears. A black line passes along tbe middle of the nose, and 

 spreading out between the eyes, becomes suffused and lost, From 

 betvveen the ears a black line passes along tbe middle ofthebacktotbe 

 root of tbe tail. A black line passes dovvn tbe front of the fore legs, 

 commencing near tbeir upper part, expanding in front of tbe knees, 

 then contracting, and afterwards dilating again above tbe base of tbe 

 boof, vvbich it surrounds. Above tbe pastern on tbe inner side is a 

 wbite spot ; and tbere is a wbite spot just above the hoofs botb on 

 the outer and inner side. On tbe front of tbe Iower part of tbe 

 hinder legs tbere is a black line, and tbe pastern and feet are black. 

 Above tbe pastern the limb is surrounded in front by a broad balf 

 ring of white ; and tbere are tvvo vvbite spots, nearly uniting in 

 front, above tbe hoofs. The ears at tbeir base for more than balf 

 their lengtb, together witb tbeir extreme tip, are of tbe general favvn 

 of the body becoming mucb lighter tovvards their outer margin : but 

 a broad black blotcb occupies nearly their upper balf, vvitb the ex- 

 ception of tbe extreme tip. The tail is vvbite beneatb, and its tip 

 is black. 



Mr. Cox adverted to the prevalence among Sheep of prolapsus 

 uleri, vvbich be stated to be almost universally fatal to the animals 

 afflicted with it, and for tbe relief of vvbich be pointed out a simple 

 and efficient method. In a sheep suffering from tbis cause be re- 

 rooved the protruded parts by the application of a ligature ; the 

 animal was subsequently turned out to grass, and became^shealtby 

 and as fat as any of the flock vvitb vvbich it was associated. Mr. 

 Brookes stated tbat prolapsus is equally freąuent in some other 

 animals, and gavę the history of a case in vvbich profuse and almost
