$&§ Improved Pump. — Mefical and Chemical Le&ures, 



pafturage in humid places, although they injure the health 

 of the animals therhfelves, do not impair the beauty of the 

 wool. He had heen called to particular functions elfe- 

 where, which obliged hi p to abandon to the care of in- 

 ferior agents the flock of the pure race kept on his own 

 property. 'I his fiVck has been, for ten years part, managed 

 like all thofe of the department of the Allier, that is to lay, 

 (hut up at nights in clofe narrow (tables, the dung of which is 

 only taken away once a year, and led out at days by children 

 into the moll marfhy pallures, and without any precaution 

 againft epizootic difeafes. C. Rn hard, on returning to his 

 farm, found his (beep in the word polfible (late of health, 

 bat the wool had not, by any means, degenerated; and he 

 has prefented the Society ot Agriculture fome patterns of 

 very fine cloth, which he his caufed to be manufactured 

 with this wool in many of the belt manufactories. Citizen 

 Teiflier had recognized the fame Uct in an experiment which 

 lie had tried at Rambouillet. lie had abandoned, for many 

 years together, a male ana female of pure race, in a meadow 

 very moid and all encom palled with water. Thofe animals 

 had become completely wild ; they took them in order to 

 ihear them with fnares or gins, and, in fpite of fuch a long 

 and untavourable retidence, their wool and that of their pro- 

 geny had not degenerated. 



IMPROVED PUMP. 



We ought to have mentioned in the account of Mr. Bu- 

 chanan's pump, given in the preceding pages, that a model 

 of it is lodged at the Royal Institution.
