 or Feathers, at the fame time flic takes care 

 that the air may have admittance through 

 innumerable narrow meanders in fuch quan-

 perfpiring matter. 



I have here, and as occafion offered under 

 feveral of the foregoing Experiments, only 

 touched upon a few of the moft obvious 

 infhnces, wherein thefe kind of refearches 

 may poflibly be of fervice in giving us ufe- 

 ful hints in the culture of plants : Tho' I 

 am very fenfible, that it is from long ex- 

 perience chiefly that we are to expect the 

 moft certain rules of practice, yet it is with- 

 al to be remembred, that the likelieft method 

 to enable us to make the moft judicious 

 obfervations, and to put us upon the moft 

 probable means of improving any art, is to 

 get the beft infight we can into the nature 

 and properties of thofe things which we are 

 defirous to cultivate and improve.
