17 6 Mr. Pafchal to Mr. Ray. 



P. S. Lately reading Mr. Lewengh Observation of 

 Scales in our Skin, it gives me occafion to refleft up- 

 on the wifdom of Nature, in providing for the regu- 

 lating of Tranfpiration. That the circumferential 

 preflure may not hinder it too much , Fifties (in their 

 Elements) need a ftronger and larger Scale than we

This Hypothecs its learned Author applies in his

 siderable 5 but that I could not do with my greateft 

 Diligence. W. D.

 the Beauty or Decorum of the Work 5 let the Un- 

 dertakers look to that. As for thefe Catalogues, I 

 have promifed them, and they have accepted, and 

 I muft be as good as my Word. I have already fent 

 up thofe from Cornwall to Kent, and have received 

 a Letter of Thanks from Mr. Gibfon, who manages 

 the whole Work for them, and feems by his writing 

 to be a good Scholar* and ingenious Perfon : So that
