and again abforb'd into it when it is deficient, ia 

 a Matter of curious Enquiry, and worthy to be 

 induftrioufly fought out by the moft fagacious 

 and dextrous Anatomifts. The Veffels whereinto 

 it is received, and wherein contain'd, are by the 

 Microfcope detedted to be Bladders, and thofe 

 doubtlefs perforated and pervious one into ano- 

 ther ; and tho' for their exceffive Subtilty and 

 TJiinnefs they appear not in a lean Body, yet 

 feerji to have been primitively formed and provi- 

 ded by Nature to receive the Fat upon occalion. 

 Why the Fat is collecfled chiefly about fome par- 

 ticular Parts and Veifels, and not others; as for 

 Example, the Reins and the Caul, I ealily con- 

 fent with Galen and others the Reafon to be, the 

 cherifhing and keeping warm of thofe Parts upon 

 which fuch Veffels are fpread -, fo the Caul ferves 

 for the warming the lower Belly, like an Apron 

 or piece of woollen Cloth. Hence a certain Gla- 

 diator, whofe Caul Galen cut out, was fo liable 

 to fuffer from the Cold, that he was conftrain'd 

 to keep his Belly conftantly cover'd with Wool ; 

 for the Inteftines containing a great deal of Food, 

 there to undergo its laft Concoftion, and no Vef- 

 fels of Blood penetrating it and flowing thro' it 

 to keep it warm, they had need be defended from 

 the Injuries of the external Air by outward Co- 

 verings. Why there fhould be fuch copious Fat 

 gathered about the Reins to inclofe them, i§ not 

 fo-eafy to difcern, but furely there is a great and 

 conftant Heat requir'd there, for the Separatiori 

 pf the Urine from the Blood, the conftant Sepa-
