bility of the Trunk of the Body 5 that the feveral 

 Vertebres (hould be fo elegantly and artificially 

 compacted and join'd together, that they are as 

 ftrong and firm as if they were but one Bone \ that 

 they (hould be all perforated in the middle, with 

 a large Hole for the fpinal Marrow or Pith to 

 pafs along, and each Particular have a Hole on 

 each fide to tranfmit the Nerves to the Mufcles 

 of the Body, to convey both Senfe and Motion ; 

 that by reafon of the fore-mention d clofe Con- 

 nexion of the Vertebres, it fhould be fo form'd as 

 not to admit any great Flexure or Recefs from a 

 right Line any angular, but only a moderate cir- 

 cular bending, left the fpinal Pith fhould be com- 

 prefs'd, and fo the free Intercourfe or Paffage of 

 the Spirits to and fro be ftopt. 



One Obfervation relating to the Motion of 

 the Bones in their Articulations I fhall here add, 

 that is, the Care that is taken and the Provifion 

 that is made for the eafy and expediate motion of 

 them, there being to that purpofe a twofold Li- 

 quor .prepared, for the Inundion and Lubrifica- 

 tion of their Heads or Ends. i. An oily one, 

 furni{l:i'd by the Marrow. 2. A mucilaginous, 

 fupply'd by certain Glandules feated in the Arti- 

 culations, both which together make up the moft 

 apt and proper Mixture for this Ufe and End 

 that can be invented or thought upon 5 for not 

 only both the Ingredients are of a lubricating na- 

 ture, but there is this Advantage gain'd from their 

 Compofiiion, that they do mutually improve one 



another \
