Fig. i. i, 2, 3/4, fhew the Forms of feveral mufcular 
Fibres, confiderably magnify’d by the double Micro- 
fcope, where they appear to differ in Size, as well 
as in the Number and Diftance of their Cells > as 
it is mentioned in their Defcription before. 
Fig. 2. is a View of feveral mufcular Fibres, with 
thofe minute Blood-veffels which I have called the 
Tar die l or Capillary Canals (fee Led. II. Seffi. 
XVI. and XVIL) lying in their parallel Dire&ions,. 
in order to anfwer the Ends of Nature ; which 
are explain'd in the Courfe of that Ledlure. 
Fig. 3. is a Reprefentation of the Circulation of the 
Blood in a little Piece of the Mytulus> not ex- 
ceeding a Quarter of an Inch every way in its na- 
tural Dimenfions ; wherein it appears, that thofe 
minute VefTels are in a Direction parallel to other 
Fibres of whatfoever Nature. 
Fig. 4. fhews Part of a Capillary CanaU with Part 
of a Mufcular Fibre on each Side; to demonstrate 
how the minute Twigs are fent off from the Canal 
to the mufcular Fibres to nourifh them, as is hinted 
in the iaft Scdlion above-mentioned. This is 
view’d by the greateft Magnifier of the double re- 
flecting Microfcope*
