Fn order to' give a clear notion of what I mean, 
when I fpeak of the Mufcles of a Cod-fifli, I have 
here caus’d two of thofe Mufcles to be delineated, 
lying clofe together, as they are united to one ano- 
ther, and feparated from the other Mufcles, as is re- 
prefented by A , B , C, £>, Fig. i. the Part defign’d by 
A , J 5 , C, having been cover’d with the Skin near the 
Head of the Fifli. And it is my Opinion, that the 
Body of the God-filh, from Head to Tail, confifis of 
a continued Series of fueh Mufcles. 
I have likewife caus’d a fingie Mufcle of the Fifh

E, H, G, fliews the Thicknefsof the Mufcle j and 
its thin huge, which is no thicker than the Edge of a 
Knife, is marked by E , F , G* 
When thefe Mufcles had lain feveral days upon 
a Paper, yet they were not dry’d fodiard, but that 
I could fplit them into thin Shivers, one of which 
is defign’d in Fig. 3.; between the Letters land K , in 
order to fhew the oblique Courfe of the Fibres, which 
are reprefented by final! Lines. 
I now turn’d my Thoughts to the River-Fifh, and 
particularly to the Pearch j and, as I imagin’d that 
an old Pearch had no. greater number of Mufcu- 
Lar Fibres than a young one, but only that the Fi- 
bres encrcas’d in bignefs during the Growth of the 
Tifh, and that the larger thefe Fibres were, the more 
plain and diftincl muft be the final 1 Velfels, of which 
the Fibres were compofed^ I fent orders, upon a 
Market-day, to bring me the largefl: Pearch that was 
to be found in the Market \ and accordingly, 1 had 
one brought me the largefl that I had ever feen, weigh-
