This Author, after having expatiated a good deal 
upon the different Struftures of the Mufcles, and made 
fcveral learned Obfervations thereon, makes his gene- 
ral ConcluHon to the following Purpofe: 
1. That Arteries, Veins, Nerves, Fibres, and Mem- 
branes are the condiment Parts of a Mufcle: And 
that, though fome Authors have pretended to have 
found Lymphatics, he never could find any. 
2. That there is no Mufcle whofe Fibres do not 
terminate in a Tendon; which are collected either 
into firm Tendons at one or both Extremities, or are 
diffus’d into Membranes, or degenerate into an offeous 
Rigidity. 
3. That thofe very Fibres (which, being clofely con- 
nected together, compofe the Tendon), when join’d 
more loofely, conftitute the Flefh or carnous Sub- 
ftance; and that therefore the Flefh is not a particular 
‘Parenchyma. In which Senfe a Tendon is a continued 
Body from the Beginning of a Mufcle to the End. 
4. That there is fcarce any Fibre in a Mufcle which 
conftitutes a right Line 5 but every one is divided into 
three Lines at leaf, which comprehend two alternate 
Angles. Nor are thefe three always right Lines; but 
often the Flefh, as in the Sphintters, and fometimes 
the Tendons, form curved Lines. 
5 . Thefe three Lines of every Fibre in the fame Muf- 
cle, are not always of the fame Length ; altho’ there is 
fcarce any Difference of Extenfion among them when 
acting all together : That thefe Fibres are in the fame 
Plane; and that, in this angular Order, they form 
oblique- angular Parallelograms , or Rhomboidal Fi- 
gures*;
