up its forepart. The Fibres of chis Mufcle deftend in a ftreighfc 
Line, till they make up the Body of the Trunk, and then begins 
a ftrong tendinous Interftice, by which they are feparated from 
their Copartners •, whence their Fibres defcend obliquely to ano- 
ther ftrong Interftice, by which on each fide they are feparated 
from their Antagonift, where the lame oblique Courfe of Fi- 
bres is again to be obferv*d, that is to fay, that the Erettcres 
Frobofcidis , (for fo we may call thefe which make up the fore- 
part of the Probofcis) (ggj unite in a tendinous Interftice (cc)f/V 
from whence the Fibres on each fide obliquely defcend : So 
likewife the Retrattores Prolrofcidis * for fo we may call thefe which 
make up the back-part of the Prebofeis, have their tendinous In- 
terlaces running down the middle of its back part •, from whence 
the Fibres obliquely delcend, almoft making an Angle of a De- 
mirbombus on each fide in another longitudinal tendinous Inter- 
ftice, whereby the Fibre* of the antagonift Mufeles are con- 
join’d. 
Thus you fee a wonderful Contexture of 4 Mufcles, fo con- 
triv’d as to perform all kind of Motions j for as either in the Fe- 
mora or Humerm^ from rleftion, Extention, Adduftion and Ab- 
duftion, proceeds a circular Motion ; fo here when the Elevator 
and Deprelfor, .or Retraftor aft together on either fide, then 
there is a lateral Motion : And when the Congener Elevator es and 
Retrattores aft, then there is either Elevation or Deprelfion ^ and 
from thefe two, with lateral Motions on both Sides fuccellively 
perform’d, proceeds a circular Motidn. But this is not all } we 
fee that any part of the Trunk, either Root or Extremity, or both 
at once, can be bended either upwards or downwards ; and this 
I conceive is perform’d after this manner. Thefe Fibres thus 
obliqueiy fituated, are divided into feveral Fafcicuti , which are 
feparated by leveral tendinous Interfeftions ; and that at the be- 
ginning of each Interfeftion, there is a confiderabie Branch of a 
Nerve from the hard Portion, inferred, by which one, two, or 
more of thefe Fafciculi may be fet in Motion, without any other 
part of the Probofcis being concern’d. 
Dr. Moulins , and not unfitly, calls the Probofcis a Prolonged 
Nofe, both from its Situation and life in Smelling and Breathing. 
And I think 1 may with good Reafon make an Analogy betwixt 
it and theTongue : For befides there is a great Affinity betwixt the 
Smelling and T ailing, fince what’s unpleafing to the Nofe, cannot 
but naufeate the Tongue and Palate •, infomuch, that the Nofe may
