T HIS is one of thofe Chirurgical 
Operations which has many times 
puzzled the mod: skilful Surgeon. Among the Ma- 
chines which Art has invented for the performing of 
it, the Ambe of Hippocrates is one of the moll antient 
and mod famous. 
It is known to confift of an horizontal Lever A, 
and of a fixed Point B. (Tab. II. Fig. 2.) made of a 
Piece of Wood (landing vertically, to the Extremity 
of which the Lever is joined by a Hinge. The Pa- 
tient fitting, and his Arm, that is hurt, being raifed, 
the Machine is pufhed forward under the Arm-pit, 
fo that the vertical Piece of Wood is applied along 
the Ribs, where the Lever enters into the Arm-pit 
up to the End of the luxated Bone, or even farther. 
This Circumflance is effential, and even recommended 
by Hippocrates : Imprimis vero, fays he, id e labor an- 
dum eft , ut ligni fumma pars , brachii capite fuperato 
quam penitijjime alam fubeat. Sett. VI. p. 783. Foefti. 
The Arm is tied to this horizontal Piece, and then 
an Afliftant bears upon the Scapula and the Clavi - 
cula, as is feen in the Figures of Scultetus, Plate 21.
