the upper part of the arm, near the deltoid mufcle 
(which was ftill very large near the biceps ) and the 
cxtenfores cubiti , two deep hollows ; and the exten- 
sion of the elbow was made with great difficulty : 
wherefore I touched him chiefly upon thofe mufcles 
which cover the upper part of the arm, having in- 
creafed the electrical power in Mufchenbroek’s man- 
ner; for he feemed to come on but flowly while the 
ffiocks w r ere but mild. But I made the neceffary 
difpofitions to hinder his being at the trouble of lift- 
ing up his arm to touch the tube ; I applied it to the 
hand and arm where I judged neceffary j and, on the 
23d following, he was able to lift and carry a weight 
of fixteen pounds and an half. 
I repeated the operation on the 23d, 24th, and 
25th. He was extremely fenfible of the flighted: 
fhocks on the laft day, fo as to excite compaffion in 
all that were prefent. Befides which, during the time 
that his arm was electrifying, I obferved certain pro- 
tuberances in thofe places, from whence I drew the 
fparks, like thofe which profeffor Jallabert had feen 
in his patient ; but in thefe two days they became 
very large, and, upon rubbing the arm, the fkin 
peeled off: notwithstanding they diminiffied on the 
following days, altho’ the fhocks were made more 
powerful ; which is the more remarkable. The del- 
toid mufcle, which, on the 2 2d, was obferved to be 
So large, became much lefs ; and the hollows, which 
were between this and the biceps and extenfors of the 
elbow, were filled up ; but, upon bending the elbow, 
there remained ftill a preternatural rigidity. 
On the 27th, the patient gave feveral proofs of the 
advantage he had gained by the electricity, in the pre-
