In another feries of experiments the fame philofopher ex- 

 -hibited the phaenomena of the gveatefl; excitability refuUing 

 from the appHcation of the Galvanic conduftor. ift, Towards 

 the medulla oblongata of the head of a warm-blooded animal 

 recently feparated from the trunk. 2d, On the trunk itf^lf. 

 3d, On the head and trunk; at the fame time makins: the 

 anus on the one hand, and the ear on the other, communi- 

 cate with the Galvanic battery. A fmall quantirv of blood 

 fcattered over the table contributed, no doubt, to the energy 

 of this fimultaneous contra£lion of the two parts placed at a 

 remarkable diftance from each other. 4th, On a portion of 

 the mufcles detached from the body of the fame animal. 



5tb. The crural nerve of a frog, brought into contart with 

 one of the mufcles of the warm-blooded animal, exhibited 

 evident figns of contraftion. 



6th. The heart of the fame warm-blooded animal, placed 

 in a veffel and fubjetled to the impreffion of ihe galvanic 

 battery, gave no figns of excitability. This, indeed, is one of 

 thofe organs which are fooneft decompofed afier the death of 

 the individual. 



The members of the fociety paid the utmoft attention to 

 all thefe experiments; and the prefident, C. Nauche, congra- 

 tulated in their name C. Aldini on the manner in which he 

 had conducted them, and the zeal he had fliown tofupport, 

 by new fa6ts, the theory of his illuftrious uncle Galvani. 



From thefe facts it feems to refult, lit, Thai ihe animal 

 fluid fupplies the place in analogous experiments of the elec- 

 tric fluid propagated by metals. 2d, That this animal fluid 

 has 110 need of any other conductor than the organized parts, 

 3d, That the nerves and the mufcles are the furelt conductors 

 of this fluid; and, confequci\tly, that experiments tried either 

 on the nervous plexus or the origin of the nerves mull pre- 

 fent the moll (Iriking and decilive effeds. 4th, That the 

 different met ds, in whatever manner applied, in cafes ana- 

 logous to thofe in quellion, perform no other fuiidions than 

 that of favouring, more or le(s, the propagation of this uni- 

 vtrfal fluid, which penetrates eafily, and in preference to all 

 others, the nervous and mufcular parts of organized bodies.
