On the Cure of the Hydrophobia. 25 1 



7th, That they can manifeft themfelves by means of a 

 chain eftabUihed between two points of the fame nerve, and 

 by adtki<?lion in organs brought into contaft with fome part 

 of the flefn. 



Vaflah-Eandi has given interefting obfervations on gal- 

 vanifni. " We do not yet know," fays he, " what is the 

 caufe of thefe extraordinary phenomena : Volta is incHned to 

 beHeve that the mufcular contraftions are excited by the 

 elcftricity vihich the metals that touch each other, or the 

 heterogeneous bodies that ferv'e as, conduftors, acquire ; and 

 that, confequently, we fee no animal eleftricity in the phe- 

 nomena of galvanifm; which, according to this theory, 

 proves nothing elfe than that animals are eleftrometers more 

 fenfible of the fmalleft degree of eleftricity than other elec- 

 trometers." The author then relates the experiments of 

 thofe who afcribe all thefe phenomena to an ele6lricity pe- 

 culiar to animals; and he concludes by faying — " Were I 

 to declare my opinion, I fhould be inclined to believe that 

 the mufcular contraftions are produced by the movement of 

 animal eleftricity directed by the conductors of natural elec- 

 tricity." The changes of ele6tricity which different fluids 

 experience in the botly, may ferve to explain thefe pheno- 

 mena; for he himfelf has proved, for example, that urine 

 when iffiiing has negative electricity, while the blood which 

 flows from a vein has pofitive ele6tricity. 



Fabbroni has publiflied an important work on fevcral phe- 

 nomena afcribed to oalvanlfm. Inftead of afcribing the ef- 

 fe6ts to eleftric fire, he is of opinion that they depend on a 

 chemical operation ; that is to fay, an aftion exercifed by the 

 two metals on each other. (See Fhil. Mag.. Vol. V. p. 268.)
