nomena afcribed to electricity; 6th, the magnetic: forée, 
which produces all the phenomena afcribed ‘to magnetifm: 
Confequently all the phenomena of heat, light, electricity, 
magnetifm, according to him, are modifications of the attrac= 
tive and repulfive force of the firft parts of matter, and there 
exifts neither caloric fluid, luminous fluid, ele€tric fluid, nor 
magnetic fluid. This fy{tem has numerous partifans in Ger- 
many, and it has even been extended {till farther. 7th. The 
galvanic force. Humboldt fuppofes that the phenomena of 
galvanifm may be explained by a particular force, which he 
calls the galvanic. Humboldt however always {peaks of a- 
galvanic fluid, as feveral of Kant’s pupils fpeak of the caloric 
fluid, the Juminous fluid, the electric fluid, and the magnetic 
fluid. But thefe are mere denominations, which exprefs the 
unknown caufes of the phenomena of heat, light, electricity,’ 
magnetifm and galvanifm. th. The vital force, vita propria. 
Blumenbach, to exprefs the phenomena of vitality, fuppofes 
a particular force, which he calls vita propria. gth. Ni/us 
formativus. The fame learned man, to exprefs the forma- 
tion of organifed bodies, fuppofes a particular force, which 
he calls ui/us formativus. Jhis amounts to the fame as that 
called by other philofophers the plattic force. 
Barthez believes alfo, that we ought to confider all the 
vital funétions in man and animals, as produced by pecu~ 
liar forees and directed according to the primordial laws of 
a vital principle. “J think I have found, adds he, that 
there exifts in the living mufcles a force of the fixed fitua- 
tion of the molecule and of their fibres (tending to reft) 
different from the forces of contraétion and dilatation (tend- 
ing to motion), the exiftence of which has not been before 
fo much as fufpeéted. The forces of the vital principle are 
inherent in each part of the body which, they animate, and 
exercife there the movements peculiar to, that part. The 
found method of philofophifing in each natural {cience ad- 
mits in them gencral occult caufes *. *
