Obfervations on Animal Eleétricity. 145 
and with a certain degree of violence, fometimes my.arms, 
and fometimes my feas: Under thefe circumftances the 
electricity was thrice changed from — to +, and 16 times 
from 0, or weak +, to—. On my fervant, under the eas 
circumftances, it was eight times changed from + to — 
and on my maid five times fronr — to +. 
13. Everyother motion of the body, not connected with Roh, 
violence, or with uncommon agitation of the limbs, when it 
does not produce much fatigue, does not impede pofitive ani- 
- mal electricity. 
14. Such motion is no impediment alfo to negative animal 
| electricity. ; 
_ 15. After noon, or dinner-time, animal electricity is not 
_ greater thah common. 
8 16. The ufe of coftee makes no change in animal electricity, 
17. Continual {training of the thoughts is not only favour- 
( able to pofitive animal eleCtricity, but increafes it in an un- 
- common degree. 
_ 18. Animal electricity is impeded by perfpiration. 
_ ‘Ig. Animal eleétricity is {tronger in winter than in fummer, 
20. Repofe at noon, or any other fhort fleep when fitting in 
’ the day-time, does not difturb pofitive animal electricity. 
; 21. The breath does not conduct animal electricity in a 
mee pele manner, I breathed on the cover of the condenfer 
in various places, but I never found the leaf traces of elec- 
‘tricity. The eleétricity, in all probability, was difperfed too 
‘fpeedily, or was too fubtile to be perceptible. 
22. Bodily motion is by no means neceffary for seagate 
animal eleétricity; 
23. Neither does it depend on the movement occafioned 
by refpiration. 
24. Animal electricity arifes alfo without frifion of the 
elothes, My experiments leave no doubt on this fubject; as 
T found the electricity on my own body lively and durable for 
half an hour, or an hour, when I had on no clothes. Ido 
not fay, however, that the friction of the clothes does not 
jnereafe it. 
» 25. Animal eleétricity is excited without any friGtion of the 
external parts of the body. 
26. There is alfo a {pontaneous kind of animal electricity,
