Blectric fenomena of organisms 
For electric fenomena of muscles see 612.743, of nervs and muscles 
see 612.813 
Theory of electric fenomena 
Negativ variation 
Electrotonus ‘ 
Electric fenomena of tissues in repose and in action 
Action of electricity on organisms 
Everything concerning effect of electricity on function may be clast 
here by adding 0 and dividing like 612; e. g. action of electricity on 
red corpuscles 612.0144240111, as .III is the subdivision of 612 
meaning red corpuscles. Action of electricity on bile 612.0144240357, 
as .357 means bile

Poisons and chemic substances 
Poisons and definit chemic substances ar preferably clast in 615.7, 
general toxicology in 615.9. This number is for topics of special physi- 
ologic interest 
Effects of water 
Reviviscent animals 
Hydrations 
Quantity of water in organisms and tissues 
Physicochemic forces 
Osmosis

Physiologic effect of X rays 
To express effect of X rays on a specific organ or tissue, ad o and 
subdivide like 612; e. g. effect of X rays on sight 612.0144811084 
Effect on lower organisms 
Effect of radioactiv substances; Becquerel rays 
Production and action of N rays
