AZOTURIA.

b An abundant nitrogenous diet without overfeeding to the 
extent of impairing digestion, absorption or nutrition. 
c A period of labor which instead of producing poverty or 
emaciation shall bring about a vigorous and robust state of the 
entire body, especially of the nutritive and muscular systems. 
d A brief cessation from labor with more or less completely 
enforced rest extending over a period of one to ten or possibly 
rarely more days. 
e An abrupt termination of the brief period of enforced idle¬ 
ness by labor or other severe exertion, during the first one, two 
or rarely more hours of which the susceptibility to the malady 
is manifest, after which the equilibrium of the system is restored 
and the possibility of producing azoturia ceases. 
In studying the effects upon the physiological state of the 
animal induced by the environments in the sequence related we 
find in : 
a A system prepared for intense nutritive activity, reaching 
beyond the general requirements of the body. 
b A diet fitted to produce a high state of nutrition, especially 
a highly nitrogenous blood supply, abundant in quantity and 
quality. 
c The period of labor intensifies, per necessity, the nutritive 
activity which is met by the abundant food supply, increasing 
the amount of the red blood cells and other nitrogenous constitu¬ 
ents of the blood, muscles and other tissues without augmenting 
in a like degree the water of the blood and other nutritive fluids ; 
a state in the highest sense physiological and capable of indefi¬ 
nite maintenance. 
d The nutritive functions stimulated by the preceding con¬ 
ditions attain a high degree of perfection and acquire what we 
may term a momentum capable of continuation during a shojd 
but not long period of rest with the usual rations, resulting in 
the accumulation in the blood of an unnecessary amount of nu¬ 
tritive material, rendering that fluid still richer in solids and 
comparatively poorer in water, producing a state which we may 
term qualitative plethora, and which, though perhaps perfectly
