normal fluid influence exerted upon their cell walls (on exosmotic 
and endosmotic principles). Thus we find in blood flowing through 
an inflamed part, also in the blood of individuals suffering from 
inflammatory fever, a great tendency of the corpuscles to run 
together in firm rolls, and a thin exudative fluid coursing freely 
around them. Wherever we have inflammatory fever we have 
increase of temperature, the result of which is contraction of the 
arterial system, especially the terminal ends of capillary vessels, 
arrestation of the rolls of corpuscles, increase of the watery parts of 
the blood, from checked excretion consequent on the systemic fever 
present, the arrestation of the rolls of corpuscles commencing in 
the inflamed and contracted ends of the lobular capillaries of the 
limp, and the exudation of the serous parts of the blood into the 
surrounding interlobular tissue for relief. The systemic fever, 
whose existence the thermometer indicates in all cases of this 
virulent malady, must also favour those excessive fibrinous deposits 
which so often occur in the inflamed pleurae. For hear what Dr. 
Richardson says in that most interesting article reprinted into the 
Veterinarian for June, 1869, “On the Increment of Animal 
Heat.” “ When by the exposure to air of a high temperature under 
the conditions above named, or when from any other cause the 
temperature of the body itself is increased, a train of symptoms 
follow which are as simple in their character as any in nature, and 
which cover whole fields of what is called medical experience. The 
first sign we observe is the accumulation of heat itself, the fever I 
may most properly call it, in order to retain an old and significant 
name. But the fever is not to be considered as a mere symptom, it 
is truly a symptom, but it carries with it when properly understood 
all the rest of the symptoms. It is primary, the others follow, 
and are dependent on it. Next to increase of heat, and the 
first result, is increase of involuntary motion, motion of respira- 
tion and motion of circulation. This increase of speed in 
the two grand sets of muscles, the prime movers of the 
body, is as much a quick driving from excess of heat as is the 
driving of an engine from heat in the furnace. Thus the pulse 
increases with the increase of heat in the body, both in tension and 
in rapidity of stroke, and it falls with fall of temperature, either in 
tension or rapidity, or both. This excess of motion in many cases 
is of immediate service to the organism ; it is an equalising process, 
it prevents to a marked extent the further increment of heat, it 
employs or uses up the force. 
“ When the accumulation of heat is moderate and slow, the 
increase of motion is frequently succeeded by free elimination of 
water from the body, and here again is a most effective equalising 
agency. Indeed, this process of elimination once started, it is very 
difficult to sustain or advance increment of animal temperature. By 
this process of evaporation we are enabled in the Turkish bath to 
resist those extremes of heat which I have already spoken of as 
endurable. 
“ But when the accumulation of heat is rapid and determinate,
