The indications of the thermometer will show whether the 
affection be of an inflammatory nature or not. Additional indica¬ 
tions and sjmiptoms, as anxiety, vertigo, weakness, etc., will receive 
special mention in another place. Such symptoms which accom¬ 
pany and characterize special affections of the heart will now be 
discussed. 
Acute inflammatory diseases of the heart, pericarditis, myo¬ 
carditis, inflammation of the valves appear, at the outset, with the 
symptoms appertaining to the inflammation. A minute examina¬ 
tion will inform us of the nature and character of the disease. 
The chronic and organic innate affections of the heart are still 
more difficult to determine, but there are certain characteristic 
symptoms, as deviation in pulse, heart-beat and heart sounds, dys- 
pnce, emphysema in horses, increased action of the heart, even 
after a slight exertion, frequent apopletic attacks, vertigo, re 
peated staggering and momentary feebleness, which, however, 
soon disappears, sudden collapse during the performance of work, 
for instance, when a horse is hard ridden, is also observed. Addi¬ 
tional indications are: C} T anotic redness and injection of the visible 
mucous membrane on the eyelids and the vagina, spontaneous 
hemorrhage from the nose, rectum, and vagina, frequent expan¬ 
sion of the visible capillary vessels, especially the veins. Palpita¬ 
tion of the jugular vein is sometimes found united with plethora 
in intense defects of the heart. 
The perceptible symptonfls of the affections of the heart are 
herewith given in general, and now we shall consider the special 
symptoms of the disease, which at the same time offer fulcrnms 
for the. progress, issue and prognosis. 
We are justified in considering as the mildest form of diseases 
such, as are based neither upon organic defects nor pathological 
changes, or inflammatory actions, but result from a momentary 
affection and irritation of the motor, nerves of the heart. Their 
influence upon the action of the heart I will describe later. 
I.—.Neuralgia of the Heart. 
Neuralgic affections of the heart are seldom the object of 
observation in veterinary practice, for subjective fulcrums are 
wanting, because the animal is unable to give utterance to the
