The bones forming the roof of the skull have

The bones forming the roof of the skull have, however, been highly vascular loaded with dark blood so that if dried they become of almost a black hue; and without disputing the accuracy of either of the authorities I have mentioned, these appearances to my mind account more satisfactorily for symptoms which no one asserts ever border upon phrenitis. The brain seems to me to be only sympathetically affected, not absolutely involved in this disease. When this is threatened, there is generally some notice given before the fits, succeeded by stupor, are displayed. The eye will sometimes brighten, and the discharge from the nose will cease. This, however, is by no means constant; as it is not rare for both to continue, or even to become more copious; but if one only should remain, the nose is certain to be the part whence the deflexion will issue. No positive dependence, therefore, can be placed upon the discharges from the eye or nose. The eye, nevertheless, is certain to denote that which is on the eve of happening. The pupil may be small; and when it is so, its decrease of size will be marked, and it will have little disposition to enlarge. This, however, is rarely witnessed. Generally the pupil is much enlarged, so much as to conceal the iris, and alter the character of the organ. The eye is moreover retracted, and the dog has a very peculiar expression of mingled pain and stupidity. If the hand be placed upon the head, it will be sensibly hot. No matter how thick the coat may be, the heat will be apparent, and the carotid arteries will sensibly throb. The coat feels dry and is warm, although the animal may be trembling to such a degree as prevents the pulse being counted. Yet the dog seems lively; it is active now, though perhaps a little while ago it was dull; every trivial circumstance now attracts its notice. The appetite is generally ravenous. The dog which only the day before was disinclined to feed, is suddenly disposed to eat more than it ever was known to consume; and it will gnaw and swallow the hardest wood for want of better provender. The amended appetite is mostly one of the symptoms, but it is not invariably witnessed; for occasionally increased activity, and the strange appearance of the eye, are all that indicate the approach of fits. It will not be long, however, before something shall be added which is more definite in its meaning. The dog which was running about suddenly stands still, and begins to smack its lips and champ its jaw. It keeps stationary while doing this, and continues so until a quantity of froth and thick saliva falls from the mouth, drops upon the ground, and then the action ceases. The animal looks around with a vacant stare, evidently not conscious where it is, and starts away, hitting itself perhaps against anything which may oppose its progress. If caught it struggles to get loose, and may even bite the hand which, when conscious, it would perish to defend. Almost immediately, however, it regains its faculties, and then seems quite as well as it appeared to be before the attack came on. It may continue subject to be thus seized for several days; or soon after the first attack, fits or convulsions may start up. During the champing colic may set in, which will only yield when the fits are established. The duration of the champing is not regular; it may be only for a few moments, or for several minutes. The attacks may be no more than one or two in the day, or twenty may occur in a single hour. Generally they remain about three days, but here also there is no rule. I have known them to be present for a week, and also to exist only for a few hours. In these latter cases the condition of the dog is generally not understood. It is taken out for a long walk, or it is indulged with a hearty meal; and in the middle of the one, or shortly after the other, it begins to champ, utters a loud sharp cry, which is suddenly cut short as if the animal was choked. The eyes glare, the mouth is open, and before perfect insensibility ensues, the dog bites at every object near it, then falls down convulsed, the limbs stiffen, the head is drawn back or twisted to one side, the urine and dung are voided; and a slate of unconsciousness, which may cease in a few minutes, or continue for hours, during which the body is in contortions, and the saliva flows freely from the mouth, stretches the poor brute upon the earth. When this is over, the dog recovers as from a trance, being always disposed to ramble, and should its strength permit, will start away at its utmost speed. There is neither to the number nor duration of these fits any limit; they may be few or frequent, and long or short. The second may end the life; or every five minutes, nay oftener, they may occur, and the animal survive for days. Any excitement will bring them on, and the passage of the fæces invariably is accompanied by an attack. Diarrhœa always begins when they commence, and the dog soon loses strength, and lies upon its side unconscious and incapable of motion; the pulse is not to be felt, and gradually without a struggle it expires. Let no man, however, be hasty in saying positively when death has taken place. Often has the life seemed gone, for the heart has been still; but minutes afterwards the animal has gasped, and then began to breathe once more. Death, however, comes at last, for if the dog sinks to such a state, I have never known it to revive.
