“Delirium, and that of the most violent kind, particularly if the patient has arrived at the age of puberty, now takes place, and with all the preceding symptoms of fever, continues for a while to increase, until about fourteen days, often a much shorter space of time, shall have elapsed since the appearance of the symptoms, which were first mentioned in the above detail.
“The disease then undergoes that remarkable change, which sometimes suddenly points out the commencement of what has been called its second stage: the pulse becomes slow but unequal, both as to its strength, and the intervals between the pulsations; the pain of the head, or of whatever part had previously been affected, seems to abate, or at least the patient becomes apparently less sensible of it; the interrupted slumbers, or perpetual restlessness which prevailed during the earlier periods of the disorder, are now succeeded by an almost lethargetic torpor, the strabismus, and dilatation of the pupil increase, the patient lies with one, or both eyes half closed, which, when minutely examined, are often found to be completely insensible to light; the vomiting ceases; whatever food or medicine is offered is usually swallowed with apparent voracity; the bowels at this period generally remain obstinately costive.
“If every effort made by art fails to excite the sinking powers of life, the symptoms of what has been called the second stage are soon succeeded by others, which more certainly announce the approach of death. The pulse again becomes equal, but so weak and quick, that it is almost impossible to count it; a difficulty of breathing, nearly resembling the stertor apoplecticus, is often observed; sometimes the eyes are suffused with blood, the flushing of the face is more frequent than before, but of shorter duration, and followed by a deadly paleness; red spots, or blotches, sometimes appear on the body and limbs; deglutition becomes difficult, and convulsions generally close the scene. In one case, I may observe, the jaws of a child of four years of age were so firmly locked for more than a day before death, that it was impossible to introduce either food or medicine into his mouth; and, in another case, a hemiplegia, attended with some remarkable circumstances, occurred during the two days preceding dissolution.
“Having thus given as exact a history of apoplexia hydrocephalica as I could compile from the writings of others, and from my own observations, I should think myself guilty of imposition on my readers, if I did not caution them that it must be considered merely as a general outline: the human brain seems to be so extremely capricious (if the expression may be allowed) in the signals it gives to other parts of the system, of the injury it suffers throughout the course of this disease, that although every symptom above-mentioned does occasionally occur, and indeed few cases of the disease are to be met with, which do not exhibit many of them; yet it does not appear to me, that any one of them is constantly and inseparably connected with it.”
To this history I shall add a few facts, which are the result of observations made by myself, or communicated to me by my medical brethren. These facts will serve to show that there are many deviations from the history of the disease which has been given, and that it is indeed, as Dr. Quin has happily expressed it, of **LQU]a truly proteiform” nature.
I have not found the dilated and insensible pupil, the puking, the delirium, or the strabismus, to attend universally in this disease.
I saw one case in which the appetite was unimpaired from the first to the last stage of the disease.
I have met with one case in which the disease was attended by blindness, and another by double vision.
I have observed an uncommon acuteness in hearing to attend two cases of this disease. In one of them the noise of the sparks which were discharged from a hiccory[** sic] fire, produced great pain and startings which threatened convulsions.
