Quinia to produce a decided antipyretic effect must be given in large quantities. Murchison says that a dose of from fifteen to twenty grains causes within an hour or two a fall of the temperature, and, to a less extent, of the pulse, which may last from twelve to eighteen hours, and that he has never known any other disagreeable symptoms result from its use than noises in the ears, temporary acceleration and irregularity of the respiration, and occasional vomiting. This quantity will often, however, be found to be insufficient to produce a notable reduction of the fever, and it is therefore necessary occasionally to increase it. Liebermeister usually gives to adults from twenty-two to forty-five grains of the sulphate or the muriate of quinia, and this dose must positively be taken within the space of half an hour, or, at the most, an hour, as it is useless, he says, to expect the full benefit of this dose to appear if the dose is divided and its administration is extended over a longer time. He never repeats it in less than twenty-four hours, and, as a rule, does not give it again under two days. Jürgensen has exceeded the dose of forty-five grains without observing any bad effects from it. When these large doses are taken the fall of the temperature usually begins a few hours after the administration of the medicine, the minimum being reached in from six to twelve hours, and it is usually not until the second day that the temperature attains its former height. It is found in practice that the most decided results are obtained when the medicine is given in the evening, so that the time of its fullest antipyretic effects will coincide with that of the morning remission. When these large doses produce vomiting, as they occasionally will, the quinia must be given by the rectum or hypodermically.
Quinia possesses the great advantage over the cold bath that it may be given in conditions in which it would be dangerous to resort to the latter. The existence of great cardiac weakness, of perforation of the bowel, or of intestinal hemorrhage do not usually constitute contraindications to its use. In my own practice I have not often found it necessary to have recourse to much larger doses than those recommended by Murchison, preferring to repeat them if necessary rather than to give a single dose of even half a drachm.
It will be well, in this connection, to allude briefly to a few other remedies which have been given for their antipyretic effect. One of these is digitalis, which has been administered for this purpose in very large doses. Thus, Liebermeister recommends that from eleven to twenty-two grains should be given in the course of thirty-six hours. I have never used this drug in these doses, and therefore cannot speak of its effects from personal knowledge of them. I have frequently had recourse to it, however, in more moderate doses, and I think with advantage.
Another is sodium salicylate. This remedy has been used largely in England and Germany, and to a less extent in this country. It has been claimed for it that it has the power of destroying the germs of typhoid fever, but Stricker100 finds it difficult to accord it this property in the face of the fact that he has had three cases of typhoid fever under his observation which occurred in patients just recovered from rheumatism, which had been treated by this drug. My own experience with it in the treatment of this disease is small, but has been unsatisfactory. While it is undoubtedly an antipyretic, the pulse becomes weak and the inspiration less strong under its use. The brain symptoms do not diminish under its use. Indeed, it is said to produce narcotism in some cases. Dr. Jahn101 and Dr. Jh. Platzer102 speak more favorably of it, but admit that its administration is occasionally attended by the inconveniences above referred to. The verdict of the profession in regard to it, tersely expressed by one who had given it a fair trial, appears to be that it is a remedy that brings nothing but disappointment to the physician and disaster to the patient.

Eucalyptus, in the form of the tincture, is also a favorite remedy with many practitioners. Dr. Benj. Bell103 is in the habit of giving a teaspoonful every three or four hours in a wineglass of water, and asserts that it diminishes the tendency to diarrhoea and the duration of the illness.
