hours and a half from the commencement of the former; or if not 

 prevented by large doses of the bark. 



No one could do an act more beneficial to society, or glorious 

 to himself, than by teaching mankind how to inoculate this fatal 

 disease, and thus to deprive it of its malignity. Matter might 

 be taken from the ulcers in the throat, which would probably 

 convey the contagion; or warm water might be put on the erup- 

 tion, and scraped off again by tfye edge of a lancet. These ex- 

 periments could be attended with no danger, and should be tried 

 for the public benefit, and the honour of medical science. 



Dr. Harwodd, professor of anatomy, at Cambridge, favoured 



me with the following curious case of this infection: Mr. N 



had a violent delirium in the scarlet fever, with the skin cracked 

 in many places, exuding an ichorous matter; he was attended 

 by a poor man who had recently cut his hand with a glass bottle, 

 and in the struggle of confining him to bed his wounded hand 

 was frequently applied to the patient's body. This happened 

 on the Friday night; his hand was inflamed and the arm swelled 

 the next day; on the Monday following he was seized with the 

 same fever, and died on the Wednesday morning after. This 

 would seem to shew, as far as a single case can be relied on, that 

 the scarlet fever may be communicated, like the small-pox, by 

 inoculation, and probably with similar success, if the matter be 

 diluted with warm water, used in small quantity, and by super- 

 ficial incisions only, through the cuticle. 



12. Miliaria. Miliary fever. An eruption produced by the 

 warmth, and more particularly by the stimulus, of the points of 

 the wool in flannel or blankets applied to the skin, has been fre- 

 quently observed; which, by cool dress, and bed-clothes without 

 flannel, has soon ceased. See Class 1. I. 2. 3. This, which 

 may be called miliaria sudatoria, has been confounded with other 

 miliary fevers, and has made the existence of the latter doubted. 

 Two kinds of eruptions 1 have seen formerly attended with fever, 

 but did not sufficiently mark their progress, which I conceived 

 to be miliary eruptions, one with arterial strength, or with sen- 

 sitive irritated fever, and the other with arterial debility, or with 

 sensitive inirritated fever. 



In the former of these, or miliaria irritata, the eruptions were 

 distinct and larger than the small-pox, and the fever was not sub- 

 dued without two or three venesections, and repeated cathartics 

 with calomel. 



The latter, or miliaria inirritata, was attended with great ar- 

 terial debility; and during the course of the fever pellucid points 

 appeared within the skin, particularly on the soft parts of the 

 fingers. And, in one patient, whom I esteemed near her end,
