Sec. 229. The Measles have been communicated by [62] Inoculation in some Countries, where it is of a very malignant Disposition; and that Method might also be very advantageous in this. But what we have already observed, with Respect to the Inoculation of the Small-Pocks, _viz._ That it cannot be extended to the general Benefit of the People, without the Foundation of Hospitals for that very Purpose, is equally applicable to the Inoculation of the Measles. [62] The only Account I have read of this Practice, is in the learned Dr. _Home's_ _Medical Facts and Experiments_, published in 1759, which admits, that but nine out of fifteen of the Subjects of this Practice took. Cotton dipt in the Blood of a Patient in the Measles was inserted into the Arms of twelve; and three received the Cotton into their Nostrils, after the Chinese Manner of infusing the Small-Pocks; but of these last not one took, and one of those who had taken, had the Measles again two Months after. We think the sharp hot Lymph distilling from the inflamed Eyes of Persons in this Disease, a likelier Vehicle to communicate it than the Blood, especially the dry Blood, which was sometimes tried; since the human _Serum_ seems the Fluid more particularly affected by it; and this must have been evaporated when the Blood grew dry. A few practical Strictures on this Work, and particularly on this Practice described in it, appeared in the Monthly Review Vol. XXI. P. 68 to 75. _K._ __Chapter XV.__ _Of the ardent or burning Fever._ __Sect.__ 230. The much greater Number of the Diseases I have hitherto considered, result from an Inflammation of the Blood, combined with the particular Inflammation of some Part, or occasioned by some Contagion or Poison, which must be evacuated. But when the Blood is solely and strongly inflamed, without an Attack on any particular Part, this Fever, which we term hot or burning, is the Consequence.
