Another question occurs: What is the milk that merits preference? In answer to this, I will not enter into an examination of the various sorts of milk; this would be over-lengthening my work by an adventitious subject; for satisfaction in which there are many recourses extant, and perhaps none better than a dissertation, now indeed out of print, of the late Mons. d’APPLES, M. D. and Professor of Greek and Morality in this College[107]. Now-a-days there are hardly any kinds of milk used but of the female breast, or of asses milk, the goat’s, or the cow’s. Each has its different qualities: it is the comparison of these qualities, and of the indication presented by the disorder, that should determine the choice from among them. There are few cases in which milk from the cow may not be succedaneously used for all the others. That from the female breast is generally believed the most strengthening: it is the notion of the greatest masters in the art, and yet this opinion bears upon a ruinous foundation, which is, the women’s making use of animal food, without considering at the same time that the preference is constantly given to the milk of a hale robust nurse from the country, who eats no flesh-meats, or, at least, very little, and who lives only upon bread and vegetables. I believe, however, that there are cases in which it may be tried with success. The noble cures operated by the use of it, leave no doubt of its efficacy; but there is one inconvenience which is peculiar to it, which is, that it must be taken immediately from the breast that furnishes it: this is a precaution, of which GALEN has already taken notice of the necessity, and, in ridicule of those who would not care to confine themselves to it, he refers them “_like asses, to asses milk_.” But in the case of recourse to the female breast for lactation, might not the vessel of conveyance excite those desires which the main point is to keep under? Might it not expose the patient to the temptation of renewing the adventure of that Prince, the story of whom CAPIVACCIO has preserved to us? He had two nurses given him, whose milk produced so good an effect, that he put them both into a condition of supplying him, at the end of some months, with new milk on a fresh account, if he should happen to need it.
