_A farther account of an Observation above-mentioned, about _White Blood_._

Since the Printing of the former Sheet, there is this farther account from the same hand.

Mr. _Boyle_,

I have at length, according to your desire, received from the Ingenious Dr.

_Lower_, an account in writing of the Observation about _Chyle_ found in the Blood; which though you may think strange, agrees well with some Experiments of his and mine, not now to be mentioned. The Relation, though short, comprizing the main Particulats of what he had more fully told me in Discourse, I shall give it you with little or no variation from his own words. {118}

A Maid, after eating a good Break-fast, about seven in the Morning, was let Blood about eleven the same day in her Foot; the first Blood was receiv'd in a Porringer, and within a little while it turn'd very white; the last Blood was received in a Sawcer, which turn'd white immediately, like the white of a Custard. Within five or six hours after, he (the Physitian) chanced to see both, and that in the Porringer was half Blood and half Chyle, swimming upon it like a Serum as white as Milk, and that in the Sawcer all Chyle without the least appearance of a drop of Blood; and when he heated them distinctly over a gentle fire, they both harden'd: As the white of an Egge when 'tis heated, or just as the _Serum_ of Blood doth with heating, but far more white. This Maid was then in good health, and only let Blood because she never had her Courses, yet of a very florid clear Complexion.

Note.

_The _Reader_ of these Papers is desired, that in those of _Numb. 4. pag.

60. lin. 10_. he would be pleased to read _eight_, instead of _hundred_: this latter word having been put in by a great over-sight, and without this Correction, injuring that Author, whose Considerations are there related.

This Advertis.e.m.e.nt should have been given in _Number 5_. but was omitted for haste._
