which I have accustomed myself.
You know the cold bath has long been in vogue here as a tonic; but
the shock of the cold water has always appeared to me, generally
speaking, as too violent, and I have found it much more agreeable
to my constitution to bathe in another element, I mean cold air.
With this view I rise almost every morning, and sit in my chamber
without any clothes whatever, half an hour or an hour, according
to the season, either reading or writing. This practice is not in
the least painful, but, on the contrary, agreeable; and if I return
to bed afterwards, before I dress myself, as sometimes happens, I
make a supplement to my night's rest of one or two hours of the most
pleasing sleep that can be imagined. I find no ill consequences
whatever resulting from it, and that at least it does not injure my
health, if it does not in fact contribute much to its preservation. I
shall therefore call it for the future a _bracing_ or _tonic_ bath.


_On the Causes of Colds._

_March 10, 1773._

**** I shall not attempt to explain why damp clothes occasion
colds, rather than wet ones, because I doubt the fact; I imagine
that neither the one nor the other contribute to this effect, and
that the causes of colds are totally independent of wet and even of
cold. I propose writing a short paper on this subject, the first
moment of leisure I have at my disposal. In the mean time I can
only say, that having some suspicions that the common notion, which
attributes to cold the property of stopping the pores and obstructing
perspiration, was ill founded, I engaged a young physician, who is
making some experiments with Sanctorius's balance, to estimate the
different proportions of his perspiration, when remaining one hour
quite naked, and another warmly clothed. He pursued the experiment
in this alternate manner for eight hours successively, and found his
perspiration almost double during those hours in which he was naked.


_Dr. Stark_[38].

_May 4, 1773._

**** The young physician whom I mentioned is dead, and all the notes
which he had left of his curious experiments are by some accident
lost between our friends Sir John Pringle and Dr. Huck (Saunders);
but these gentlemen, if the papers cannot be recovered, it is to be
presumed, will repeat the experiments themselves ****

the same with that, which, being attracted by, and entering into other more solid matter, dilates the substance by separating the constituent particles, and so rendering some solids fluid, and maintaining the fluidity of others; of which fluid, when our bodies are totally deprived, they are said to be frozen; when they have a proper quantity, they are in health, and fit to perform all their functions; it is then called natural heat; when too much, it is called fever; and when forced into the body in too great a quantity from without, it gives pain, by separating and destroying the flesh, and is then called burning, and the fluid so entering and acting is called fire.
