To Lord Cathcart

I am very sorry to find any at new disorder threatening
your Lordship but I cannot yet be much alarmed at what you
mention. I take it for granted that the measure you mention
is English & three pints of Urine from ten at night till 6
next morning does not appear to be large. It is indeed to
be estimated only by a comparison with our drink & liquid
food & even in that view if I consider the milk coffee
wine, water & bark infusion which I think your Lord¬
ship takes, the quantity of Urine cannot be in great excess at
least it cannot be reckoned so till both a more exact
account is taken of the liquid taken in & of the days
Urine as well as of that of the night. I say all this because
I should be averse to proceed to the remedies of Diabetes
while some other remedies ailments remain with your
Lordship and I must go still farther & observe that the
cause your Lordship supposes is not a probable one as I
never knew such an effect in fact nor think it can be
accounted for. I shall therefore wait your Lordships further
accounts before I prescribe much, but I shall not decline
much altogether to offer some advice & therefore say
that a Diabetes is to be obviated chiefly by supporting
& increasing perspiration & therfore by warm cloathing

exercise, by less liquid food & by warm weather
with this I leave your Lordship to judge of your waistcoats
& diet. The infusion of Bark must be continued
for it is often a remedy of Diabetes. I dont think
it necessary to advise avoiding the posture in the night that
is most favourable to breathing & avoiding cough

Whatever change you may think proper to make
in diet I should hardly think it proper to take away
any part of your milk for it is as little diuretic as
any liquid we can employ. The state of our urine
is very unequal & that from slight & transitory
causes
