["A very old and active correspondent," _Tim Tobykin_, has furnished
us with the following interesting extracts from Dr. Rennie's
_Treatise on Gout and Nervous Diseases_, just published. These,
however, are but a portion of our correspondent's selections; and as
they are written in a popular style and appear to be equally
applicable to the welfare of all classes, they will doubtless be
acceptable to our readers. We are not friendly to the introduction
of purely professional matters into the pages of the MIRROR, but the
following extracts are so far divested of technicality as to render
their utility and importance obvious to every reader.]
