w" equall success, making noe difference whether y° patient 
be old or young, or y° disease in its beginning, hight, or decli- 
nation, or of w™ temper soever y* patient be, it encounters all 
equally, and I never knew it miscarry but w* we had just 
reason to suspect y* genuiness of y* we made use of, and this 
it performs not by any alteraéén y‘ can be computed to its 
1* or 2° qualitys, as appears by y® insensibleness of any change 
it makes on other bodys not affected w' this distemper. 
Artists have analized it, & by se" changes wrought upon it 
by fire and otherwise have found out much matter of dis- 
course upon its constituent principles, but as to its vertues 
collected from y™ it proves as fallable as other remedys. Tis 
a forrein concrete, & may serve to teach us y* foreign reme-

are great friends to domestick ones, & think y* every country 
produces sufficient for y° diseases of its own growth, doe be-

corrupted w* y* mixture of forrein sawces as wine, spice, & 
other ingredients of luxury, it will be noe strange matter if 
y° diseases y* befall such depraved complexions should not 
obey y* impulse of domestick remedies, but call in forreiners 
to y* aid & assistance. Y*imperfectness of physick is much to 
be deplored since its credible y‘ nature has provided us speci-

discover y". We haye, I confess severall in physick y' goe

««D*, Sydenham was undoubtedly a good observer, a 
faithfull register of all his observa@dns; but it is to be sus- 
pected, he was sometimes a little too hasty in determining y* 
periods of those mo@ons w did constitute y* characterestick 
of y* distemper w™ may be observed by any indifferent prac-
