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 alteraGon 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- 
dies are not soe very impropper for our bodys as some who 
are great friends to domestick ones, & think y' every country 
produces sufficient for y° diseases of its own growth, doe be- 
lieve; & were y' literally true, yet, in this age, w" our diet is soe 
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 Gassistance. Y*imperfectness of physick is much to 
be deplored since its credible y' nature has provided us speci- 
ficks for other distempers, but art has not been yet able to 
discover y™. We have, I confess severall in physick y‘ goe 
under y‘ name, but very undeservedly.

«¢< J", Sydenham was undoubtedly a good observer, a 
faithfull register of all his observa@ons; 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- 
tisor to vary y™ seasons w™ much more latitude y" he doth 
allow. He has been very honest in rescinding from physick
