I have been told, that the beft Balfam fC5 Shortnefs of 
Breath is the Balfam of Pem^ which I never faw, u^^^^^'^ 
did I intend to make the above-mentioned Inftrumcnt a Ve- 
hicle tor Balfams, for I freely own, I have no skill of Bal- 
fams ot Gums or Herbs, only this I have often experi- 
enced, that ftinking fmells arc prejudicial to my Lungs* 
I don't defign to invite any body to make ufe of the faid 
Tube, befides I have prefented it to an able Phyfician, who 
is well vers'd in tho(e Balfams, Gums, and Juices, that are 
good for the Lungs. 
That Learned Perfoo, that I mentioned before, fetting 
the Tube to his Mouth, and breathing in the Spirits of the 
Brandy, I told him that we. need not ftop our Nofe when 
we draw in our Breath, but only remove the Tube5 Tab.2c 
Fig. i*DEF from the Mouth.and then Breatliing.to apply 
the Tube again to the Mouth 5 and this one is to repeat fo 
long as one (hall find any benefit by it 5 this Gentleman, I 
fay, was fo pleafed with the Experiment, that he advifed 
me to make it Publick, that the World might be the better 
for it. 
Now in. order to make the Glafs Tube, Fig f.^as ui-eful 
as the other,Fig« 2.1 prepared fuch another Inftrument as is 
reprefented byTab.2. Fig. 3. A B CDEF,that I might place 
the Cork ABCD jnTab.2=,.Fig. i. at A 1,5 and! made this 
loftTumeot or flender Glafs Tube longer than that which in 
Fig, 2. is reprefented by Y Z 3, upon this account, vi%. that 
if one were inclin'd to put more Balfams or Juices into the 
Tube, this long Pipe might be thruft up higher into the 
Water. ' - 
Now if weconfider the Strufture of our Bodies, as far 
as they are known to us, we may iTrmly concludje that no 
part of us is expofed to fo many Evils as the Lungs, for 
how eafiiy may they be hurt if we do but go into the Cold 
Air, which engenders and caufes us to difchcirge Phlegm,
