in the former we muh always remember, as we muH: alfo fomecimes in

then we may as fafely and eifeutually make ufe of the Bark in the hr ft- as 
we do without difficulty in the other. I hope the Reader will excufe this

The Diet and Air of the Dutch do much contribute to their growing fo* 
plump, and Fat--, and that may be one realon, why they Bleed fo fpa- 
ringly, and feldom as they do. Fo: when they do think fit to Bleed, they- 
will feldom or never take away more Blood from a Man or Woman, 
than we do from zn Infant of -a Year cld. How they came to fall into 
fiich an Extremity of little, I cannot well comprehend, confi- 
dering how profufely the French, and the more Southern Nations, do ufe 
upon moft occafions. Nor are the Dwrrh the moft abftemious- 
from yVme and Brandy, which will be apt to heat and inflame the Blood, 
and Gonfequently upon excefs fometimes caufe Difeafes that properly re- 
quire large Bleedings ; neither am I ignorant that their l:'hjficians are very 
learned Men, and muft read thofe Excellent Books of Galen,, concerning 
VcnefeQion. 
Coughs, that are fo common with us, are very feldom known among 
the Dutch \ infomuch that in the Autumn , when we are deafning one 
another with Continual Coughing, you may go into a Church there, and not 
hear a Angle perfon And for this realon I am induced to think, 
when an Inflammation there falls upon the Dungs , and caufes a violent 
Cough, they cannot fo well deal with fuch a ftrange and foreign Difeafe, 
as thofe who have lefs apprehenfions of Bleeding plentifully when there is 
occafion. 
I have been ask’d fometimes the reafon, why Holland has fo few, or 
No Coughs, and England fo many. The True Reafon I conceive to be 
this : H^Uand has as great a fcarcity of Mineral/, as of Corny of its na- 
tive growth. does abound with Minerals divers Kinds, that 
are very .oflenfive to the Lungs \ howfoever Chymifis may comnend the 
Preparations from them, for other Phyfical ufes. And our Air does a- 
bound with Mineral Effluviums, and much of ©ur vtater with Mineral 
Impregnations This is allb the reafon, whythef/7e oi Sheppey, otherwife 
i Rich Countrey, is fo unwholefome to live in. And this is the reafon, 
why the Waters of the Danube, and other Rivers in Hungary are fo 
unhealthful to drink of. For it was well faid of Pliny, the Great Natura-
