by my worthy Friend John Wills M. A. and Fellow of Trin.Coll. 
Oxon. in order to find in what meafure Herbs might ferfpire^ where- 
in he made ufe of the following method. He took two glafs Vials 
with narrow necks,each holding one/'oww^8 ounces^ and 2 drachms 
of water, ^z/oir ^^e weight : into one of thefe glaffes filled 
with water ^ he put a fprig of floriOiing Mint (which before had 
grown in the water^ weighing one ounce ; the other glafs he alfo 
fill'd with water^ and expofed them both in a windorptothe Sun, 
After ten days time, he found in the bottle where the mint was, 
only five ounces znd four drachms of water remaining, and no more, 
fo that there was one pound two ounces and fix drachms fpent, the 
mint weighing fcarce two drachms more than at firft. 
96. From the other Glafs^ where water was put of the fame 
weighty and no mint^ he found the Sun had exhaled near one 
ounce of vpater,, and therefore concluded it drew but fo much out 
of the firft ^/^ys-, at leaft not more ; So that allowing one ounce for 
what the Sun had exhaled, there was in thofe ten days fpent by 
the mint^ one pound one ounce fix drachms of water ; and the mint 
being increafed in weight only two drachms^ 'twas plain the mint 
had purely expired in thofe ten days, one found one ounce znd four 
drachms^ that is, each day above an ounce and half which is more 
than the weight of the whole mint. Whence he concluded, that 
what Malpighim fo wonders at in his Book ^e Bombyce^ viz^ that 
thofe Animals willfomtimes eat in one day, more than the weight 
of their bodies^ is out- done by every /^r/^ of rnint^ and moft o- 
ther Heiibs in the Fie/^^, which every fummers day atcrad more nou- 
ridmient than their own weight amounts too.
