they have little need to fetch them from Italy, there being enough 

 in England of the fame kind, not only to fupply this, but per- 

 haps Foreign Nations. Which is all concerning Arts relating to 

 Jione and glafs ; except it be alfo worth notice, that Venerable Bede 

 of this Vniverfity, firft brought Building with/lone, and Glafiwin- 

 dows into England*.

 the Arts relating to Plants; amongft which, the firft that prefent 

 tbemfelves, are thofe that concern the Herbaceous kind. Of this 

 fort we may reckon that ingenious Experiment rmdcm^une, 1669. 

 by my worthy Friend/oi>/z Wills M. A. and Fellow of Trin. Coll. 

 Oxon. in order to find in what meafure Herbs might perfpire, where- 

 in he made ufe of the following method. He took two glafs Vials 

 with narrow necks,each holding ontpound 8 ounces, and 2 drachms 

 of water, Avoir de po'-s weight : into one of thefe glaffes filled 

 with water, he nut a fprig of florifhing 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 window to the Sun. 

 After ten days time, he found in the bottle where the mint was, 

 only five ounces and 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 

 weight, and no mint, he found the Sun had exhaled near one 

 ounce of water, and therefore concluded it drew but fo much out 

 of the firft glafs, 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 pound one ounce 2nd 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 Malpighiws fo wonders at in his Book Be Bombyce, vi^ that 

 thofe Animals willfomtimes eat in one day, more than the weight 

 of their bodies, is out- done by every fprig of mint, and moft o- 

 ther Herbs in the Field,wh'ich every fummers day attraft more nou- 

 riftiment than their own weight amounts too.
