258 PHILOSOPHICAL TRANSACTIONS. [aNNO 1675-6. 



flowers piit into the receiver changed but very httle, only they looked as if they 

 had been dipped in water. 



Strawberries at the end of two days looked less fresh, but after that, seeing 

 they changed no more in 1 5 days, they were taken out of the vacuum, when 

 they had still the smell and taste of strawberries ; but they had also contracted a 

 very ungrateful taste of the cement used to close them up. At another time 

 some strawberries were inclosed without cement, making use of a skin after the 

 manner described formerly; and then nothing new was observed, except that 

 their taste kept good, but was a little sour, and that they yielded a little 

 water. 



Some cherries inclosed were all burst except two; in two days more they had 

 a little changed their colour, and those two that before remained whole, were 

 now burst like the others. After that no more change in them was observed. 



Having inclosed in the vacuum one cherry with 1 1 large currants, the cherry 

 burst presently, but after that, it changed not, only it appeared turned, as the 

 currants also did. 



Having inclosed in the vacuum four raspberries and three currants, the latter 

 appeared also to be turned, and the raspberries looked less fresh than before. 

 But it is now more than five months, and no change is perceived in them. 



Hitherto had been eniployed only small receivers, which just held the little 

 fruit put in them, and the red currants seemed to keep well enough; so that 

 one day we filled a large glass with them, hoping to keep that as well as the 

 small receivers. But were surprised five days after to see that bubbles were 

 formed in the turpentine, which had been put about the glass, in the place 

 where it was fastened to its cover, and that these bubbles were burst outwards ; 

 and afterwards, having seen that the cover held fast to the bolthead no longer, 

 it left no doubt of the currants having produced air enough to lift up the glass, 

 and to form in the turpentine the bubbles we had seen, and it appeared by the 

 smell that they had fermented. They were yet good, except some that had lost 

 almost all their taste and all their acidity. 



The same thing happened with a very small receiver, that could hold no more 

 than one cherry and one red currant. These fruits yielded also air enough to 

 lift up their receiver seven days after they had been included. This effect is 

 rather to be ascribed to the cherry than the currant. 



Another time we inclosed some of the same kind of cherries, a whole large 

 n-lass full, and found that from the second day they had yielded air enough to 

 lift up the cover. We took away part of the cherries, and inclosed the rest 

 again ; and this second time they did not raise the glass till the eighth day.
