The reading of the trench manuscript brought, in by Sr. Robert Moray 

 about taking heights and distances by Catoptric ks was diffcrred till the 

 description of the instrument should come. 



4 Dr. Goddard ' made an experiment concerning the force that presseth the 

 dimensions; and it was found, that twelve ounces did contract 

 .rt of A ire. The quantity of Air is wanting. 



Mv Lord Brouncker was desired to send his Glasse to Dr. Goddard, to 

 make further e\]>eriments about the force of pressing the aire into less 

 dimensions. 



Dr. Wren was put in mind to prosecute Mr. Rook's observations con- 

 cerning the motions of the Satellites of Jupiter. 



Dr. Charleton read an Essay of his, concerning the velocity of sounds, 

 direct and retlexe, and was desired to prosecute this matter; and to bring his 

 discourse again next day to bee entered. 



Dr. Goddard made the Experiment to show how much aire a man's lungs 

 mav hold, bv sucking up water into a separating glasse after the lungs have 

 been well emptied of Aire. Severall persons of the Society trying it, some 

 sucked tip in one suction about three pintes of water, one six, another eight 

 pintes and three quarters, S:c. Here was observed the variety of whistles or 

 tones, which y' water made at the several 1 hights, in falling out of the glasse 

 again.

It uas discoursed whether there bee any such thing as sexes in trees and 

 other plants; some instances were brought of Palme trees, plum trees, hollies, 

 Ash trees, Quinces, pionies, &c., wherein a difference was said to be found, 

 either in their bearing of fruit or in their hardnesse and softness, or in their 

 mcdicall operations: some said that the difference which is in trees as to 

 fertility or sterility may bee made 1 by ingrafting. 



Mention was made by Sr. Rob. Moray of a French Gentleman who having 

 been some while since in England, and present, at a meeting of the Society, 

 discoursed that the nature of all trees was to run altogether to wood, which 

 Wai changed by a certaine way of cutting them, whereby they were made 

 against, their nature to heaiv fruit, and that according as this cutting was done 

 with more or lesse skill, the more or less fruitfull the tree would bee.
