30 RECORD OF THE ROYAL SOCIETY 



was referred when the translation of that Italian treatise wherein he handleth 

 of this subject shall bee printed. 



* It was ordered, that, at the next meeting Experiments should bee made 

 with wires of severall matters of y e same size, silver, copper, iron, &c., to see 

 what weight will breake them ; the curatour is Mr. Croone. 



*The reading of the french manuscript brought in by Sr. Robert Moray 

 about taking heights and distances by Catoptricks was differred till the 

 description of the instrument should come. 



* Dr. Goddard 1 made an experiment concerning the force that presseth the 

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

 ^r part of Aire. The quantity of Air is wanting. 



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

 make further experiments about the force of pressing the aire into less 

 dimensions. 



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

 cerning the motions of the Satellites of Jupiter. 



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

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

 discourse again next day to bee enter'd. 



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

 may hold, by 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 up in one suction about three pintes of water, one six, another eight 

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

 tones, which y e water made at the severall hights, in falling out of the glasse 

 again. 



4 Mr. Evelyn's Experiment was brought in of Animal engrafting, and in 

 particular of making a Cock spur grow on a Cock's head. 



4 It was 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 

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

 fertility or sterility may bee made 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 

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

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

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



1 Of Dr. Jonathan Goddard, Aubrey remarks that the Royal Society ' made him their 

 drudge, for when any curious experiment was to be donne, they would lay the taske on 

 him'. ' Brief Lives/ vol. 5, p. 269.
