| Description | ' There was put a Mouse into the Compressing Engin, and though four times as much Air was forced into it, as was in it, yet the Animal appeared not to receive any alteration thereby.
Mr Graunt produced a Stone (sent out of Darb-shire) ; but upon Examination, it was found, they were not Screws, but paralell Circles
The same gaue an Account of Sir Wm Petty's new vessell, having suffered a great Storme, in the Harbour of Dublin, where it was riding at Anchor with one onely man in her, who cut her Cable and let her driue a shore, where she bulged a plank ; which when repaired, the Ship would immediately come away for London.
My Lord Brouncker acquainted the Company with the Success of Monsr. Zulichem's Experiment, made by him with Mercury, viz that upon the Exhausting of the Air, the Quicksilver had stood 34 inches high ; and that he had observed, that it never fell but when a Bubble broke ; as also, that when it fell and broke, it fell at once so low, as it would fall by three Suctions. Upon which he was of Opinion that no Account could be given of this Phenomenon from the Equiponderancy of the Air, and consequently the Standard of the Mercury bring about 29 Inches, the rest must be from some other cause.
Mr Boyle did second this Relation, affirming to have made the like Experiment, and found the Quicksilver stand at above 50 inches, and acknowledging that something else must be taken in, to Explicate this odde Phenomenon.
My Lord Brouoncker and Mr Boyle were both desired to prosecute and consider further this Experiment and to giue both the matter of Fact, and their thoughts of the Causes thereof, in writing.
Sir Robert Moray produced a round stone, given in by Mr Godolphin ; who affirmed it to have been broaken out of a Rock . It was recommended to Mr Boyle , to break it, and observe the quality of it.
The same produced also a Mineral, presented him by Colonell Long, in whose ground it was found, smelling like Sulphur, and strongly tasting of Vitriol : which Mr Boyle also was desired to take hence with him, and to examine it.
Captain Taylor mentioned, that there was a Mine in Cornwall, one hundred fathom deep, whereof Colonell Noy, living in that Country, had made a considerable discourse, which by the means of Dr Hoar might be obtained of him. It was ordered that Dr Hoare should be Spoken to, concerning it : as also , that Dr Merrett should be desired to communicate to the Society, what he knoweth of the Oars and Minerals of Devon and Cornwall, and that Dr Cotton should be writtn to by Mr Ball, to get the best information he can concernign the same matter.
The two Iron - balls , one filled with Aurum fulminans the other with Gun-powder, were tryed in a Coal - fire,where that with Gunpowder, fired and gaue some report yet without breaking the Ball, onely making a little crack in it ; but that with Aurum fulminans, did nothing. Dr Goddard was desired, to adde those tryalls to his former account concerning the like Experiments.
Mr Hook's paper concerning the Observables for the making a History of the weather was read and Ordered to be reveiwed by the President and Sir Robert Moray, and then to be Registred and sent unto the several persons that haue been engaged in this work of observing the Changes of weather ; as Dr Power, Mr Beal etc.
The Operator produced 4 of the Thermometers , which he was formerly commanded to provide, and adjust : whereof the President was desired to take one, and Dr Goddard another, to put them into their Cellars, and to observe whether they were warmer in winter than in Summer.
For the adjusting of these Thermometers, it was thought Sufficient, to know what mark they stand at now, and for the making of Observations to take notice, how thereafter, they shall differ from this mark.
Mr Hook was ordered to bring in against next day as Hygroscope, made of the Beard of a wilde Oat with an Index.
Dr Goddard proposed for an Hygroscope the contri-vance of a Lutestring wiith Pulleys and a Cylinder. He was desired to try it .
The same gave some Account of the Variations of the Quicksilver in a glasse case, having observed , that it varieth not according to wet or dry , hot or cold , but according to the thicknesse or clearnesse of the Air , having found it lowest, when the Air was thickset.
Sir Robert Moray promised , to send in at the next Meeting Some Bottles of Water, that had been carried from hence into the East-Indies , and brought back again.
Mr Hill related, that a Ship-master had told him, he had in the Meiterranean drawne some of the water that was grown stinking ([insert in] the Close Vessells) into Tubbs, where having stood exposed to the Air, for 2 or 3 dayes it was grown sweet again and good to drink
Dr Croon acquainted the Company that Dr Pew, who had formerly given them some informations concerning the Pico of Teneriffe, had good hopes of getting a couple of the Embalmed Bodyes of the Guances in the Canary Islands.
Sir Robert Moray mentioned a new way of hatching Pigeons , used by Dr Wallis, and put in writing . Ordered to be read next day .
Mr Boyle presented the Company with a good easy way to prevent Rott in sheep . Ordered to be read also next day .'
