| Description | Lord Ashely admitted.
' The shavings of Dr Ent's 'Lignum fossils' were committeed to Mr Boyle for Distillation.
Dr Merrets Account of the Experiments of Freezing, made by himselfe, was read; He received the thanks of the Company, and his Discourse waa Ordered to be entered; which yet he desired to keep in his hands, for some little time.
There was also read a Paper of Mr Haaks', upon the same subject; which was likewise ordered to be entered, with thanks to the Author.
It being moved that it might be thought on, to make a Standard of Cold, it was suggested by Mr Hook, that this might be conveniently done, by observing the Degree of Cold, which freezeth distilled water, and by marking thereupon, the Expansion of the Liquor in the Weatherglasse.
Dr Wilkins mentioned, to have raised a heate by a Globe of Ice; and felt the heat of it through gloues, and lighted a Pipe of Tobacco with it.
Mr Hook produced a litle Engine, to make the Ascent and DEscent of Quicksilver in glasse canes more discernable. He ws ordered to prepare against next Meeting, a Tube with Mercury, and fit this Instrument to it.
There were again made some Experiments in Prince Ruperts' Powder-tryer; whereof the Success was, that with Common-pouder, the Ferrell being fixed, the body was raised but a very litle; but with the like quantity of the same kind of Powder, the Ferell being loose; the body was raised to the Top: both which was tryed twice, with very neer the same Effect.
Mr Boyle produed the haed of an Allembeck, with a Substance sticking to the inside of the Glasse, in the form of a Wood, produced from a mixture of Oyle aof Turpentine and Sea - salt, sublimed with a gentle heat.
Dr Goddard desired more time to prosecute the Experiment of Exhausting the Air out of rectified Spirit of Wine.
Sir Robert Moray produced 3 boxes with Poyson, come out of Africa; they were ordered to be left with Dr Goddard till the Presenter shoudl signifie, what they were.
The difference of Eeles being discoursed of , And Mr Henshaw, mentioning the Experience, which the Keeper of the Eel - boat upon the Thames hath of thes Sort of Fish; was desired to make what Enquiry he could of him, concerning their differenc, Food, etc.
Sir Paul Neile mentioned that the Name of the hard Eele was Shaftling.
Mr Lord Ashely mentioned, that he had found Eelesliving in muddy water, to taste ranke, and being put into Spring-water, to get a sweet taste; but with some decay of their flesh.
The Operator was Ordered to provide some Eeles, and to put them into severall Waters; as River-water, Conduit-water etc. to see in which of them they will thrive best.
The same was also ordered, to keep some Fish in Glasses, with water, to observe how they grow there; it being alledged by Dr Wilkins, that 'Rondeletius' kepa a fish in a glasse with water at his howse, which grew so big there, that not onely it cfould not get out at the neck it was put in by, but also wanted roome to move in the Glasse.
The Experiment of Weighing the Air in the Compressing Engine was again made, and agreed very neer with the former; the difference onely being of halfe a Drachme, wherein the weight of the Engine this day, exceeded that of the other; there being now also some greater Condensation of the Air in the Engine than before.
The Operator was ordered to measure how much the Globe of the Engine containeth; and also, exactly to weigh the Engine, before he compresseth the Air in it, and to have the Counterpoyse ready for the Company: it being apprehended, that some of the Engine's weight after the Air hath been let out.
The businesse of propagating Cider fruit, being again Spoken of, the Lord Asheley commended the Redstrake, and especially the Red Redstrake, for yeilding a very rich Liquor, of a long duration, and for being a constant bearer.
Mr Boyle moved, that some of the Redstrake - Cider might be distilled, and the Spirit thereof compared with that of Wine: the Lord Ashley offered a bottle for the Triall.
The Secretary was ordered to write to Sir John Finch concerning the Account he promised to send, of Poysons.
The Operator was ordered to fetch a flight - bow out of Grub - street. |
