|Description|| ' Dr Clark read his Experiments of the injections he had made of severall liquors into the veins of Doggs, for which he received the thanks of the Company who exhorted him to prosecute this matter, and ordered the Account which he had brought in to be registred. [In margin; Fol.]|
Severall reflections were made upon this discourse of Dr Clarke, some observing that any thing thus injected, without preparation and digestion, into the Veins, would make odde Commotions in the bloud, disturb Nature and cause strang symptones in the Body : others suggesting hereupon the Tryalls should be made with such Liquors, as were prepared of such things as has pased the digestion of the Stomack, e.g. Spirit of Urine, of hartshorne, of bloud etc. to see what effects would follow upon them. Some proposed the Experiment to let the bloud of a lusty young dog into the Veine of an old one, by the contrivance of two silver pipes fstened to the veins of such two doggs, with a leather pipe between both to moue the bloud forward, by which means the Extravasating of the bloud might be avoyded. Others added, that these Injections would hardly serue for any medicall uses, but perhaps by filling the vessels of an Animal as full as they could hold, and by distending them exceeding-ly this way, new vessells might be discovered.
Dr Wilkins proposed the Experiment of making a piece of the Skin of one dog to grow upon another. Some things were objected against the probability of the Success thereof, viz How veins, Arteries and Fibres could disseminate themselves, and grow into this strang piece of Skin, patched on ; it being necessary, even to the restoring of a separated part oto the same Animal that there be left some vessells, and that they joyne to one another ; and it being hardly conceivable how the healing can be effected, where the Orifices of the said vessels doe not meet. Others alledged Experience and several Examples of Separated parts healed together again. It was ordered hereuppon, that the Experiment should be first tried, with a piece of Skin, cut from the body of a dog and sowed on again upon the same dog and Dr Croon and Mr Hook were appointed Curators thereof, and the Opertor commanded to provide a dog against next Wednesday.
Mr Hook was also desired to try the growing of hair, and of a Cock's spurr on the head of a Cock.
It was suggested by a letter from Mr Beal, tht it would be worth the tryall to see, what effects would be produced on Plants, put into the Pneumatick Engine with the earth about their roots, and flourishing whether they would not suddainly wither, if the Air were totally taken from them And particularly to try in the Season, Cherry-blossoms when partly opened partly not opened, upon a branch , whether the Air may be so attenuated as to blast ; to which he addeth this Advertisement, tht the blossomes do not forth with discover the blast ; an old experienced Countreyman having once given him notice of a blasty noon (it being then a Sultry weather, and somewhat gloomy with the thicknesse of exhalations, almost like a very thin miste) and within a doay or two shewing the proof upon the Cherry blossoms then flagging, but not much altering their Colour till two dayes more ; It was ordered that this Suggestion should be taken notice of , and the Experiment made in due season.
The Operator was called upon for the Thermometers which the lst meeting he was ordered to provide for this day, to be sent into several parts for the Observation of the weather. They not being ready yet he ws enjoyned to take special care to have them ready against next Meeting.
The same was also ordered to have ready against the nest day a Cylinder of Mercury to be kept in the College, for the observing the Ascent and descent thereof, according to the various constitution of the Air. Dr Croon mentioning that he had found it rise and fall according to the degrees of cold and heat : but with some Air left in the Cane : Mr Hook alledging, that Mr Boyles Cylinder had risen in summer, and fallen in winter, and ascribing this effect to the greater quantity of Vapours exhaled in Summer, causing more gravitation in the Air.
It being again mentioned, that Dr Wren's Scheme for the Observation of all the changes of weather should be sent for by Dr Wilkins ; He alledged that he thought it was left with Mr Boyle, who therefor was ordered to be spoken to, concerning it, by the Secretary.
Dr Glisson should the Company a seal of a certain compounded mettall, of which he said he had herd, tht whenit was soft it would tke off the Impression from any hard wax, and being grown fixed, retain that Impression, and so seve for a Seal. '
