but at several times, by which the modes of light produced in the different 

 mediums were the better observable, though no very great alteration happened, 

 either to its colour or vigour, till more than a quarter part of the globe's natural 

 content of air was let in; but sometimes, before half the air was suffered to re- 

 enter, it was not without some pleasure to behold, how the light began to break 

 in branches from that side the globe touched by the hands, filling its whole 

 body with very odd figures; and these branches of light, at the entrance of 

 more air, became more slender, striking then against the opposite side of the 

 glass, and thence reverberating again in a very pleasing manner ; but after more 

 and more air was let in, so the light and figures diminished, till the appearance 

 became the same as in the first trial.* 



Account of what Manuscripts were left by Mr. John Ray ; with some Anatomical 

 ^ i'cObservations made at Padua by Mr, Ray. By Mr. Samuel Dale. N° 307, 

 p. 2822. 



Herewith you will receive some anatomical observations made at Padua, (and 

 contained in the following paper) by our late friend Mr. John Ray, on the 

 dissection of some human bodies, by Signor Antonio Marchetti; and contain- 

 ing besides those things which Mr. Ray himself remarks, divers observations of 

 the operator's which did not occur in those bodies, to some of which Mr. Ray 

 has added notes. To these are subjoined two dissections of Mr. Ray's, viz. of a 

 hare, and the mountain hen. 



Besides these, there are in his Adversaria many observations, inscriptions, 

 epitaphs, antiquities, &c. which being collected together, would make a large 

 supplement to his observations already published. 



Nor must I forget his travels, in our own and the neighbouring kingdom, of 

 which he has left divers itineraries: these may not be unuseful to our English 

 travellers, he being as careful in making observations and collections at home, 

 as he was in foreign countries. 



Observations made in dissecting a Dead Body at Padua. By Marchetti, Dec. i O. 

 1 683, O. S. N° 307, p. 2283. An Abstract from the Latin.-f- 

 After various unimportant observations on the teguments, muscles, &c. 



• In the experiments mentioned in the above paper, we may recognize the beginnings of the 

 phaenomena and doctrine of electricity. 



f Marchetti was professor of anatomy in the university of Padua, at the date aboveraentioned. 

 This account of his observations on a dead body was collected, as above stated, from the posthumous 

 papers of Mr. Ray, who had attended his anatomical demonstrations, and taken notes at the time. It 

 appears that this professor taught many opinions, and advanced many assertions that are extremely 

 erroneous.
