latter of which I think it may be reckoned, it seeming to be a species of close 

 earth, of very fine and loose parts, so burnt that it is become black and shining, 

 discolouring the hands, as all the ochres do ; whence the most proper name that 

 can be given it perhaps, is ochra nigra, or black ochre, being a stony sort, as 

 there are stony sorts of the red and yellow ochres as well as clay. 



Account of one Edmund Melloon, (or Malone,) born at Port Leicester in Ireland, 

 who was of an extraordinary Size. Communicated by Dr. William Musgrave, 

 Fel. of the Coll. of Physicians, and R. S. N° 240, p. 184. 



The measures of some of the parts of this Irishman, IQ years of age, shown 

 at Oxford, were communicated to me by Dr. Plot. He was 7 feet 6 inches 

 high ; his finger 64 inches long, the length of his span 14 inches, of his cubit 

 2 feet 2 inches, of his arm 3 feet 2-i- inches, from the shoulder to the crown 

 of his head IH inches. 



On the Dissection of a Dog that had Mercury injected into one of the Jugulars. 

 By Dr. Christopher Pitt. N° 240, p. 184. 



The mercury was thrown out of the blood into the cavity of the abdomen, 

 also some appearance of it in the other cavities of the body. All the glandules 

 were very turgid, and full of liquor, especially in the ventricles of the brain, 

 and all round there was a great quantity of serum. This may be called a true 

 hydrocephalus. It being a chance dog, and having no notice of what had been 

 done on him, I could not so well observe whether it would work on him by 

 salivation, whether it made him duller than ordinary, or how long the quick- 

 silver had been in his body. 



Explanation of the Rubrichs for the Seat of Easter, according to the Julian 

 Account. By Dr. Wallis. N° 240, p. 185. 



The fundamental rule of the Nicene council, which we pretend to follow, for 

 the keeping of Easter, is to this purpose. " Easter day is to be that Sunday 

 which falls upon or next after, the first full moon which happens next after the 

 vernal equinox." This vernal equinox was then observed to fall on the 21st of 

 March; though it now falls on the 11th of March, or sometimes the 10th of 

 March. And therefore instead of " next after the vernal equinox," we say, 

 " next after the 2 1st of March." But then it is said, by a mistake I suppose, 

 " after the first full moon," instead of" upon, or next after the first full moon," 

 (for so it is to be understood,) and added, " and if the full moon happens upon 

 a Sunday, Easter-day is the Sunday after ;" which must needs be a mistake.
