o The pectoral muscles were in little better state, than those of the abdomen; 

 nor were the intercostal muscles like those of the limbs. I am apt to think all 

 the muscles employed in respiration, had more or less of this blackish appear- 

 ance. The right lobes of the lungs were diseased; and the same side of the 

 thorax had a small quantity of serum in it. The lungs on the other side were 

 in no bad condition. The heart was very flaccid and large : the right ven- 

 tricle and vena cava had a small polypus in them. The vena pulmonaris was 

 exceedingly dilated next the basis of the heart. The left ventricle of the heart 

 had a small polypus, and had a great quantity of grumous blood. The great 

 artery was very thin, and appeared not a little extended, and had some cartila- 

 ginous bodies interspersed in its membranes. 



In the head; the dura mater was found inseparable from the cranium in its 

 upper part. A polypus was drawn out of the upper great vein of the brain, 

 called sinus falcis superior. The carotid arteries were very thin, and much 

 larger than they ought to be, before they entered the substance of the brain. 

 In short, all the blood-vessels, which I examined, were very much dilated, and 

 seemed to be charged with as much wind as blood. 



^n Account of a Hail Storm, near RotJierham in Yorkshire, June 7 i i 7 1 1 • By 

 Mr. Ra. Thoreshy, F.R.S, N° 335, p. 514. 



The storm of hail, accompanied with terrible thunder and lightning, hap- 

 pened the 7th of June last (1711) '- it began about Rotherham, where it burnt 

 a noted tree. About 1 o'clock it reached Wentworth Woodhouse. The hail- 

 stones were from 3 to 5 inches in circumference, and some say larger, which 

 killed several pigeons; but the chief damage done here was to the glass windows. 

 In Washfield, about two miles from thence, it did vast damage. Some part 

 of it escaped, and the barley received no damage; but the generality of the 

 wheat was cut off, about half a yard from the ground, and the rye about two 

 feet. The stubble, though green at first, turned white, so that it looked like 

 a field newly shorn. Great quantities of twigs and small boughs were beaten 

 off the trees, which being of less moment are omitted; but the damage in the 

 corn was severe on the poorer sort of inhabitants. 



Microscopical Observations on the Contexture of the Skin of Elephants. By Mr. 

 Leuwenhoeck, F.R.S. W 36, p. 518. 



On observing the roughness of the skin of an elephant, and being told by 

 the keeper that it fell off every year, I prevailed on him to scrape off a little of 

 the said skin on a paper. On viewing the particles, I always imagined that the
