372 PHILOSOPHICAL TRANSACTIONS. [aNNO 1747, 



tract of bark with musk were ordered. But the hiccup increased, watry blisters 

 appeared on the scrotum, the voice faultered, the head failed, and the pulse 

 sunk. He became worse and worse, till he quietly expired on Sunday morning 

 at 11 o'clock. 



On dissection, they found the scrotum and corpora cavernosa penis mortified ; 

 the ossa pubis wrenched asunder to the distance of 4 inches, and a rent in the 

 bladder, half an inch in length, a little above the neck, and exactly in the middle 

 where the ossa pubis join. This was a very astonishing sight, and gave quite a 

 new idea of the case; which if any physician could have discovered without in- 

 spection, he must have had more penetration than Dr. C. pretends to. We may 

 now, however, reason about it, with a little more certainty than before; and it 

 seemed that the body of the horse in twisting, acted with the power of a lever, 

 to which the suddenness of the jerk, added in some measure the force of per- 

 cussion. But all this leaves us still in wonder at the effect; for Dr. Greene was 

 a very strong large boned man, 64 years of age, and the uniting surface of the 

 ossa pubis was considerably broader in him, than either the surgeon, or Dr* C. 

 had ever seen in any subject. 



On the Difference of the Degrees of Cold markedly a Thermometer kept Within 



Doors, or IVithout in the Open Air. By the Rev. Henry Miles, D. D. 



N" 484, p. 6l3. 



By an extract from Dr. M.'s register of the weather, is shown the state of his 

 barometer and thermometers, for some days of the same week, in which is ob- 

 served a sudden change of the temperature of the air, particularly on Thursday 

 morning the 3d ; by which may be seen the little use a thermometer is of, 

 when kept within doors, to determine the state of the air abroad, as to heat 

 or cold. 



Dr. M. had 1 thermometers filled with mercury, and of the same construc- 

 tion, made by the late Mr. Sisson. The one was placed without his chamber 

 window, in a north-east position, under cover, contrived to admit a free passage 

 of the air, but to keep off sun and rain; the other within the window, about 

 3 feet from the former, where the sun never falls on it; the room is constantly 

 occupied as a bed-chamber, but had no fire in it that season. 



It appears that on Tuesday the 1st, at 8 in the morning, the thermometer 

 without stood at 17 degrees above O, or freezing point; that within at 14. 

 At 9 at night, that without was at O, and that within at 12 above 0. So that 

 in the space of 13 hours the former had fallen 17 degrees, the latter only 1. 



As the barometer had been for a good while past subject to sudden consider- 

 able variations, he suspected the severe cold on Wednesday night and Thursday 

 morning would not continue long; accordingly, on observing the thermometer
