firm pasture-land, of 44- acres: and adjoining to this, apiece of meadow land, 

 of 34 acres. The meadow was lower by a descent of 3 feet than the pasture, 

 and the pasture was lower by 6 feet than the surface of the bog : and there was 

 yet a considerable rising and hill, near the middle of the bog, the height of which 

 was 10 feet above the surface of the bog ; so that there was a descent from it to 

 the meadow. 



A more than ordinary wet spring occasioned a prodigious swelling of the height 

 of the bog at the said elevation, and at length moistened the whole, but chiefly 

 its under part, the water soaking to the bottom. By this means the turfy hill 

 being as it were undermined, naturally sunk down, and consequently pressed the 

 bog on all sides, chiefly towards the descent ; till the pasture was forced on the 

 meadow, overturning the intermediate hedge. 



Observations on different Maladies ; by Mons Gaillard the Son, M. D. of Tou- 

 louse. From the Journal des Sgavans. N° 233, p. 717- 



There was seen 12 years ago, an infant with 1 heads ; one was a sort of a bag, 

 resembling the hood of a benedictine monk, and was fastened to a neck of the 

 same length with the neck of the other head. Being opened, the waters ran 

 out, and the swelling vanished. The neck did not so, that part of it which 

 was next to its original, and which had about the length of 24- inches, was made 

 up of flesh. The child lived 1 5 days. 



Having opened the corpse of a young woman, dead of the king's evil, the 

 glands of the mesentery were found petrified ; most of them were about the size 

 of a walnut, and others of a small nut; in some of them, being opened, were 

 found about a dozen of stones. 



Having opened the corpse of a man in Toulouse, who died of a continual 

 fever, and a spitting of blood, accompanied with a difficulty of breathing, 

 there were found in the right kidney 3 little stones, and some gravel. Going 

 down the ureter, which was much enlarged, the operator found a tough stone 

 of the size of a bean, lodged towards the lower orifice of the same passage : the 

 lungs stuck to the pleura, to the mediastinum, the diaphragm, and pericardium : 

 the wind pipe was full of blood. There was seen in the left lobe, and the 

 back part of the lungs, a bony substance 2 inches long, and \ inch broad : 

 there were 2 polypuses in the heart, one in each ventricle, of the size of a 

 pigeon's egg, whose roots were 10 inches long: the vena cava, both ascending 

 and descending, was covered at its entry into the left ventricle of the heart, with 

 a bony matter. 



Having opened the vena basilica of the right arm of a woman, the operator 

 observed a little black blood that stopped the orifice he had made : and draw-
