testicle was out of its natural place, drawn up above the aponeurosis or 

 hole of the 3 muscles of the abdomen, which gives passage to the spermatic 

 vessels that go to the testicles in men, and to the round ligament of the matrix 

 in women. The bladder was extremely distended, and full of urine. In the 

 stomach was a worm of about Q inches in length, and a line and half broad, as 

 also a kind of slimy matter : the liquor contained in the stomach was black ; 

 but whether it had its colour from some remedies prescribed against his vomiting, 

 or was the effect of some disease, cannot be determined. In the 2d cavity, the 

 lungs were united to the pleura on the right side, but were free on the left ; in 

 the left there was an inflammation of the pleura, with some matter, as also an 

 inflammation of the external tunic of the lungs. In the heart was a large 

 polypus, in the left ventricle, which filled the vena pulmonaris, and entered the 

 left auricle, about 8 inches in length, and 2 fingers broad. In the right ven- 

 tricle, there was also a polypus, of about an inch in length, and so large that 

 it almost stopped the entrance of the blood into the vena cava ascendens. In 

 dissecting the brain, we found also a considerable polypus in the sinus longi- 

 tudinalis ; all other things were according to nature. From what is here ob- 

 served, it is easy to conjecture the cause, both of his vomiting and of his 

 sudden death. 



On the Nature and Differences of the Jukes of Plants. By Dr. Martin Lister, 



F.R.S. N°224, p. 365. 



An abstract of the only useful parts of this long paper, comprises the follow- 

 ing observations. 



Dr. Lister observes, that mostly juices coagulate, whether they be such as 

 are drawn from the wounds of a plant, or such as spontaneously exude; and 

 vet even that exudation seems to be often accidental, that is, by canker, or 

 some similar chance. 



That among those juices which coagulate and are clammy, there are some 

 which readily break with a whey. In the middle of July, he drew and gathered 

 the milk of lactuca sylv. costa spinosa, C.B. and of all our English plants, 

 that he has yet met with, this most freely and plentifully aftbrds it. It springs 

 out of the wound thick as cream, and ropes, and is white, and yet the milk 

 which came out of the wounds, made towards the tOp of the plant, was plainly 

 streaked or mixed with a purple juice, as though one had dashed or sprinkled 

 cream with a few drops of claret. And indeed, the skin of the plant there- 

 abouts was purplish also, perhaps with veins. Again, when drawn into the shell, 

 it turned still yellower and thicker, and by and by curdled, that is, the white 

 and thick caseous parts separated from a thin purple whey. So the blood also of
