The liver still did its function of separating the gall : the gall-bladder and its 

 ducts were in a good state: the lobulus spigelii was much enlarged, and crumbled 

 easily like a mass of congealed blood. 



The patient had no particular thirst; nor was there any alteration in the urine, 

 as to quantity more or less. But she had this symptom, common in the hydrops 

 pectoris, of not bearing any other posture than that of leaning forwards on her 

 breast. 



The left kidney, being longer than usual, was examined and found to have 

 two ureters ; and each had its separate pelvis. 



New Observations on Electriaity. By Jo. Henry fVinkler, Gr. et Lai. Literarum

 From the LMtin. 



Hollow glass balls, &c. by the friction of the hand, excite such an electricity 

 in metals and persons near them, that the electrical fire, emitted on the approach 

 of a body void of electricity, bursts out in a continued stream. But when glass 

 tubes are rubbed up and down, the sparks are emitted by intervals. 



M. Winkler describes several machines for conveniently rubbing of tubes, 

 globes, and cylinders of glass, for exciting electricity. And by various ways of 

 increasing electricity, he set fire to several substances, as spirit of wine, &c. 



Description of a Machine to bloiv Fire by the Fall of Water. By James Stirling, 



F.R.S. N°475, p. 315. 



ABCD, fig. 9, pi. 2, is a pit dug in the gi'ound, its surface higher at d than on 

 the other side at A. The bottom bc is strongly rammed with clay, on which are 

 laid thin deals. In this pit is fixed a tub ghki without a bottom, having a hole i 

 at the lower part of the side, and all round thq tub is rammed with clay, except 

 at the hole i. In the middle of the upper end of the tub is fixed a pipe paRS ; at 

 the higher end of which are 4 holes pointing downwards, two of which are repre 

 sen ted by s and r. 



SRTU is a funnel, fixed on the top of the pipe, with a throat xz narrower than 

 the bore of the pipe. In the upper end of the tub towards one side is fixed a 

 crooked pipe at lm, tapering to the end at n. It is made of wood so far as o, 

 but from o to n of iron, the fire being supposed at n. ep is the surface of a 

 plain stone, raised up in the middle of the tub, directly under the pipe pqrs. 



The running water, being let in at the top of the funnel, falls through the 

 pipe on EF, the stone in the tub; it runs out at the hole i, but cannot get off 

 till it rises as high as a. This raises it in the tub almost up to the surface of the 

 stone, and it must not rise higher. So much water must run in at the top of the 

 funnel, as will keep, it always full, or nearly so. This height of water forces it
