applying a cylinder of gum-lac near it, it will produce quite contrary effects, 

 viz. precisely the same as gum-lac would produce. In order to succeed in these 

 experiments, it is requisite that the two bodies, which are put near each other 

 to tind out the nature ot their electricity, be rendered as electrical as possible; 

 for if one of them was not at all, or but weakly electrical, it would be attracted 

 by the other, though it be of that sort, that should naturally be repelled by it. 

 But the experiment will always succeed perfectly well, if both the bodies be 

 sufficiently electrical.

 the bed, his head supported by a by-stander, his eyes and teeth fixed, his nose 

 pinched in, his hands, feet, and forehead cold; and all covered with a cold 

 sweat; no pulse to be perceived, and his breath so short as scarcely to be dis- 

 tinguished. Inquiring into the case, Mr. B. was told, that he had been very 

 well all day, and about 8 had eaten a very hearty supper of pork, and a sallad 

 dressed with oil and vinegar; that immediately after he began to find an indis- 

 position; that the sallad consisted of common sallad herbs, bought at a stall in 

 the market, except some celery picked out of their own garden. Suspecting 

 that he had been eating some poisonous herb, Mr. B. asked if he found in the 

 beginning of the disorder any inclination to vomit.' they said no, but that
