 By James Hodgson, F. R. S. N°443, p. 301. 



Mr. Hodgson's usual annual calculation of the eclipses of Jupiter's satellites: 

 but omitted, for the same reason as before. 



On the Fiper-catchers, and their Remedy for the Bite of a Viper. By William 

 Burton, M.D. at Windsor. N° 443, p. 312. 



William Oliver and his wife called on Dr. B. with their vipers, and either of 

 them offered to be bitten by any viper, and to suffer their arm to swell for 

 some tiuie ; and then, by the external application of a common cheap remedy, 

 in a few hours to remove all the symptoms. Accordingly the experiment was 

 made in the town-hall at Windsor, before Dr. Derham, Dr. Waterland, the 

 physicians, apothecaries, and surgeons of this town, and many other gentle- 

 men of the neighbourhood. The man was bitten in the upper joint of the 

 thumb, and higher upon the same arm, by two different fresh vipers. His 

 thumb, hand and arm soon after swelled much, and all the usual symptoms 

 of a viper-bite followed. He applied the remedy [sallad oil] before us, with 

 the promised success. 



^n Account of the Experiments made June 1, 1734, before several Members of 

 the Royal Society, and others, on a Man, who suffered himself to be bitten by 

 a Viper, or common Adder; and on other Animals likewise bitten by the same, 

 and other Vipers. By Cromwell Mortimer, M. D. Seer. R. S. With some 

 Remarks on the Cure of the Bite of a Mad Dog. N° 443, p. 313. 



William Oliver and his wife, from Bath, who follow the business of catching 

 and selling vipers, offered themselves to be bitten by any viper that should be 

 procured, trusting to the virtue of a remedy they had discovered in trying a va- 

 riety of things, when the woman was once accidentally bitten, and the usual 

 known medicines, even the oil of vipers, had no effect in assuaging her pains, 

 especially of her breast on the same side as the hand in which she had received 

 the wound. This remedy, which is only common oil of olives, and, from its 

 use with sallad, is commonly known by the name of sallad oil, recommends 

 itself not only for its efficacy, but also on account of its being readily to be 

 come at when accidents happen. 



On the 1st of June 1734, in the presence of a great number of persons.
