cause different effects as to the strength it receives from the stone; himself 

 having tried all sorts of steel that he could possibly procure, and all the different 

 tempers he could imagine, for the most powerful receiving and retaining the 

 virtue from the load-stone; he also affirms that he has fully satisfied himself 

 that he can infuse such virtue into a piece of steel, that it shall take up a piece 

 of iron of two ounces weight or more; and give also to a needle the virtue of 

 conforming to the magnetical meridian, without the help of a load-stone or any 

 thing else that has received virtue therefrom.* 



Extract of a Letter from Paris y containing an Account of some Effects 

 of the Vransfiision of Blood; and of tivo Monstrous Births. Ano^ 

 nymous. N'* 26, p. 479- 



The blood of a young dog being transfused into the veins of one that was 

 almost blind from age, and could scarcely stir, the latter was obser\'ed two hours 

 after the operation to leap and frisk about. 



Of the two monsters mentioned in this letter, one resembled an ape, having 

 all over its shoulders, almost to its middle, a mass of flesh, that came from the 

 hind part of its head, and hung down in the form of a little cloak. The report 

 was, that the woman that brought it forth had seen on a stage when she was 

 five months gone with child, an ape so cloathed. The aforesaid mass of flesh 

 was divided into four parts, corresponding to the coat the ape had on. This 

 phenomenon was ascribed to the power of imagination. The other monster was 

 a foetus come to maturity, having, instead of a head and brain, a mass of flesh 

 like a liver. It lived four days. There came a letter from Florence, written by 

 Steno, stating that a tortoise was found to move its foot three days after its 

 head had been cut off. 



An Account of two Monstrous Births, not long since produced in De-

One of these monsters was a lamb with one head, but two distinct bodies, 

 and eight legs; the bodies were joined in the neck. It had two eyes and as 

 many ears, in the usual places, and one extraordinary eye in the niddock, with 

 a single ear about an inch behind the eye. The other monster was a lamb with 

 two distinct heads and necks joined at the shoulders, but only one body, and 

 that well formed, yet having double entrails throughout. 



* This seems to be the first notice of making artificial magnets, viz. by this Mr. Sellers, who was 

 probably the same person as the author of the Practical Navigation, first printed in 1669.
