into the water under the ice, fell into it himself to tlie depth of 1 8 Swedish ells; 

 where afterwards he was found standing upright with his feet on the ground, 

 and whence they drew him up, after he had remained there for the space of l6 

 hours, wrapping him about close with linen and woollen clothes, to keep the air 

 from too suddenly rushing upon him, and then laying him in some warm place, 

 and rubbing and rolling him, and at length giving him some very spirituous 

 liquor to drink; by all which he was at length restored to life, and brought to 

 the queen-mother of Sweden, who gave him a yearly pension, and showed him 

 as a prodigy to divers persons of quality ; the same thing being also confirmed by 

 the famous Dr. Langelot, who himself received the relation in Sweden so well 

 attested, that nothing, says our author, can be required more to prove a his- 

 torical truth. To which narrative are here subjoined some others, so much 

 more prodigious, that we want confidence to insert them here. 



To solve these strange phaenomena. Dr. Pechlinius pretends, that there re- 

 mained in these persons some, though very languid and obscure, motion of the 

 blood and spirits, and that that motion was reduced ad interiora, and there con- 

 fined to a small compass, without circulation. And that it may not be thought 

 impossible that the blood should get into the lungs destitute of motion, our 

 author alleges the life of urinators, in whom it is manifest that there is a mo- 

 tion of the heart and blood, and yet the respiration suppressed, &c.* 



Description of a Hydraulic Engine, from the Register of the Royal Academy of 

 Sciences of Paris, and inserted in the Journal des Sgavans, l675. N° 128, 

 p. 679. 



The effect of this engine is to throw out water to a great distance by the 

 compression of the water forced out through a tube, which turning every way, 

 is thereby fitted to direct the jet of water to the places where the fire is to be 

 extinguished. What is most peculiar in this engine is, that the course of the 

 water, issuing out of the tube that darts it, is continued, not being interrupted, 

 even when the compression of the pump's sucker ceases to act. 



The engine is a chest of copper. A, (fig. 6, pi. 10), transportable by means 

 of wooden bars like a sedan or chair. This chest is pierced above with many 

 holes BB, holding within it the body of a pump EFM, whose sucker DE is 

 raised and lowered by two levers CC, having each of them two arms, so as to 

 be worked by the hands of a man. Each lever is pierced in the middle by a 



* The experiments of modern physiologists have placed it beyond a doubt, that in the case of 

 drowning, man and otlier brea tiling animals are destroyed by the suppression of respiration; in con- 

 sequence of which the blood ceases to be furnished with a principle (oxygen) essential to life,
