L ANIMALCULA OF INFUSIONS. ^'j 



in fome winters at Peterlburgh, the thermometer 

 fell 29°, and once 33° below 0(1). The cold 

 at (^ebec exceeded it, for the thermometer fell 

 to 42° (2). That at Torneao, obferved by 

 Maupertuis, was ftill greater, as it fell to 51*^ (3), 

 But this which appears extreme, compared with 

 what we witnefs, cannot bear comparifon with 

 that fometimes felt in many parts of Siberia, as 

 Tomfk, Kirenga, Jenifeik, where the thermome- 

 ter has been feen at 90^, 128°, and even 178^ 

 below o (4). 



Such dreadful cold, we cannot deny, was per- 

 nicious, nay fatal. In Peteriburgh, at- — 29°, the 

 face could not be kept uncovered above half a 

 minute (5) : and at Torneao, where the ther- 

 mometer fell — 51°, thofe expofed to the air 

 felt the breaft as if lacerated. Nor is it uncom- 

 mon for the inhabitants of thefe cold climates to 

 lofe fome member, as a leg or an arm, during 

 winter (6). Similar and more terrible are the 

 eifeds in Siberia : yet, in other parts of the earth, 

 cold is perhaps more intenfe. Such may Captain 

 Middleton have experienced in Hudfon's Bay, 

 as he has communicated to the London Royal 

 E 2 Society,
