TEMPERATURE OF APARTMENTS. 243 



When we think of all this, and remember 

 that people can live very comfortably in 

 climates like Labrador, and Greenland, and 

 Norway, and Lapland, and Siberia, where 

 everything around them air, water, earth, 

 trees, &c., is cooled down to less than half 

 the heat of the human body, for almost all the 

 year, and to the freezing point, (32 of the 

 thermometer,) a part of the time, is it not a 

 great wonder that all our bones, and flesh, and 

 blood, can keep up to a temperature of 98, or 

 nearly that, not only through an hour, or a 

 day, but through a pretty long life ? 



It is, indeed, almost a miracle ; or would be 

 thought so, if we thought anything about it. 

 It shows at least, how wonderful life is. For 

 not only man, but all living animals have this 

 same power. Birds have even a higher heat 

 than man. The blood of some of them rises 

 to a temperature of about 108. If it were 

 not so, they would often freeze to death in the 

 cold season, and perhaps split to pieces ; as the 

 frost, in swelling it, sometimes cracks the fro- 

 zen ground to pieces, and as trees are some- 

 times split in the same way, in very severe 

 winters.
