dice of hot air on the Lungs, so far as the circumstance of its mere 

 heat is concerned in the question. For, in Canada and Russia, where 

 the cold in winter is so intense, the superior classes of inhabitants 

 heat their apartments by means of stoves, so highly, that the mer- 

 cury rises to 70 degrees, or even higher, and yet they have no hesi- 

 tation in encountering the prodigious difference of temperature sub- 

 sisting between the air of their apartments and the external atmos- 

 phere ; after they have first taken the precaution to confine the heat 

 of their bodies by means of furs, feathery skins, woollen cloths, and 

 such other materials as are slow conductors of heat. But, if in- 

 stead of putting on a great quantity of such sort of Cloathing, they 

 were to strip themselves of that which they wear in their houses, and 

 in that state expose themselves to the external air, the powers of life 

 would be found unequal to endure a change so enormous, in spite of 

 rapid exercise, and even death would, in some cases, consequent! v 

 ensue. All wonder, therefore, on account of the superior hardihood of 

 Horses that are kept without Cloathing, must cease when these cir- 

 cumstances are taken into consideration. For, the state of their 

 coats in winter (more especially if they have been kept in the open • 

 air, or in cool well-ventilated stables) will effectually prevent their 

 being subjected to such extreme vicissitudes of heat and cold as 

 Horses which are cloathed must be so frequently exposed to. In fact. 

 Horses with long and tough coats, will have little or no call upon the 

 powers of life to resist any change of tempemture at the outset of 

 their exercise. And even if they be rode so as to perspire pretty pro- 

 fusely, yet, their coats will absorb a great quantity of sweat, and tiie 

 conversion of that iluid into vapour, will, on this account, be tardilf 

 i^ffccted.
