DISEASES OF THE LUNGS. 791 



Nor would it be very difficult for intelligent indi- 

 viduals in good circumstances, to regulate the tem- 

 perature of their own private residences during 

 the colder months, so as to obtain all the advan- 

 tages of an artificial warm climate, if we except 

 exercise in the open air. But as the same ad- 

 vantages might be secured in a far more effectual 

 and economical manner, by the establishment of 

 a large Sanatorium for the reception of patients 

 labouring under chronic affections of the lungs, 

 it is greatly to be desired that such an institution 

 should be founded in some healthy place near 

 London, with intelligent superintendents to regu- 

 late the temperature of the rooms, the diet, cloth- 

 ing, exercise, amusements, &c. of the inmates, 

 who would in many respects be better off than in 

 a foreign clime. 



The manner in which diseases are produced 

 by the influence of external cold, or by any- 

 thing which reduces the temperature of the body 

 below the natural standard, has never been sa- 

 tisfactorily explained.. Nor is this very surpris- 

 ing when we reflect, that Physiologists have 

 never yet ascertained the specific office of animal 

 heat in circulation, sanguification, secretion, nu-

 our pathology and methods of treatment are still 

 imperfect, it is because the fundamental pro- 

 blems of physiology remain unresolved. Why 

 then is it that catarrh, influenza, croup, hooping
