" To be bathed in the light and heat of a new sun, and washed 

 with the winds of a fresh sky, to feel the steam of an unwonted sur- 

 face of earth and the tension of a different magnestism and electri- 

 city to that to which we are accustomed, are important elements in 

 the recovery of health, particularly where moral circumstances also 

 are favorable. The hygienic map of countries gathered, as it might 

 be, from the physical character of the inhabitants, or from suscepti- 

 ble temperaments on the spot, would be a guide worth having in the 

 directions of patients to localities of specific benefit. In this respect, 

 we require something more precise than the guide-books which have 

 been written by the climatic physicians." 



WILKINSON. 



"Marvelous are the offices, and wonderful is the constitution of 

 the atmosphere. Indeed, I know of no subject more fit for profitable 

 thought on the part of the truth-loving, knowledge-seeking student, 

 be he seaman or landsman, than that afforded by the atmosphere and 

 its offices. Of all parts of the physical machinery, of all the con- 

 trivances in the mechanism of the universe, the atmosphere, with its 

 offices and its adaptations, appears to me to be the most wonderful, 

 sublime, and beautiful."
