sailors, or they are those who neglect tlie precautions 

 which are essentially necessary for the full development 

 of the advantages of a Nile voyage. The great difference 

 of temperature between night and day, even in the shade, 

 independent of the bright mid-day sun and the night fogs 

 render it desirable that invalids labouring under chest 

 disease should not expose themselves outside the boat 

 much after sunset nor before sunrise, and certainly never 

 without being protected by sufficient woollen clothing. 

 These latter precautions are not so much needed between

 are chilly cathedrals, cold picture galleries, and such like, 

 which fashion demands the stranger shall visit, be he an 

 invalid, or in health, and for which he must assume a 

 spurious enthusiasm, if fi'om defect of nature or education, 

 he lacks the taste. 



It is of real importance that the invalid shall leave his 

 room, not full of some excursion to a cathedral or ruin, 

 but simply to be in the open air, to wander about where 

 his fancy may load him, sure of finding himself gratified 

 and amused. He returns ere he feels fatigue, for he has
