averages being respectively 30*^7 and 0°2 cent. (86°3 and 32°4 

 Fahr). 



These numbers alone suffice to £orm an idea respecting 

 the goodness and comfort o£ this climate. We use the word 

 "comfort" according to Dettweiler, Director of the sanatorium 

 of Falkenstein, respecting the cHmate of the residences of 

 the kind of which we are treating; this Physician tells us : 

 "Comf ortable climates and uncomfortablo climates can be dis- 

 "tiugnished: the first are those which need less; the others 

 " those which exact more care in the mode of clothing to 

 " avoid all noxious inflnence Among the residences more or 

 " less uncomfortablo from this point of view, can be noted 

 " all those of the centre of Europe, because of the brusque 

 " variations of temperature. But this does not inf er that those 

 " of the South have not also their dangers." 

 *l^ Dr. Licéaga, substitutos for this classifications, that of 

 " climates absolutely advantageous and climates relatively 

 usef ul." He places among the first, those of the Central table- 

 land of México, and among the second, the European clima- 

 tes, mentioned by Doctor Dettweiler. ( ' ) 



On the other hand, these Sanatoriums of Eui'ope are very far 

 from possessing the allitude which the Central Table-Land 

 of México has, at once with a climate so soft. Only in the 

 Himalayas and inthe Andes can onerise toahigher altitude 

 than that which the Mexican Central Table-Land posseses and 

 nevertheless enjoy such soft and healthful climates as ours 

 (in México) — But — at the same time these last regions have a 

 serious inconvenience for those of the great mass of humani- 

 ty which populates Europe andNorth-America. — These being 

 the most interested in this subject, as they; more than any 

 other are persecuted and undermined by tuberculosis. This
