    HIGH ALTITUDE THEORY. y were assigned to Dr. Lombard, and he has arranged their statistics in three classes, according to the alti- tude of the locality :— 1. Statistics of localities of low altitude {basses regions), situated between 1,250 and 1,650 feet above the sea-level. 2. Statistics of localities of moderate altitude {regions moyennes), at an elevation of between 1,725 and 2,700 feet. 3. Those of high-level localities {Jiautes regions), situated from 2,700 to 4,000 feet above the sea- level. The ' low altitude ' class gave a phthisis mortality of 10-2 per cent.; the moderate altitudes, one of 9*4 per cent.; and the high level, one of only 5*1 per cent.; and certainly these bear out Dr. Lombard's conclusion that, while localities of low and moderate altitudes—that is, between 1,250 and 3,000 feet— present a large phthisis mortality, above this 'phthisis zone,' as he terms it, the disease diminishes, becoming extremely rare; and above 5,000 feet it disappears altogether. Similar evidence is given by Drs. Berry and Briigger, from the Upper Engadin, lying 5,000 and 6,000 feet above the sea; and by Dr. Spengler at Davos-Platz, situated at a slightly lower elevation.
