gine, from a perusal of the thermometrical tables, that the co- 
lony of the Cape must be ill adapted for the abode of the con- 
sumptive. Experience, to which we can never too often recur, 
demonstrates the accuracy of this deduction. Pulmonary con- 
sumption is not an unfrequent disease with the colonists, and 
annually cuts off great numbers of the class of natives called 
Hottentots.

From the above table, and a few others which exist, may be 
seen the remarkable equability of temperature enjoyed, as well 
by the great ocean, as by the superincumbent atmosphere. 
This, which is neither disturbed by storms, nor changes of sea- 
sons, nor by the vicissitudes of day and night, has not been suffi- 
ciently insisted on by meteorological, and but ill understood by 
medical writers. Hence we find them attributing to various
