_ It isnot my design, in thin controuniennialns to cdslekes dhepidiis. 
But the facts and results which I have delineated on the accom- 
panying maps,* indicate courses of circulation in the atmosphere 
which are nearly and mainly horizontal ; while the common the- 
ory alleges a course or circuit of circulation, in each hemisphere, 
which is essentially vertical, the warm air being supposed to as- 
cend near the equator to great elevations : and there flow outwards, 
to supply the inward current from the higher latitudes; the obli- 
quity from a north and south: direction being of course due to the 
earth’s rotation. I propose, therefore, to state ina summary way, 
some of the facts and considerations wetiin in. did own views 
serve to invalidate this calorific theory. 
'~ 1. The specific difference of mean Se eatistiel in the satan 
tropical winds as compared with: equal zones af vee ons 
winds, is te he dy namical 
effects which ‘are exhibited in these ‘winds. 1 am not aware that 
any successful eels “has: been apa to prove the:eonverse of 
this objection. ~ 
~ 2.° Phe rising. of the: saan bay of An trade wind in tbe 
equatorial latitudes, in the manner alleged, has never been con- 
ed by observation ; and, as I apprehend, may safely be deni- 
ed. ‘Nor has any proof of ale; sania bekh sia other than infer- 
jomena, whic! 
Ithink may be exp lained in a manner. 
3. The nent snow line of of the , Andes has been found-n near 
one thousand feet higher in 16° to’18° south latitude than at the 
equator, or om the parallel of the equatorial calms of the Atlantic. 
This fact, in a-region so fa worable to an equable development of 
natural influences, I aie! to be wholly conclusive against the
