the Amazon and the Bio Negro, is stated between 78° and 81°, 
the extremes being 73° and 100°. The annual mean and the greatest 
heat is thus the same as what we have in British Burma and on 
the western coast (Malabar, Canara, and the Concan), but there 
is that difference, that in the northern part of these districts the 
thermometer falls lower during the cool season than appears to be 
the case in the equatorial forests of Brazil. By way of illustration 
I will give a table of means, and another of absolute extremes, of 
some stations on both coasts, to which, for the sake of comparison, 
I hare added Calcutta and one station in Assam. The figures are 
taken from Schlagintweit’s Meteorology of India, first part, 1866.
