descending to a lower level than they had occupied during the day. 

 The mean temperature of the rainy months is 66° or the same as 

 that of August, which differs only from the warmest month 

 June 67.5, 1° from July 67, 2J from September the coldest month 

 63.25. The range of the thermometer during the whole of the 

 rainy months is only about 10° or 12°. The difference between the 

 dry and moist bulb thermometer during this season, is seldom so 

 much as 5° in the mornings, but generally from 1° to 3° in the morn- 

 ings and evenings, and 2° to 6° sometimes 8° in the day time. 



During this season many plants allied to tropical families make 

 their appearance, and the branches of the Oaks and Rhododen- 

 drons become covered with mosses and ferns, and in the thick coating 

 of the former, plants of many different families are produced, as 

 Orchidese, Scitamineae, a species of Thalictrum, and of Convallaria. 

 The ground is at the same time covered with plants of Euro- 

 pean families, as well with those belonging to such tropical families 

 as have been mentioned, as well as to Didymocarpeai, Melasto- 

 macese, and plants requiring moist situations as Drosera, Begonia ; 

 a sure indication of the moderation as well as moisture of the climate, 

 which can maintain at the same time plants requiring such opposite 

 climates. 



At the conclusion of the rainy season, or in what may be called 

 the autumn, the climate is most delightful, the air is extremely 

 mild, still and clear. The effects of the last may be observed in 

 the more rapid decreasing temperature, which had during the cloudy 

 season remained so uniform, and the dryness may be observed in 

 the difference between the dry and moist bulbed thermometer, 

 amounting in the mornings sometimes to 7°, in the day time from 

 8° to 15°, and in the evenings to 4° or 6°. 



The Meteorological phenomena observed in the years 1827 and 

 1828, have been reduced to a tabular form, which will give a good 

 general idea of the nature of the climate, as they nearly correspond
