occurred in Lima in 1791, was 78°. 4, and exceeded that of 

 the hottest month of the same year in London, August, by 

 9».4. The March of the following year was still hotter in 

 Lima, the mean degree of temperature having been 80°. 25. 

 The cause of the difference of more than 9" of mean tempera- 

 ture between the two capitals, at the same time that the mercury 

 was never higher at Lima than it has been in London, ap- 

 pears to have been owing to the constancy of the heats in the 

 former city, and to the few variations to which the atmosphere 

 is there subjedled. Between the 1 7th and 30th of September 

 1 79 1, both days included, there was not the slightest varia- 

 tion in the observations made at noon. In London, on the 

 other hand, the flu6luations, which are at all times unceasing, 

 ^produced in the month of June 1791, according to the obser- 

 vations of the afternoon, varieties of temperature to the extent 

 of 28°. But for the presence of the southerly winds which 

 prevail on the coast, the changes of temperature at Lima would 

 be still less, as in other parts of Peru. In the plains of Bom- 

 bon, there is a variation of 6° only, throughout the year; and 

 at Santa Fe, the observations of two successive years afforded 

 a result of only 3° of variation. 



^ To complete the series of subje£ts introduced into this work, 

 an Indian woman of a village near Lima, holding in her arms 

 an infant, is represented in Plate XX. in her simple and rustic 

 garb. The portraiture of this female peasant maybe regarded 

 as a companion to the male Indian wearing the poncho, de- 

 lineated in Plate XVII.
