128 -i)n the Climate of the Canary Islands, 



difference to exist, which has been already stated to have been 

 observed at Santa Cruz between the temperature of noon, and 

 that of the mean between noon and sunrise. 



By this table it is seen that the maximum of heat takes 

 place at Las Palmas in October instead of August^ that as far 

 as September the progression is regular, and accords with the 

 register of Santa Cruz ; but that, instead of diminishing in 

 September and October, as is usual from the decreasing 

 southern declination of the sun, the heat, on the con- 

 trary, continues to augment, until in the middle of October it 

 attains a height only known in the hottest tropical climates. 

 The general understanding of the inhabitants corresponds with 

 the register ; and the peculiarity of the climate is marked, as 

 might be expected, by a corresponding peculiarity in the vege- 

 tation. Thus the Palm-trees, from which Las Palmas takes its 

 name, and which flourish greatly in its vicinity, yield ripe dates 

 in abundance ; whereas the few trees of the same kind which 

 are found in Teneriffe do not ripen fruit. The Euphorbia 

 Balsamifera, which requires a great deal of warmth, is found in 

 the neighbourhood of Las Palmas, as high as eight hundred 

 feet, forming bushes ten or twelve feet high ; whereas at Santa 

 Cruz, and at Oratava, it hardly rises above the ground. Nearly 

 the same may be said of the Plocama Pendula. The gardens of 

 Canary are adorned with East and West India trees, not seen in 

 Teneriffe ; Poinciana Pulcherrima, of uncommon size and 

 beauty ; Bixa Orellana and Tamarind trees, as large as the 

 Lime-trees of Europe. A magnificent avenue of the large trees 

 of the Carica Papaya, or Papaw tree, is found in the hospital of
