APPENDIX. 



Climate — Canton and Macao. 



The quantity of rain recorded by Kerr (a respectable 

 and intelligent gardener and botanist sent out by Sir 

 Joseph Banks) in his Meteorological Journal, which fell 

 on the 10th of May, 1810, at Macao, is 12*10 inches; but 

 this I consider an error. I have, consequently, corrected 

 it by forming an average out of the quantity which fell for 

 a few days before and after. The quantity, then, which 

 fell in inches for each month, from 1808 to 1811, say from 

 the middle of October to the middle of April at Canton, 

 and the remaining portion of the year at Macao (dividing 

 the year into monsoons), may be stated as follows : —

Temperature and its Monthly Variations. 



I am induced here to give an extract of Mr. Bletterman's 

 Journal of the highest and lowest range of the thermometer 

 for each month during eleven years, from 1806 to 1808, 

 and 1810 to 1817, as exhibiting a remarkable coincidence 

 with the daily mean temperature as given by Kerr, from 

 1807 to 1811; also the monthly variation of temperature 

 as exhibited in these Journals.
