' In a paper on the Meteorology of Bourbon, by Mailland, published in the Annuaire de la SociSte Meteoro- 

 logique of France, for January, '^l'862, he intimates that the observations at St. Paul should be rejected on 

 account of its local position on the leeward side of the island; and remai-ks, in regard to Port Louis, that its 

 position on the island of Mauritius is precisely similar to that of St. Paul on the Isle of Bourbon, and that, 

 therefore, it would be an error to judge of the meteorology of the whole island from observations made at 

 Port Louis. Bourbon is a volcanic island, of elliptical form, 38 miles long and 28 wide, and is traversed from 

 north to south by a chain of mountains that rise at some points to the height of near 10,000 feet. The intenor 

 of Mauritius is mountainous, but the mountains are not so high. 



2 For the first six years only. Mr. Meldrum's observations for the last nve years are as follows, viz. : — 

 North 69 East 1280 South 39 West 111 Variable 98 



N. N.E. 47 E.S.E. 1803 S. S. W. 25 W. N. W. 176 Calm 1076 



N.E. 73 S.E. 1203 S. W. 32 N.W. 149 Total 7300 



E. N.E. 494 S. S.E. 454 W.S.W. 62 N.N.W. 109 



Hence the direction of the resultant for this latter series is about li. S. E., and its ratio to the sum of the winds 

 about .53, scarcely difl'eriug from the series computed above.
