Observations at Port Louis. 99 



The remark which accompanied my Observations in 

 the preceding- Year, (laid before the Society on the 3rd 

 December 1846,) occurs again. Unusual depressions 

 of the Barometer take place very frequently at or 

 about the Phases of the Moon. 



Besides many less remarkable instances, on the 18(h 

 of December 1846, the lowest indication in that month 

 took place exactly at the change of the moon ; on the 

 16th of April, the day after the change, and on the 

 29th of May 1847, the day preceding full moon, simi- 

 lar depressions occur. The 31st of January 1847, the 

 day of full moon, and the 7th of February, the day on 

 which the moon entered the first quarter, show the low- 

 est indications in the year. There was a continued 

 gale, with heavy rain and very threatening weather, 

 from the 15th of January till the 19th of February. 



I have the honor to be, 

 Sir. 

 Your most obedient servant,
