346 On the influence of the Moon on [Jult, 



Here the days of maxima are somewhat different from what they were 

 before, being the 3rd, 5th, 6th, and 7th days before new moon, the day 

 of new moon, and the first day after. 



Upon examining further, I found that this excess of rain towards the 

 new moon obtained in a degree through the succeeding months, May 

 and June, but that the ratio was somewhat altered. For instance (see 

 Table No. 2, of Calcutta year's rain), the rain that fell in the same days, 

 about the new moon, during a period of eight years, amounted to 83.73 

 inches, and for the rest of the lunar period to 52.04 inches, being in the 

 ratio of 16 : 10. The numbers of rainy days for the above two periods 

 respectively were 68 and 54, in the proportion nearly of 1*3 : 1. If we 

 particularize the quantities of rain, we find that the 3rd, 6th, 7th, and 

 8th days before the new moon are now become maxima, as well as the 

 3rd, 4th, 5th, and 6th, and 10th after it. In the third division of the 

 year, which I have confined to the month of July, the numbers approach 

 still more a ratio of equality, the respective quantities of rain being 

 43*60 inches and 28*78 inches, or in the ratio of about 1*5 : 1, and the 

 numbers of the rainy days are very nearly equal, being 6 1 and 60, or in 

 the ratio of 1.017 : 1. In the fourth division of the year, which I have 

 made to comprehend the months August, September, and October, the 

 ratio is altered, the quantities of rain for the two periods being 96*75 

 and 119*39 inches, or in the ratio nearly of 1 : 1*2, and the numbers of 

 rainy days 159 and 173, being as 1 : 1*1 nearly. The different numbers 

 are here placed, for the sake of comparison in a tabular form.

Upon looking over the days of maxima in this last case, we find them 

 to be the 3rd, 9th, and 11th, before the new moon, and the 3rd, 5th, 

 6th, 10th, 11th, and 12th, after. I must here observe, that the prdsent 

 mode of comparison is not strictly correct. As the lunar period is, pro- 

 perly speaking, only 29| days, the fifteenth day on the left hand of the 

 table only occurs alternately. The comparison, however, is sufficient for 

 my purpose. Taking the four periods of the year together, the inequalities 

 may be accounted for by supposing four days to be the principal maxima : 

 one of these being the fifth day after the new moon, and another the 

 9th day before it. It is true that the 9th day itself is but once a maxi-
