rather than another, they consider the popular opinion to be 

 unsupported by any extended series of correct observation. 

 In the Annuaire for 1833, Arago, the learned editor, has pre- 

 sented the result of the observations of Schubler, in Germany, du- 

 ring twenty-eight years, or 348 synodic revolutions of the moon. 

 Durincr this period of 348 new moons, &c. the number of rainy 

 days were as follows : — 



It rained on the day of the new moon, . . 148 times. 



Do. do. first quarter, . . 156 ... 



Do. do. full moon, . . 162 ... 



Do. do. last quarter, . . 130 ... 



The observations of Schubler were made during eight years 

 at Munich, four years at Stuttgard, and sixteen years at Augs- 

 buro-. Asa good meteorological register has been long kept at 

 Geneva, the author thought it would be interesting to ascertain 

 from the tables, (which have been carefully published in the 

 Bibliotheque of that city), whether, during a period of thirty-four 

 years, viz. from 1800 to 1833, any inferences could be drawn for 

 or against the popular opinion on the subject of lunar influence. 

 He finds, during these thirty-four years, the number of rainy 

 days, and the quantity of water fallen, to be as follows : — 



Rainy days. Water fallen. 

 At the new moon, .... 123 432 lines. 



First quarter, 122 429.6 ... 



FuUmoon, 132 415.7 ... 



Last quarter, 128 368.6 ... 



Throughout the whole period, . 3,657 968 in. 93 lines. 



Thus it appears, that during thirty-four years, or 12,419 days, 

 comprehending 420 synodic revolutions of the moon, there have 

 been 3657 rainy days. This gives for every 100 days 29-45 

 rainy days ; and we find, that 



For every 100 days of new moon, 29.29 have been rainy. 

 Do. do. first quarter, 29.05 do. do. 



Do. do. full moon, 31.43 do. do. 



Do. do. last quarter, 30.48 do. do. 



Hence, it is evident that, during these thirty-four years at Geneva, 

 the days of new moon and the days of the first quarter have 

 been just about as liable to be rainy days as any other common 

 day of the month, while the days of full moon and those of the 

 last cjuarter, have been rather more liable. But although the 

 days of full moon have been rather more frequently wet days
