and at 3 p. m. It may also be remarked that the writer has shown that 

 meteorites are most numerous in mountain regions,* so that the high 

 points seem in every respect to be the most successful in acquiring 

 meteorites. 



It would be possible from the writer's data to compare falls at 

 different intervals and for different periods in order to determine 

 whether various periods agree in times of fall. Such examination of 

 the records as the writer has made shows that the distribution of the 

 falls is about the same in all the periods. In order to secure inde- 

 pendent testimony on this point the writer's results may be compared 

 with those of Haidinger, who in 1867 f gave the hours of 178 meteorite 

 falls. His table was as follows: 



12 1 2 3 4 5 6 7 8 9 10 11 



am 1 3 2 2 4 5 4 13 5 7 5 2 3 = 74 



P. M 9 11 11 19 18 9 6 10 5 1 o 5 = 104 



On examination of these falls by name, however, it appears that 

 some are assigned times of fall which later investigation has shown 

 to be unreliable, as is true of the meteorite of Mincy for example and 

 others listed are not now recognized as meteoritic. For these reasons 

 about 40 falls must be eliminated from Haidinger's list. Omitting 

 these the result is as follows: 



12 1 23456789 10 11 



am 1 1 1 2 3 3 4 10 5 5 5 17 = 57 



p m 7 9 9 16 15 7 5 7 3 o o 3 = 81 



An excess of afternoon over forenoon falls is seen here as in the 

 writer's list, although the proportion is less, it being nearly 2 : 1 in 

 the writer's list and 1.4 : 1 in Haidinger's list. More significant 

 perhaps is the fact that both lists show an excess of falls at 7 a. m., 

 11 a. m., and 3 p. m. 



On the whole the study of the times of fall of meteorites in the 

 manner here adopted seems to show (1) that they differ considerably 

 from meteors in times of fall, (2) that they are not noticeably related 

 to any of the well known star showers and (3) that the rate of their 

 supply to the earth is remarkably uniform.
