RAILWAY ACCIDENTS. 

 The following is a like summary for 1850-1 : 



Analysis of Railway Accidwits for the Two Years enditig 

 December 31, 1851. 



12. To deduce from these reports any certain conclusions, 

 either as to the danger incurred by the railway traveller or the 

 efficiency of the railway management, it will be necessary to 

 ascertain in each case the total mileage of the passengers trans- 

 ported, and to compare with this mileage the accidents. 



By means of the returns of the passenger traffic, compared 

 with the average fares in proportion to distance, it appears that 

 the total mileage of the passengers of all classes in each of the 

 intervals to which the above returns refer, was as follows : 



Mileage of Passengers. 



In two years ending 31st Dec., 1848 . . 1830,184617 

 In two years ending 31st Dec., 1851 . . 2282,752756 



The meaning of these numbers is, that the total movement of 

 passengers on the railways was the same as if 1830,184617 had 

 been carried one mile in 1847-8, and 2282,752756 had been 

 carried one mile in 1850-1. 



By comparing the number of killed and wounded with these 

 numbers, it will be easy to determine the number of persons of 

 each class which were killed and wounded in the transport of a 

 given number of passengers over a given length of railway. 



13. Let it be required, for example, to determine the numbers 



distances travelled. Thus, if the risk in travelling 100 miles be 100,000 

 to 1, the risk in travelling 200 miles will be 100,000 to 2, or 50,000 to 1, 

 and the risk in travelling 50 miles will be 100,000 to i, or 200,000 to 1, 

 and so on.
