The number of accidents given in the Report as occurring between 8-9, 12-1, 

 1-2, and 5-6 is doubled to allow for the meal-times, which, as the Report of the Com- 

 mittee itseK states, take place from 8-8.30, 12.30-1.30, and 6.30-6. 



12-5.30 accidents are multiplied by 6/5 to allow for Saturdays, except in (2) 

 where Saturdays not included.

The figures are quoted from the Tables in the Annual Reports of the Chief In- 

 spector of Factories referring to Accidents occurring from Monday to Friday, and 

 reportable either to the Inspector only or to the certifying Surgeons and Inspectors. 

 These tables class accidents according (1) to time of day when they occurred ; (2) 

 the working hour ' round ' which they occurred {e.g., eighth hour would include 

 accidents occurring after 7^ hours work and before 8J hours work). 



These figures do not attempt to give the number of accidents per number em- 

 ployed at each hour. Hours where few are working owing to meal-times or short- 

 time are compared with full working hours when accidents will ipso facto be more 

 frequent. 



The following corrections must therefore be made : 



( 1 ) Omit all hours where factories may not be working full. Now, where England, 

 Scotland and Ireland are all combined, the start may be any time from 6 to 8, break- 

 fast from 8 to 10, dinner from 12 to 2, and the stop from 5 onwards. This leaves 

 only the hours from 10-11, 11-12, 2-3, 3-4, 4-5 as worth considering among the 

 time of day figures. Among the working-time figures, the occurrence of meal-times 

 is almost incalculable. The following plan, however, escapes uncertainties. 



If the working hours be divided into : A, the first half -hour and next hour, and B, the 

 second to the eighth, and C, the ninth hour, it is certain that C will consist (see Note) 

 of one fuU working hour, A of one and a half fuU working hours, and B of five and 

 a half working hours where the ' two-break ' sj'stem is worked, of six where there 

 is one break only (B = seven hours — one hour for dinner only or one hour and a
