 In addition to about 10 written copies 

 (for 2nd edition of ' Times ' and some 

 other evening papers and one or two sub-

595 lithographed reports are printed daily. 

 Of these about — 



525 copies are issued daily. 

 6 do. do. weekly. 

 8 do. do. monthly. 

 16 do. do. half yearly. 

 Of those issued daily and weekly, about 

 300 are issued to subscribers, and 

 the remainder are sent free to Public 

 Offices or for exhibition at seaports, 

 or in return for observations from 

 volunteer observers. 



It should also be remarked that since the 1st of April, 1875, Daily 

 Weather Charts have appeared in the ' Times ' and other newspapers. 

 The form of these charts and the method of producing them in time for 

 publication were first initiated by a member of the Committee. 



Since January 1, 1876, arrangements have been made by which a chart 

 for 6 p.m. is supplied to the ' Times ' at the expense of that journal. 



As regards actual work effected in this Department, the Office may 

 point to the following papers : — • 



N. O.l. A Paper by Mr. Scott confirming the universal relation between 

 the direction and force of the wind and the differences in 

 barometrical readings, which had been already propounded
