The course that is actually pursued is to have a separate establishment at Woolwich, with an officer, and several non-commissioned officers on extra pay, so that the account stands thus:—[24] £ s. d. One officer, extra pay 182 10 0 One non-commissioned officer, ditto 27 7 6 Three non-commissioned officers, ditto 68 8 9 Contingent, not exceeding 200 0 0 ------------ Apparent expense £478 6 3 But to this must be added— The full pay of Lieut.-Colonel 300 0 5 His extra pay 273 15 0 Full pay of one officer, if a Captain 192 16 3 Ditto one non-commissioned ditto[25] 20 0 0 Ditto three ditto ditto 50 0 0 ------------- Real expense £1,314 17 11 In the estimate for civil service for 1850[26] the following items occur:— £ s. d. Extra pay to Colonel Sabine, Royal Artillery, for services in connexion with the Magnetic and Meteorological Observations, for ten years, from 7th May, 1839, to 7th May, 1849, at 15s. a-day 2,739 15 0 Deduct 3s. 4d. per day granted him from 1st June, 1841, to 7th May, 1848, as compensation for loss of command pay 434 8 0 -------------- £2,305 7 0 This certainly requires an explanation. Here is an officer not doing the services of his profession, who it seems has been allowed a compensation for what he _might_ have received if he _had_ rendered those services: notwithstanding which, at the end of ten years, he claims and is allowed the above sum of £2,305 7_s._ for services the payment of which it would seem by this account was never contemplated during those ten years. It is also to be remarked that Colonel Sabine does not reside at Woolwich, where the only effective portion of the work is carried on. § But to return to our argument: it is singular that even the principles on which science ought to be rewarded, are not entirely settled. Should all equally great discoveries be rewarded in the same way, without regard to the different positions in society which the discoverers occupy? If this principle were admitted, the rewards must be very large, or there would be none for the higher classes of society.
