In addition to the unbounded occupation of time and thought, necessary for the most effective employment of mind in the path of original discovery, there are far other requisites. In some sciences, many laborious transcriptions, in others still more laborious arithmetical computations, are required; in others, abstruse and complicated although known and regulated algebraical processes, must be gone through; in others, drawings of the most complicated description must be executed with almost overwhelming labour; in others, extensive experiments must be made. Again, in some, where mechanical means must be contrived for new and intellectual processes, it may be necessary even to invent and make new tools for the purpose of bringing mechanical art itself up to that degree of perfection which science demands. Although the contriving and directing mind engaged in researches that require such aids, ought undoubtedly to be united with a physical structure capable itself of accomplishing each and all that such pursuits require, yet it is often impossible that one human frame, however hardy, can sustain that labour: time itself would be wanting, limited as it ever must be by the duration of one human life. Yet if the powers of that mind and that frame have been rightly cultivated, and if the want of pecuniary means do not prevent their exercise, it is quite possible, by proper aid, to concentrate in one life the accumulated labour of many. Assistants of various degrees of manual and mental skill may be employed, the economical organization of their labour may be arranged. The most perfect effect of such an establishment can only be attained when the presiding head is never employed except on work for which money could procure no substitute, and when each assistant is devoted to work of the highest kind which he can successfully execute. He who directs a scientific establishment for the Government, has all these means provided for him, and is himself paid, though not always liberally, for his own labours. _He_ is to be deemed _qualified_ for the order of the Bath. _He_ who sacrifices profession and that position to which its most successful members usually attain, who spends a fortune in purchasing that assistance which alone can render his power effective, and has spent his life in cultivating highly that power for the advancement of science, is deemed by his country, however great his success, _disqualified_ for the Order of the Bath. But it is not the sound and wholesome part of the country—it is not the people of England who have arrived at this conclusion;—it is the insolence of power,—it is the meanness of party,—it is the selfishness of a clique.
