"He set too low a value on his own works, and always feared lest any thing might lower his reputation. His love of accuracy, likewise, acted as an impediment: those who take the most comprehensive views have the clearest knowledge of what may be deficient: he could see the improvements which were desirable, and while he had not yet attained them: he was unwilling to send out any thing to the public in a state which he considered to be imperfect. There was also another circumstance which operated against his publishing to any great extent: he certainly composed with difficulty; his writings are full of erasures; and after repeated transcriptions, his language was not always the happiest in its construction or arrangement. He was not remiss in noting what occurred to him, and making memoranda, where the words, which first occurred to him, were sufficient to register his thoughts, and recall them at any future time to his remembrance: but to dwell on the expressions which he should use, and to employ himself in polishing them for publication, seem to have been a task of irksome difficulty to him. No one writes well, who has not studied and practised it; and no one is inclined to acquire the habit, who does not enjoy some degree of facility in the execution of his purpose. It is not therefore astonishing that the voluminous historian of astronomy should have found that "Bradley n'avait presque rien publiée [Bradley had almost published nothing]." Besides the tables of Jupiter's satellites and a few others of no great extent, all that he could be found to have himself given to the world is comprised in seventy-two pages of the present volume. But when every thing is considered, we have no reason for regret; if he had written more for the press, he must have done less for our information;—the facts which he established, and the discoveries which he made, are of an intrinsic and inestimable value, beyond all comparison with any dissertations, in which he might have enlarged upon them."
