I have addressed to you, by the Post Office, the first No. of the Biography. &c.—which I beg the favour of you to accept, with my grateful acknowledgements of your kind attention to my former letter. The hurry with which this vol. has been urged into the world, to meet the conveniences of printers & publishers, has left me no time for elaborate research, or for studying the graces of composition; & I doubt whether, even with competent abilities, it could have been rendered, in the midst of the many obstacles that have been opposed to the execution of it, worthy of your approbation.—The succeeding numbers, with the assistance I have been promised, will perhaps appear with fewer imperfections; & being yet in the spring of life, I may live long enough to render the whole work, by the corrections that future experience may enable me to make, more equal to the importance & dignity of the subject.
