"The day before yesterday I received your letter dated so far back as August 25th. It appears to have been put into the London post, addressed to my clerk's lodgings, only last week, and reached me in the country November the 7th. I am thus particular as to dates, as I could not bear the imputation of having so long neglected the due acknowledgment of a letter from one whom I so highly esteem and respect. In regard to the question you state, I understood from the late Mr. Edwards, that he assisted in the general arrangement of the materials you supplied, as Dr. Hawkesworth did, in the case of a voyage by the great navigator Captain Cooke; and that the previous Account or Summary of your Travels delivered into the African Association was written by him; to which your fuller Account of your Travels in detail was subsequent. The word "author," I believe, does not occur in the passage you refer to; and if the words "compilation and recital" seem to bear any application beyond the prospectus before adverted to, or in any way to trench on your just pretensions as a writer, I truly lament the inaccuracy, and will take the most immediate means of rectifying the error, which circumstances may place within my reach; either by present correction or on a new edition of the work. My situation as Secretary of the African Association furnishes me with documents from which I have learned so highly to appreciate your character and to entertain so grateful a sense of your public services, that it would be painful in me, in the smallest degree to have stated any thing that might be so construed as to affect your just literary pretensions; although it is difficult to add to the just and high reputation you held independently, from the fortitude, discretion, and resource so eminently shewn in your distinguished and successful enterprise."

Mr. Park to Sir William Young.

Fowlshiels, 14th May, 1804.

"I perceive by your letter, that you meant the words 'compilation' and 'recital,' to refer entirely to the Abridgment of my Travels, which was written for the perusal of the gentlemen of the African Association, by Mr. Edwards, their Secretary.

"A printed copy of this Abridgment was delivered to each of the gentlemen at their annual meeting, but I believe it was never publicly sold. The greater number of readers are therefore but slightly acquainted with it; and to such, the words above-mentioned will naturally convey a very different meaning. Having thus explained myself to you, I hope you will see the propriety of correcting the passage above-mentioned as soon as possible. I must therefore request you will permit me to insert your letter in any of the periodical publications, or favour me with a correction of the passage, as you may think proper."

Extract from a letter of Sir William Young to Mr. Park

May 25, 1804.

"The letter which I wrote on the subject of the publication of your travels in Africa, is perfectly at your service to make any use of, which you may think proper. No measure can be more satisfactory and agreeable to myself, than that which may most fully render justice to your high and well earned reputation in every point of view."

APPENDIX. No. IV.

The question regarding the termination of the Niger is one of the most doubtful and obscure in modern geography, and in the present defective state of our information with regard to the interior of Africa, seems hardly to admit of a clear and satisfactory solution. Of the difficulties with which the subject is attended, some judgment may be formed from the various and even opposite opinions which have been maintained relative to the course of the Niger, since Park's discoveries have ascertained that it flows from west to east. As the enquiry is somewhat curious, a summary view of these different opinions, and of the principal arguments by which they are supported, may not be uninteresting to the readers of Park's life. To investigate the question with the accuracy and minuteness which it deserves, would not only very far exceed the limits of a note, but would require much more information upon this subject than the editor possesses, united with some previous habits of geographical disquisition.
