The influential English geologist is actually best known for his "Origin, History and Principles of Gothic Architecture," a 1797 lecture delivered in Edinburgh that was subsequently published in a number of editions; he was father of the noted travel writer Basil Hall (1788-1844). Excellent content ALS, 2pp, 7¼" X 8 3/4", Edinburgh, Scotland, 1824 April 20. Addressed simply to "Sir." Very good. Slightest of age toning. Interesting bookish contents, reading in part: "I now return with many thanks the books which you have been so kind as to lend me. The following is the list of them which I trust you will find to be correct. The principia of Sir I. Newton translated into English by Motte in two volumes... Robinson's Mechanical Philosophy... Nouvelles experience sur la resistance des fluides... I have used the freedom to keep these books some days longer than I intended to have done; being tempted to run over the last which I have done with great satisfaction having used the freedom to cut open the leaves. The book contains many interesting suggestions towards the execution of the experiments... and I shall be glad to resume it again when I hope for the advantage once more of your advice & assistance.... at the same time I beg of you to accept of a copy of my book on Gothic Architecture...." Bold and attractive, in Hall's usual sprawling hand.
