My Dear Sir
Our thoughts about the Index jumped together, as they say, as you will perceive by the enclosed from Mr Dallas2—to whom I wrote 2 days ago— By this post I send you his Specimen—3 Will you address him direct at York to save loss of time? I hope he is working to your satisfaction.
Here is a matter wch may interest you—not a “Cock & a Bull” but an Ass & a Bull— I have a MS journey in Asia Minor—the writer of wch a respectable American Missionary4—met with the offspring of these two animals & has made a drawing of the specimen & states that it is of common occurrence in that country.
I must confess—I do not believe it & if you do not—I shall advise the author to suppress the phenomenon
I shd like to know what opinion you entertain, & whether you are acquainted with any such instance of extra-breeding
I am | My Dear Sir | Yours very faithfully | John Murray
