My dear Sir

I hasten to thank you for your gift—precious not only to me but to Mankind—¹

Should any thing occur to me—that I think might be useful—I will write again after I have read the work which is a great relief in the midst of our details—as shown in the annexed yellow Book which you might like to glance over at your leisure.²

You will see what poor artifices—& instruments—we employ to catch you on April 3 next.³

I am my dear Sir | ever yours faithfully | W. Farr
