BATH, ST. JAMES’S SQUARE, _April 30, 1799_. MADAM, It is with much satisfaction that I received through the hands of Dr. Herschel, the valuable publication you are so kind as to send me, and which indeed is the more welcome as I have the volumes of the “Historia Cœlestis,” and shall most probably have occasion to use them. Were Flamsteed alive, how cordially would he thank you for thus rendering the labours of his life so much more useful and acceptable to posterity, for he surely little thought that his great work required to be elucidated by an additional folio volume of explanations, errata, and indexes, the advantages of which, by their excellence and accuracy, must every day be more and more acknowledged, and future astronomers, as well as those of the present times will doubtless often be conscious of the merit and obligation you are entitled to. With many thanks, I remain, Dear madam, Your most obedient EDWD. PIGOTT. Dr. and Mrs. Herschel, whom I have occasionally the pleasure of seeing, though by no means so often as I could wish, are well, and desired to be mentioned to you.
