"The contents of the following pages are the result of 145 days' close attention by a very industrious man. The knowledge of such a task having been undertaken and completed, caused some alarm among the booksellers, who had expended a considerable sum of money upon the reprint of Shakspeare, of which this MS. discloses the numerous errors. Fearful, therefore, lest this should be published, they made many overtures for the purchase of it, and at length Mr. Upcott was induced to part with it to John and Arthur Arch, Cornhill, from whom he expected a handsome remuneration; he received a single copy of the reprint, published at five guineas. "N.B. This copy, _corrected_ by myself from the above MS., I sold to James Perry, proprietor of the _Morning Chronicle_, for six guineas: which at his sale (Part III.) produced 12l. 1s. 6d. WM. UPCOTT." At the end of the volume is written: "Finished this collation Jan. 28, 1809, at three minutes past 12 o'clock. WM. UPCOTT." Upon comparing these remarks of Mr. Upcott with Lowndes' _Bibliographer's Manual_, p. 1645., col. 1., it will be seen that the latter was not accurately informed as to Perry's copy; Professor Porson having had no farther share in that laborious work than the recommending Mr. Upcott to undertake the collation, from which Perry's copy was subsequently corrected. F. C. B. * * * * * PHOTOGRAPHIC NOTES AND QUERIES. _Le Grey and the Collodion Process._--As the claim to the invention of the collodion process is disputed, I think, in justice to MR. LE GREY, whom all will acknowledge as a talented man, and who has done much for photography, that the claims he puts forth, and which I give, should be known to your readers who have not got his work, as they are in direct contradiction to MR. ARCHER'S letter in your 165th No. In his last published work, page 89., he states: "I was the first to apply collodion to photography. My first experiments were made in 1849. I used that substance then principally to give more equality and {48} fineness to the paper. I employed for that purpose a solution of iodide of potassium in alcohol of forty degrees saturated with collodion. "In continuing these studies I was induced to apply this body upon glass, to obtain more fineness, and I was soon in possession of an extremely rapid proceeding, _which I at last consigned to the pamphlet that I published in 1850, and which was translated into English at the same time_. "I had already at that time indicated the protosulphate of iron for developing the image, the ammonia and the fluorides as accelerating agents; and I was the first to announce having obtained by these means portraits in five seconds in the shade.
