ADDITIONAL NOTES AND CORRECTIONS.
Page 24. In the second line of foot-note, change two-thirds to four-ninths.
27. The exact date of the complete invention of copper-plate printing is unfixed. Vasari says that Finiguerra's discovery was made in 1450, but that the Italian practice of making plate prints began about 1460. It is obvious that the alleged discovery in 1450 of the feet that the blacking placed in incised lines could be transferred to paper by pressure was not the complete invention of copper-plate printing. Much more had to be done. The earliest dated Italian print by this method is of the year 1465. The earliest authentic German print is dated 1446. There are others attributed to the years 1422, 1430, 1440, but they are not accepted as genuine by Passavant. See Peintre-Graveur, vol. i, pp. 192-197.
Senefelder's first suggestion of lithography was entertained in 1796, but his vague notions about printing from stone did not assume a practical shape before 1798. He did not receive, and perhaps was not entitled to, his patent before 1800.
34. The exact size of the Assyrian cylinder illustrated on this page is seven inches high and three inches wide at each end.
64. On page 447, the date of the erection of this stone by Wittig is put down at 1508, which is the date given by Bernard and by many others. But Wetter, from whose book this statement was taken, knowing that Wittig was dead in 1507, altered the date to 1507. Helbig does not accept either date. He thinks that it should be 1504.

65. In foot-note, change exculptis to exsculptis.
77. I have followed De la Borde's translation of this indulgence, which makes the time seventeen thousand years, but Holtrop's translation is fourteen thousand years. The popes supposed to be associated with Gregory in the promulgation of this indulgence were the Anti-pope Benedict xiii at Avignon, and Pope John xxiii. Holtrop does not regard this as a print of 1418; he places it between 1455 and 1470.
82. It is possible that engraving on wood was done in England in the first half of the fifteenth century. Ottley, in his Inquiry concerning the Invention of Printing, page 198, describes an English print of the crucifixion, with legend in English, which he says may be as old as the St. Christopher. This is the legend: "Seynt Gregor. with oyer [other] popes & bysshoppes yn seer, Haue graunted of pardon xxvi. mill yeer. To yeym yat befor yis fygur on yeir knees Devoutly say .v. pater noster .&.v. Auees." Weigel has given other fac-similes of early English engraving.
95. Chatto says that Gringonneur was paid 56 sols about 1393. Passavant says 50 sols. Lacroix says 1392, and estimates the value of 56 sols in modern money at 180 francs.
98. In third line of second paragraph, change fifteenth to fourteenth.
104. In third line of foot-note, change printers to painters.
111, In foot-note, last line of small type, change chap. i to chap. ii.
130. Change John i, 3, to John iii, 1.
150. Lacroix gives the date of 1292 for the employment of the seventeen book-binders at the University of Paris.
177. In sixth line of note, change 1435 to 1430, and the word double to thrice.
180. In eleventh line, change 1385 to 1381.
218. The date of the termination of the Great Schism is usually put at 1447, but it was not fully ended until Pope Felix v abdicated the papal chair in 1449, and ordered the church to submit to Nicholas v.
250. Passavant (vol. i, p. 50) says that there is in the library at Heidelberg a copy of a xylographic edition of the Lord's Prayer, a block-book of ten leaves, which may be attributed to the fifteenth century.
299. In last line but two of note, change 380 to 280.
319. Holtrop says that Bellaert's name is first mentioned in 1485, as it appears in the fac-simile.
378. A document has been recently discovered at Strasburg which proves that Frielo Gensfleisch, the elder brother of John Gutenberg, was in Strasburg in 1429. This document is the signature of Frielo to a receipt for 26 florins due him on an annuity. See Book Worm for January, 1868.
397. It is not probable that this tool of four pieces was the press. Ottley, who thinks that Gutenberg's secret was not that of printing (Inquiry concerning Invention, p. 41), says,
