[Footnote 199: _Al._ 1443. See Azurara, _Guinea_, chs. lxviii-lxix.] In 1446, however, he followed up the reconnaissance of 1445 by another attempt at complete conquest, which also seems to have ended in failure, though the account that remains is very inadequate; perhaps in the future it may be supplemented from the disinterred treasures of Spanish documentary collections. We only know that Henry obtained, in 1446, from the Regent D. Pedro a charter, giving him the exclusive right to sanction or forbid all Portuguese voyages to the Canaries; that in 1447 he conferred the captaincy of Lançarote on Antam Gonçalvez,[200] and that Gonçalvez sailed to establish himself there. So far, according to Azurara; Barros and the Spanish historians would ante-date all these measures of 1446-7 by several years. In 1455 Cadamosto, sailing in the Portuguese service, visited and described the islands, and in 1466 Henry's heir, D. Fernando, made one more attempt to reclaim the Canaries for Portugal. It failed, and in 1479 the islands were finally adjudged to Spain, or the now united monarchy of Castille and Aragon.

Azurara, _Guinea_, ch. xcv.] * * * * * Fourthly, in the Madeira group, colonisation made progress during the Infant's lifetime. After the discoveries of 1418-20,[201] Madeira itself was divided up under the feudal lordship of John Gonçalvez Zarco and Tristam Vaz Teixeira; the former receiving the captaincy of the northern half with Machico for his chief settlement; the latter obtaining the southern portion, with Funchal as capital, and the Desertas as an annexe. From the language of the Infant's Charter[202] of September 18th, 1460, this settlement appears to have taken place in 1425, when the Prince was 35 years old. [Footnote 201: Cadamosto's statement that Porto Santo had been found 27 years before his first voyage, has caused some to date this journey 1445, instead of 1455, reckoning from Zarco's discovery of 1418, and has led others to post-date Zarco's discovery by ten years; but the number XXV is no doubt a slip for XXXV. This is a very common form of error at this period. Thus, in the "Cabot" Map of 1544, the year of the original Cabotian discovery of North America is given as MCCCCXCIIII, instead of MCCCCXCVII, by a (probable) malformation of the V, or simple inattention of the draughtsman. Also, in Grynaeus we have MCCCCCIV for MCCCCLIV.] [Footnote 202: Endowing the Order of Christ with the Spiritualities of these islands.]
