issued, when tins basaltic mass was raised. We lost sight 
of the small islands of Alegranza, Montana Clara, and Gra- 
ciosa, which appear never to have been inhabited by the 
Guanelies. They are now visited only for the purpose of 
gathering archil, which production is, however, less sought 
after, since so many other lichens of the north _ ot Europe 
have been found to yield materials proper for dyeing. Mon- 
tana Clara is noted for its beautiful canary-birds The note 
of those birds varies with their Hocks, like that of our chat- 
finches, which often differs in two neighbouring districts. 
Montana Clara yields pasture for goats, a fact which proves 
that the interior of this islet Is less arid than its coasts. 
The name of Alegranza is synonymous with the .lot ous, (La 
Joyeusc.) which denomination it received from the first con- 
querors of the Canary Islands, the two Norman barons, Jean 
de Bethencourt and Gadifcr de Salle. I his was the first 
point on which they landed. After remaining several days 
at Graciosa, a small part of which wo examined, they con- 
ceived the project of taking possession oi the neighbouring 
island of Lanccrota, where they were welcomed by Guadarfia, 
sovereign of tbc Guanelies, with the same hospitality that 
Cortez found in the palace of Montezuma. The shepherd 
king, who had no other riches than his goats, became the 
victim of base treachery, like the sultan ot Mexico. 
Wo sailed along the coasts of Lanccrota, ot flic island ol 
Lobos, and of Fortcvcntnra. The second of these islands 
seems to have anciently formed part of the two others. 
This geological hypothesis was started in the seventeenth 
cent my by the Franciscan, Juan Galindo. That writer 
supposed that king Juba had named six Canary Islands 
only, because, in his time, three among them were contigu- 
ous. Without admitting the probability of this hypothesis, 
some learned geographers have imagined they recognized, in 
the two islands Nivaria and Ombrios, the Canaria and 
Capraria of the ancients. 
The haziness of the horizon prevented us, during the 
whole of our passage from Lancerota to Teneriffe, from dis- 
covering the summit of the peak of Teyde. If the height 
of this volcano is 1005 toises, as the last trigonometrical 
measure of Borda indicates, its summit ougat to be visible 
at a distance of 43 leagues, supposing the eye on a level
