[17] Previous to the expedition quitting England, I had provided myself with medals, to give away to the Indians with whom we might communicate, bearing on one side the figure of Britannia, and on the reverse George IV. "Adventure and Beagle," and "1826."

[20] From an attentive perusal of the voyage of Magalhaens, I have lately been led to think that this is the mountain which Magalhaens called Roldan's Bell. Sarmiento has, however, assigned that name to a mountain at the back of his Bay of Campana, which will be noticed in it's proper place. The name of Mount Sarmiento was too long, and too well established with us, or I should have restored the name bestowed upon it by Magalhaens. Herrera, in his Descripcion de las Indias Occidentales, cap. xxiii, notices the "Campana de Roldan" as a great mountain in the midst of the entrance of a channel; they gave it this name (Campana de Roldan) because one of Magalhaens's companions, named Roldan, an artillery officer, went to examine it. "Y la Campana de Roldan una Peña grande en medio al principio de un canal: dieron le este nombre porque la fué a reconocer uno de los compañeros de Magallanes llamado Roldan que era artillero."

but as the last observation, from the angle of elevation being greater, was more likely to be correct, 6,800 feet is considered to be its elevation.
[22] At a subsequent visit, embracing a period of 190 days, it was only seen on twenty-five, and during seven days only was it constantly visible. On the remaining eighteen, portions only were seen, and those but for a few hours at a time.
