?nd the $t'?. of Mac, V?haeni. ? �vithout being particularly warmly clad, and yet not feeling the least cold; and in the winter, the thermometer, on similar occa- sions, has been at 94 � Rfi �thout my suffering the slightest inconvenience. This I attributed at the time to the peculiar still- ness of the air, although, within a short distance in the offing and overhead, the wind was high. Whilst upon this subject, them are two facts which may be mentioned as illustrative of the mildness of the climate, notwith? standing the lowness of the temperature.. One.is the comparative warmth of the sea near its surface, between which and the air, I have, in the month of June, the middle of the winter season, observed a difference of 30 �on which occasion the sea was covered with a cloud of steam. The other is, that parrots and humming-birds, generally the inhabitants of warm regions, are very numerous in the southern and western parts of the Strait-- the former feeding upon the seeds of the Winters bark, and the latter have been seen by us chirping and sipping the sweets of the Fuehs/a and other flowers, after two or three days of constant rain, snow, and sleet, during which the thermometer has been at freezing point. We saw them also in the month of May upon the wing, during a snow shower; and they are found in all parts of the south- west and west coasts as far as Valparaiso. I have since been in- formed that this species is also an inhabitant of Peru; so that it has a range of more than 41 �latitude, the southern limit being 53-� south * Tierra dei Fuego is divided into three large islands by two channels; one of which is opposite to Cape Froward, and the other fronts Port Gallant. The easternmost, Magdalen Sound, trends in a due south direction for nineteen miles, and separates the clay slate from the more crystalline rocks which seem to pre- dominate in Clarence Island, and are chiefly of greenstone; though, at the eastern end, there is much mica slate. At the bottom of Magdalen Sound the channel turns sharply to the west- ward; and after a course of about forty miles., meets the Barbara Channel, which, as above-mentioned, commumcates with the Strait opposite to Port Gallant, and both fall-into the sea together. Magdalen Sound and its continuation, Cockburn Channel, are almost quite free from islands and rocks; but the Barbara Channel, which separates the granite from the greenstone and mica slate districts, is throughoat thickly strewed with islands, which reduce �This bird, slzhough not tam in seversl English collections, had neve? been noticed until I forwarded it to England inthe early part of the year 182?,when 'my frie?i Mr. Vigors described i? in ?he Zoological Journal for t, ho month of l?lovembzr, 182/, (vol. iii. p. 432,) under ?;he name of Mellls?ja Kis9il.
