This morning I made an excursion to the northward, in order to examine a well, reported to be of a mineral nature. It is situated about half a quarter of a mile from Old Pithoea, and seemed to me only a common cold spring, having no taste, nor could I perceive any ochre about it, nor any silvery film on its surface. In the road to this spring stands a steep hill called _Brevikberget_, which I climbed with great difficulty. In the clefts of the rock lay several wings of young ravens and crows, with feet of hares, &c. "See," said I to my companion, "here has been the nest of an Eagle Owl!" On arriving at the next crag, a little higher up, we discovered a pair of birds of this species (_Strix Bubo_) sitting in a hollow of the rock. Their eyes sparkled like fire, for the iris in each of them was luminous in itself, like touchwood, glow-worms, or rotten fish. These birds were as large as young geese. I durst not venture to attack them with my hands; but approaching them with a stake, I then first perceived they were almost full grown, though not yet able to fly. The extent of their wings when spread was four feet; their colour blackish, with red-brown spots; their plumage very soft down, of a blackish hue tipped with white, mixed with sprouting quills. The smaller feathers were underneath of a reddish brown, marked with very narrow curved lines. The hue of the larger feathers, especially of the breast, where they were most apparent, was a brick colour, each being marked with a black indented longitudinal stripe. The feathers over the eyelids were small and black; upper part of the cheeks dark coloured, lower whitish. The wings and tail were not yet come to their full growth, but their quill feathers were blackish, with roundish red-brown spots. Feet like those of a hare, red-brown and downy, with naked claws. Bill black, the cere or membrane at its base black, accompanied by whitish whiskers. Nostrils at the fore part of the cere, roundish, separated by an oblique partition. Throat white. Iris of the eye round, large, saffron-coloured, with a very large blueish-black pupil. The ears were large, and I could have wished they had fallen under the inspection of an able anatomist, as they would certainly have afforded him matter for curious observation. The bones called the _stapes_, _incus_, &c., as well as the _cochlea_, were of large proportions. The eyes also were large and prominent, dilated at their base like an onion. When the white outer coat was removed, which was easily accomplished, the cornea appeared of considerable thickness, in which, when in a room, external objects were very accurately delineated, but not so abroad. The crystalline lens was remarkably soft, and scarcely of more consistency than the vitreous humour. The _tunica arachnoidea_ was very conspicuous, filled with innumerable vessels, and of such firmness as to be very easily separable from the cornea. In the middle, near the optic
