female fish, especially for the male; and showed me further, that the hard-shelled spawn of this creature may, when well washed, be eaten raw, and forms at least as palatable a viand in that state as the imported caviare of Russia and the Caspian. There were instances in which the common crow acted as a sort of jackal to us in our lump-fish explorations. We would see him busied at the side of some fuci-covered pool, screaming and cawing as if engaged in combating an enemy; and, on going up to the place, we used to find the lump-fish he had killed fresh and entire, but divested of the eyes, which we found, as a matter of course, that the assailant, in order to make sure of victory, had taken the precaution of picking out at an early stage of the contest. Nor was it with merely the edible that we busied ourselves on these journeys. The brilliant metallic _plumage_ of the sea mouse (_Aphrodita_), steeped as in the dyes of the rainbow, excited our admiration time after time; and still higher wonder used to be awakened by a much rarer annelid, brown, and slender as a piece of rope-yarn, and from thirty to forty feet in length, which no one save my uncle had ever found along the Cromarty shores, and which, when broken in two, as sometimes happened in the measuring, divided its vitality so equally between the pieces, that each was fitted, we could not doubt, though unable to repeat in the case the experiment of Spallanzani, to set up as an independent existence, and carry on business for itself. The annelids, too, that form for themselves tubular dwellings built up of large grains of sand (_amphitrites_), always excited our interest. Two hand-shaped tufts of golden-hued setæ--furnished, however, with greatly more than the typical number of fingers--rise from the shoulders of these creatures, and must, I suspect, be used as hands in the process of building; at least the hands of the most practised builder could not set stones with nicer skill than is exhibited by these worms in the setting of the grains which compose their cylindrical dwellings--dwellings that, from their form and structure, seem suited to remind the antiquary of the round towers of Ireland, and, from the style of their masonry, of old Cyclopean walls. Even the mason-wasps and bees are greatly inferior workmen to these mason _amphitrites_. I was introduced also, in our ebb excursions, to the cuttle-fish and the sea-hare, and shown how the one, when pursued by an enemy, discharges a cloud of ink to conceal its retreat, and that the other darkens the water around it with a lovely purple pigment, which my uncle was pretty sure would make a rich dye, like that extracted of old by the Tyrians from a whelk which he had often seen on the beach near Alexandria. I learned, too, to cultivate an acquaintance with some two or three species of doris, that carry their arboraceous, tree-like lungs on their backs, as Macduff's soldiers
