We tacked in long reaches for several hours, now opening up in succession the deep withdrawing lochs of the mainland, now clearing promontory after promontory in the island district of Sleat. In a few hours we had left a bulky schooner, that had quitted Isle Ornsay at the same time, full five miles behind us; but as the sun began to decline, the wind began to sink; and about seven o'clock, when we were nearly abreast of the rocky point of Sleat, and about half-way advanced in our voyage, it had died into a calm; and for full twenty hours thereafter there was no more sailing for the Betsey. We saw the sun set, and the clouds gather, and the pelting rain come down, and nightfall, and morning break, and the noon-tide hour pass by, and still were we floating idly in the calm. I employed the few hours of the Saturday evening that intervened between the time of our arrest and nightfall, in fishing from our little boat for medusae with a bucket. They had risen by myriads from the bottom as the wind fell, and were mottling the green depths of the water below and around far as the eye could reach. Among the commoner kinds,--the kind with the four purple rings on the area of its flat bell, which ever vibrates without sound, and the kind with the fringe of dingy brown, and the long stinging tails, of which I have sometimes borne from my swimming excursions the nettle-like smart for hours,--there were at least two species of more unusual occurrence, both of them very minute. The one, scarcely larger than a shilling, bore the common umbiliferous form, but had its area inscribed by a pretty orange-colored wheel; the other, still more minute, and which presented in the water the appearance of a small hazel-nut of a brownish-yellow hue, I was disposed to set down as a species of beroe. On getting one caught, however, and transferred to a bowl, I found that the brownish-colored, melon-shaped mass, though ribbed like the beroe, did not represent the true outline of the animal; it formed merely the centre of a transparent gelatinous bell, which, though scarce visible in even the bowl, proved a most efficient instrument of motion. Such were its contractile powers, that its sides nearly closed at every stroke, behind the opaque orbicular centre, like the legs of a vigorous swimmer; and the animal, unlike its more bulky congeners,--that, despite their slow but persevering flappings, seemed greatly at the mercy of the tide, and progressed all one way,--shot, as it willed, backwards, forwards, or athwart. As the evening closed, and the depths beneath presented a dingier and yet dingier green, until at length all had become black, the distinctive colors of the acelpha,--the purple, the orange, and the brown,--faded and disappeared, and the creatures hung out, instead, their pale phosphoric lights, like the lanterns of a fleet hoisted high to prevent collision in the darkness. Now they gleamed dim and
