In a few days the water, poured carefully to these specimens, became clear as pale green crystal, the green tinge being too slight to obscure the colour of any object seen through its medium.
From these weeds alone, before any supply of Zoöphytes or Molluscs were intentionally added, a whole host of minute animal life swarmed forth; some, doubtless, issuing from eggs newly hatched; others from the shelter of the matted ramifications of some of the sea-weeds, in which they had been taken, as in a net. Among these swarming creatures were Annelids of the genus Syllis, Rissoæ, and other minute shell-fish, but principally Isopodous and Entomostracous Crustacea, many of them being so minute as not to be perceived without the use of a powerful lens.

There were thus above seventy specimens, animal and vegetable, already in the tank, without counting the swarms of smaller creatures, some the young of large species, daily increasing in size; yet, our bold experimentalist, anxious to conquer his “Russia” at one grand invasion, still poured in fresh specimens. These consisted of:—
| FISH. | |

These additions brought the collection up to above a hundred specimens, and no doubt the tank made a glorious show; but Mr. Gosse, though the Napoleon of his specialty, was forced to acknowledge that there was an “impossible.” Although his collection was superb, and his interesting tank did not look over-crowded, yet he soon discovered that a forbidden limit had been passed, and that the creatures of the ocean that have yards—fathoms—of their native element to their own separate share, cannot accommodate themselves to the allotment system, in the proportion of a square inch to each individual.
