The other work alluded to above is the 'Rare and Remarkable Animals of Scotland,' by Sir John Graham Dalyell. This handsome work, published in 1847 by Van Voorst, in two quarto volumes, deals with the Coelenterate animals or Zoophytes of the Scottish seas, and is illustrated by beautiful coloured plates. To Sir John Dalyell is due the credit of having independently worked out the extraordinary phenomena attending the production of the great swimming jellyfishes from the little fixed Trumpet-polype or Hydra-tuba-one of the most wonderful chapters in zoological history. It is true that this subject had been previously investigated successfully by the celebrated Norwegian naturalist, Sars (1829-40); but the observations of the Scottish zoologist would seem to have been made quite independently.

EDWARD FORBES.

EDWARD FORBES deserves special mention as an admirable representative of the old and honourable race of general naturalists. He was a naturalist in the old sense of this term, rather than a zoologist; and he belonged, therefore, to a genus which is in the present epoch much less largely represented than it used to be. As a matter of course, he was essentially and principally a zoologist, or an investigator of animals. He was even a specialist in zoology, and his name will long be remembered in connection with the British Mollusca and the British Echinoderms. But he was much more than a mere zoologist; he was an accomplished botanist, and a very able geologist.

Rarely, indeed, do we now find any one man uniting in himself high excellence in these three departments. Nor can such be well expected, in view of the enormous development that these three sciences have, one and all, undergone since the middle of this century. At the same time, there is cause for regret that specialisation should now so completely rule in all departments of natural history. Less than fifty years ago, any teacher of zoology considered a knowledge of geology and paleontology-the
