BRITISH ZOOLOGISTS. igi 



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 

 Ccelenterate 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 suc- 

 cessfully by the celebrated Norwegian naturalist, Sars 

 (1829-40); but the observations of the Scottish zoologist 

 would seem to have been made quite independently.
