NOTE. 



Whilst this volume has been passing through the press, 

 the following interesting fact, with reference to the duration 

 of life among the ActinidcB, has been kindly communicated 

 to me by Mr. Van Voorst. He says : " My friend the 

 Rev. Dr. Pollexfen, who is now here, tells me that he saw a 

 few days ago, in the possession of Professor Fleming at 

 Edmburgh, an Actinia mesembryanthemwn, taken at North 

 Berwick, in 1828 (and at that time imagined to be seven 

 years old), by the late Sir John Daly ell, who kept it in con- 

 finement till his decease, and in whose work, ' Piai'e and 

 Remarkable Animals of Scotland,' published in 1848, there 

 is a figure of it. This animal must, therefore, be about 

 thirty-five years old, twenty-eight years of which it has 

 sustained fife in confinement."
