NOTE I. (Page 10.) 



" Tn our previous cursory reference to the wonderful 

 transformations undergone by the Barnacle tribe, the 

 reader would understand that these assertions rest upon 

 the evidence of modern naturalists" In fact, prin- 

 cipally upon the evidence of Mr J. V. Thompson, 

 of Cork,* who states, that he watched one of these 

 singular little creatures through the wonderful changes 

 of its existence. We may say, with Mr Kirby, in his 

 " Bridgewater Treatise " on the History, Habits, and 

 Instincts of Animals, that the thing is not impos- 

 sible, for with God all things are possible, but it ap- 

 pears in the highest degree improbable. " That a loco- 

 motive animal, gifted with eyes and legs, should, by 

 an extraordinary metamorphosis, in its perfect state, 

 become a Barnacle, without head, eyes, or locomo- 

 tive organs, can never be admitted, till confirmed by 



* Mr Spence Bate has also endeavoured to corroborate Mr 

 Thompson's theory. See " Mag. Nat. His.," 1851, xiii. 8.
