BARNACLES 231 



same form; in which case we should have in the young 

 Barnacle merely the first and second stages of Cypris. 

 But it is not so. Cypris does not pass through the Cyclops 

 form at all; for, according to J urine, the young when 

 hatched have the appearance of the perfect animal, though 

 varying a little in the shape of their shells. 



It is in this second form, which may be considered the 

 pupa of the Barnacle, that the animal quits its free roving 

 life, and becomes a fixture for the remainder of its days. 

 And this is a most wonderful process; so wonderful, that 

 it would be utterly incredible, but that the researches of 

 Mr. Darwin have proved it incontestably to be the means 

 by which the wisdom of God has ordained that the little 

 Water- flea should be transformed into a stony Acora 

 Barnacle. 



Having selected a suitable place for fixing its resi- 

 dence such as those massive rocks which sustain the im- 

 petuous billows on our sea-worn coasts the great project- 

 ing antennae manifest a new and unprecedented function. 

 Glands situated at their base secrete a tenacious glue, 

 which, being poured out in great profusion, cements the 

 whole front of the head to the rock, including and con- 

 cealing the antennae themselves. The cement rapidly sets 

 under water, and the animal is henceforth immovable. 



It now moults its skin once more. Another great 

 change takes place; the bivalve shell is thrown off, as 

 are also the eyes with their bent supports, and it is seen 

 to be a true Barnacle, though as yet of minute dimen- 

 sions, and with its valves in a very rudimentary condi- 

 tion. It is now the representative of a third type among 

 the Crustacean forms, for it is in effect a Stomapod; such 

 as the Opossum Shrimp (My sis), for example, with the
