Theelaborate dissections of Chiagi require to be repeatedbefore we can put implicit confidence in their accuracy. There is a point in the economy of these animals, andalso of the Sea-Urchins, to which I would direct some specimens, not in all, nor in all the examplesof any one species, we find red globules, variable as tonumber and large as to size, floating in the fluid of theaquiferous system.
