The karyogranulomes, not the idiogranulomes or microsomenstratum in the protoplasm of the spermatogonia, unite into the idiosphærosome, acrosoma of Lenhossék, a protean phase, as the idiosphærosome differentiates into an idiocryptosome and an idiocalyptosome, both surrounded by the idiosphærotheca, the archoplasmic vesicle; but the idioectosome disappears in the metamorphosis of the spermatid into a sphere, the idiophtharosome. The separation of the calyptosome from the cryptosome antedates the transformation of the idiosphærotheca into the spermiocalyptrotheca.[15] [15] Of course I have made this up out of a recent number of the _American Journal of Anatomy_, 24, I. Or take a more practical if less Cratylean example. In our precious cabbage-patches the holometabolous insecta are the hosts of parasitic polyembryonic hymenoptera, upon the prevalence of which rests the psychic and somatic stamina of our fellow countrymen; for the larvæ of _Pieris brassicæ_, vulgarly cabbage butterfly, are parasitiased by the _Apantales glomeratus_, which in turn has a hyperparasite, the _Mesochorus pallidus_. It is tragic to think that the fate of a plant, the dietetic and pharmaceutical virtues of which have been so extolled by Cato, and upon which two of my Plinean colleagues of uncertain date, Chrysippus and Dieuches, wrote monographs--it fills one with terror to think that a crop so dear to Hodge (_et veris cymata!_ the Brussels sprouts of Columella) should depend on the deposition in the ovum of the Pieris of another polyembryonic egg. The cytoplasm or oöplasm of this forms a trophoamnion and develops into a polygerminal mass, a spherical morula, from which in turn develop a hundred or more larvæ, which immediately proceed to eat up everything in and of the body of their host. Only in this way does Nature preserve the Selenas, the Leas, and the Crambes, so dear to Cato and so necessary for the sustenance of our hard-working, brawny-armed Brasserii. From over-specialization scientific men are in a more parlous state than are the Humanists from neglect of classical tradition. The salvation of science lies in a recognition of a new philosophy--the _scientia scientiarum_ of which Plato speaks. "Now when all these studies reach the point of intercommunion and connection with one another and come to be considered in their mutual affinities, then, I think, and not till then, will the pursuit of them have a value." Upon this synthetic process I hesitate to dwell; since, like Dr. Johnson's friend, Oliver Edwards, I have never succeeded in mastering philosophy--cheerfulness was always breaking in.
