Hellenic and |the Italic, but of the Iranian and the Indian civiliza-

(7) Finally, if the Hellenic civilization and mythology is thus to be 
mainly derived from a pre-existing Oriental or ** Pelasgian ” civiliza- 
tion, it is either from such pre-existing civilizations, or from Aryans 
such as the Kelto-Italiots, migrating northward and southward from 
Pelasgian Thrace, that the civilization of Western and Northern 
Europe would, on this hypothesis, be traced ; and a vast number of 
facts appear to make it more probable that the earlier civilization of 
Northern Europe was derived from the south than that the earlier civ- 
ilization of Southern Europe was derived from the north. 
The three conditions of a true solution of the problem either of 
Semitic or of Aryan origins appear to be these: First, the locality 
must be one in which such a new race could have ethnologically, and 
secondly philologically, arisen as a variety of the Archean stock o 
white races ; and thirdly, it must be such as to make easily possible 
the historical facts of dispersion and early civilization. And I 
venture to submit the above set of facts as not inadequately, perhaps, 
supporting the South Russian “‘ speculation as to the origin and home 
of the Aryan family.’’—J. S. STUART GLENNIE, in Nature, October 
2d, 1890. 
MICROSCOPY.! 
Lumbricus, Egg-Laying, etc.’—In spite of many individual 
variations, the egg-capsules of the various species of Lumbricus 
are, as a rule, readily distinguishable in form, color, and size. 
Those of Z. fetidus, which are laid in and about manure-heaps, 
are rather regularly fusiform, varying in color from light yellow- 
ish to dark brownish olive; they measure on the average about 
4-6 by 2-3 millimeters, The albumen is tough and jelly-like, dis- 
solves with difficulty in water, and becomes of a horn-like consistency 
after the hardening action of reagents, Each capsule contains from 
ten to sixty ova, of which not more than ten or twelve undergo de- 
velopment, and this number may be reduced to one or two, particularly 
in the winter season. The capsules of Z. communis and L. terrestris are
