36 QUARTERLY CHRONICLE. 
ing for locomotion, we find that throughout their whole life 
the Cypridine employ the three anterior pairs of appendages 
as locomotive organs. Now, this is exactly the case in all 
Entomostraca during the Nauplius-phase, and furnishes a 
new argument to be added to those adduced by Fritz Miller 
in favour of the derivation of all Crustacea from the Nauplius- 
form. 
Max Schultze’s Archiv fur Mikroskopische Anatomie.—The 
second and third parts of this valuable contribution to 
microscopical periodical literature have appeared, forming 
a part about equal in size to the first part. The contents 
are of equal value and interest to the former, and the illus- 
trations are copious and excellent. The sight of such copious 
and well-executed plates, eleven in number, and all but two 
of quarto size, and nearly all more or less coloured, makes 
us wonder more and more, and still more lament the strange 
condition of things that wholly prevents our doing the same 
in this country. Whether it be owing to an absolute dearth 
of artists capable of making such drawings, which, we fear, 
is very much the case, or the far higher rate of payment pub- 
lishers are compelled to submit to, the truth is no less cer- 
tain that the illustrations given in nearly all the numerous 
journals, &c., of Germany and France, but especially of the 
former country, completely put to shame our puny attempts 
in the same line. The time really appears to be coming 
when we shall be obliged to have recourse to foreign artists 
and lithographers for the proper illustration of natural his- 
tory works. It is true we may justly be proud of several 
artists in that line, who are excelled by none of any country, 
and perhaps scarcely equalled in any; but no one can deny 
that the number of good artists available for the current 
exigencies of periodical literature more especially is very re- 
stricted, and only those who know it can tell how much this 
scanty supply necessarily enhances the cost of all illus- 
trations at all worthy to compete with such as issued so 
copiously in such journals as that we are now noticing, 
Kolliker’s ‘ Zeitschrift,’ Reichert’s ‘Annalen, and several 
others which might be named, in Germany, France, and else- 
where. 
Having thus vented the natural feelings of an editor, we 
will proceed to state the contents of the present part of the 
‘ Archiv fiir Mikroskopische Anatomie.’

W. His, of Basle, entitled “‘ Observations on the Structure 
of the Mammalian Ovary.” Professor His’s observations 
refer chiefly to the mature ovary of the cow and its corpora
