fir die Morphologie des Hirns bei niederen Vertebraten,” 
which appeared in the ‘ Anatomischer Anzeiger,’ Bd. ix, Nos. 
5 and 6, p. 152, Rud. Burckhardt began a discussion, which 
was vigorously carried on in the same journal by Studnicka 
and Rabl-Riickhard. Before the Anat. Gesellschaft W. His 
discussed the same subject. His paper was subsequently 
published in the ‘Arch. f, Anat. u. Entw. ; 1898, p. 157, “ Uber 
des frontale Ende des Gehirnrohres.” In the same number 
His published a paper on nomenclature, ‘ Vorschlage zur 
Eintheilung des Gehirns.” 
C. von Kupffer’s contribution to the argument is found in 
his ‘Studien zur vergl. Entwickelungsgeschichte des Kopfes 
des Kranioten,’ and also in the report of the Anat. Gesellschaft. 
An admirable summary of Burckhardt’s views is found in 
his paper entitled “‘ Der Bauplan des Wirbelthiergehirns” in 
‘Morpholog. Arbeiten, hrsg. v. G. Schwalbe, Bd. iv, 1894, 
p. 131. 
Critical digests of the literature will be found in Froriep’s 
paper, “‘ Entwick. des Kopfes” (‘ Ergebnisse der Anatomie und 
Entwickelungsgeschichte,’ hrsg. v. F. Merkel und R. Bonnet, 
Bd. iii, 1893); also the papers of Sorenson and Herrick in 
recent numbers of the ‘ Journal of Comparative Neurology.’ 
To Dr. L. Edinger I am indebted for a copy of his paper 
entitled “Die Faserung aus dem Stammganglion Corpus 
Striatum ” (‘ Verhdl. Anat. Gesellschaft,’ May, 1894), contain- 
ing an account of the “ radiatio strio-thalamica.”
