BIOLOGICAL LECTURES. 



der Anatomic und Physiologic im Jahre 1856. Herausgegeben 

 von Dr. J. Henle, Professor in Gottingen, und Dr. G. Meissner, 

 Professor in Basel. 1 ' We have here a consolidation of interests, 

 for these Berichte, by Henle and Meissner, had already appeared 

 several years independently. They continued in connection 

 with the Zeitschrift until 1872 (literature of 1871). I have 

 been informed that the cessation of the publication was due 

 to lack of sufficient financial support. They were, however, 

 immediately replaced by a new series of Jahresberickte, edited 

 by Hoffmann and Schwalbe, later by Hermann, of Konigsberg, 

 and Schwalbe. This new series continued for twenty years, 

 and it, like its predecessor, ceased, but unfortunately has no 

 successor, except for the physiological part. But these JaJires- 

 berichte are, to a certain extent, replaced on the morphological 

 side by the Ergebnisse der Anatomic und Entwickelungsge- 

 schichte, edited by Fr. Merkel and R. Bonnet, which constitute 

 the Zweitc Abtheihing of the Anatomische Hefte. Of the 

 "Ergebnisse" three volumes (1891-93) have appeared. These 

 volumes give comprehensive summaries of groups of articles. 

 The physiological part of the Jahresbeticktc has been con- 

 tinued in a very condensed form by Professor Hermann in his 

 newly inaugurated series. 



With the progress of years the annual reports have gradu- 

 ally changed in character. The early ones were narrative in 

 form and critical in character. Thus, in the first report by 

 Johannes Muller, he relates the discussions between the sober- 

 minded, and perhaps dogmatic Cuvier, and the brilliant but 

 erratic Geoffrey Ste-Hilaire, to whom we habitually refer 

 erroneously as Ste-Hilaire ; and Muller indicates his estimate 

 of both these eminent naturalists, and finds occasion from time to 

 time to interpolate opinions, and even observations of his own. 

 But gradually the personality of the reporter is withdrawn, 

 until it has become the admitted requirement that all analyses 

 should be impersonal abstracts. In the Jahrcsberichte of the 

 present this requirement is entirely fulfilled, with only very 

 rare exceptions. 



There are also two series of s^z\2\Jahresberichte, which the 

 active worker in biology and zoology will find indispensable in
