halten. Herr R., welchem bekannt war, daß ich mit Untersuchungen 
über das Nervensystem der Nematoden beschäftigt bin, hatte mir mit- 
getheilt, daB er die Musculatur der Nematoden zum Thema seiner 
Untersuchungen genommen habe. Gegen Ende August 1882 erfuhr 
ich jedoch, ebenfalls in persônlicher Unterhaltung, daf er letztere auch 
auf das Nervensystem ausgedehnt habe. Das eigenthümliche Schwei- 
gen, mit welchem derselbe meine miindlich mitgetheilte Anschauung 
vom Nervenverlauf im männlichen Hinterleibsende der Ascariden an- 
hôrte, drängte mich das, was ich — Jahre vorher — meinen Zuhôrern 
vorgetragen hatte, zu publiciren. 
Herr R. hat außerdem absprechende Bemerkungen zu einigen 
andern Ergebnissen meiner Untersuchungen gemacht, deren Beur- 
theilung ich aber in die Hände unparteiischer und mehr berufener 
Fachmänner lege.
