INTRODUCTION. MATERIAL AND METHODS 
This paper is part of an analysis of the central connections of 
the acoustico-lateral system in teleosts, undertaken at the sug- 
gestion of Prof. C. J. Herrick. Certain’ findings upon Mauth- 
ner’s cell of more general interest than the discussion of the eighth 
and lateral line nuclei warrant the separation of this part of the 
work. 
In 1882 Mayser wrote of Mauthner’s cell: ‘‘Wenn irgend ein 
Theil des Fishgehirns, scheint mir dieses sonderbare Gebilde die 
Aufmerksamkeit der Histologen zu verdienen.’’ Beccari (’07) 
published the first thorough study of this giant among nerve 
cells and I am adding futher details which it is hoped may serve 
as a basis for a physiological-histological investigation of its 
remarkable synapses and the constituents of its protoplasm. 
Furthermore, the relationship between Mauthner’s cell, the Mil- 
ler cells and the nucleus motorius tegmenti here elaborated may 
serve to clear up the nature of Mauthner’s cell and its striking 
connections.
