and perhaps also the palpi, may claim this sense, and finds full 
confirmation of Dufour’s (37) views, and adopts as new the 
physiological possibility expressed by Hill and Bonnet,” that the 
antennz might be the seat of both senses—those of smell and 
hearing. 
As for the Crustacea, it was through Huxley,’ and still more 
through Leuckart,‘ that the evidence was afforded that Rosen- 
thal’s—also adopted as such by Blainville—olfactory organ at the 
base of the inner antenne should be regarded as an apparatus of 
hearing. Huxley therefore thought, following Farre and Robi- 
- neau-Desvoidy, that the seat of the sense of smell must lie m the 
organ discovered by Fabricius in the outer antenna, while Leydig,

complete researches on the peculiar nerve-endings which he had 
found in the antennz, also in the halteres of flies and the wings 
_ of all the other groups of insects and which he judged to be pi 
the perception of smell. But Erichson’s and Burmeister s pori 
were by Lespès, in 1858 (38), explained to be so many auditory 
-vesicles with otoliths. This view was refuted by Claparède (39) 
and Claus (13), without their deciding on any definite sense
