experiments, entirely justify the inference that the antennse, instead 

 of being the organs of any special sense, as they are usually regarded, 

 are, in Lepidoptera, instruments of atmospheric palpation, having 

 especial reference to the action and use of the wings in flight. This 

 conclusion has been reached contrary to my own preconceived 

 notions of the functions of those instruments ; and I believe the view 

 here taken is entirely new. Should the experiments be repeated by 

 any observer, he should be careful to select for experimental study 

 those Lepidopterous insects that are unprovided with simple eyes or 

 ocelli on the vertex at the base of the antennre. In those species 

 with ocelli on the vertex the flight is deranged scarcely at all, as 

 compared with the effect of an tennal excision on individuals unprovided 

 with these organs." This last statement of Dr. Clemens seems to 

 me scarcely to corroborate the theory propounded, for power of 

 directing the flight would seem to be due not so much to the presence 

 of antennse as to the possession of ocelli, since, if the latter be present, 

 tlie deprivation of the former does not appear to be of much conse- 

 quence. The subject clearly requires elucidation, and I hope to hear 

 of further and more conclusive experiments. " Facts Connected

 their value for reference is greatly detracted from. Hereafter, if the
