numerous fibers and branches. My preparations by the better 

 neural method that are favorable for tracing it are not numer- 

 ous. Fig. 16 represents one in which the fibers shown are all 

 that are impregnated in this region. Here a fiber is seen com- 

 ing in from the nerve and at some distance from its entrance 

 bending aside to a glomerula from which another fiber passes 

 out and then on towards the proto-cerebron. The other fiber 

 soon after entering breaks up into three branches one of which 

 terminates in a glomerula. The tuft-like termination was not 

 seen when the drawing was made, but after the latter was fixed 

 to the plate a re-examination of the specimen brought it to 

 light, but with scarcely sufficient distinctness to be drawn with 

 a camera. 



If one is to credit, as one must, the long list of writers 

 since the time of Newport dealing with the antennae anatomi- 

 cally and physiologically, one must conclude that these organs 

 have at least two, and in many cases, if not always, three differ- 

 ent functions. That they are both tactile and olfactory has 

 long been known, and recently Child ( 94.) has brought forth 

 very good anatomical reasons for their being also auditory. 

 Such being the case one might expect to find as many different 

 kinds of terminations in the antennal morula. 



There is a striking resemblance between the tufts forming 

 the glomerulae and those forming the olfactory glomerulee in 

 mammals as described and figured by Retzius (92^); and, since 

 in the ventro-cerebron where sensory fibers from the oral nerves 

 undoubtedly terminate no such glomerulae are found, one may 

 be very easily led to the conclusion that the glomerulae are for 

 olfactory terminations. But I am unable to produce evidence 

 of other terminations and must for the present conclude that 

 the glomerulae are formed by the terminations of all kinds of 

 fibers from the antennae. This conclusion is supported by the 

 fact that the tubercles of the central body, in which fibers from 

 the ocellar nerves apparently terminate, and the ocellar glome- 

 rulae have a very similar appearance. 



Another kind of fiber is shown along with its cell in fig. 

 15. This was found in the posterior ventral regions and bears
