Fish, Terminology of the Nerve Cell. 175 



convenient correlative spongiocyte may be used for the glia or 

 neuroglia cell. There is no inherent objection in retaining the 

 prefix of the term applied to the embryonic cell ; for in the 

 adult there is still an analogy, more or less modified, to the ear- 

 lier condition. 



Each increment to the sum total of human knowledge is 

 welcome, but it cannot be of great permanent value if clothed in 

 terms which admit of more than one interpretation, and for this 

 there can be no remedy but the universal employment of a clear 

 and consistent terminology. * 



*Since the above was written I have found in the part on Nervenlehre of 

 Dr. August Rauber's Lehrbuch der Anatomie des Menschen, Leipzig, 1894, that 

 he uses the terra neurit in the same sense for which neurite is proposed, and that 

 in order to avoid undesirable confusion he uses the terra neura for a nerve unit in 

 place of Waldeyer's neuron. Since neura is the plural form of neuron, it is ob- 

 jectional because it is etymologically incorrect for a single nerve unit.
