Dr. Strong explained some exceptions which have been urged 

 to the view that the lateral line organs are innervated exclusively 

 by special roots having a common center in the medulla. 

 Among these exceptions is the innervation of a certain canal - 

 organ by a branch of the glossopharyngeus instead of by a lat- 

 eral line nerve proper. Dr. Strong showed that, close to the 

 medulla in the young dog-fish (^Sqitahis acantJiias) a small intra- 

 cranial bundle of fibers becomes detached from the lateral line 

 root, and fuses with the glossopharyngeus. This bundle retains 

 its identity, shown by greater calibre, etc. On emerging from 

 the auditory capsule the bundle becomes detached and passes 

 to a canal organ. Similar fibers described by Kingsbury in 

 Aniia, would probably be found to have the same history. 



The three other papers were read by title, the authors not 

 being present.
