address delivered at tlie thirtieth annual meet- 

 ing of the American Neurological Association 

 held at St. Louis, September 15, 1904, by the 

 president. Dr. Frank R. Fry. Dr. Fry briefly 

 reviewed the gi-owth of neurology as a spe- 

 cialty, dwelling particularly on the part played 

 by America in its later development, and sum- 

 marizing the history of the organization. In 

 an article on ' Purulent Myelitis, Focal and 

 Disseminated,' Dr. Joseph Collins presents an 

 interesting case of this uncommon disease il- 

 lustrated by numerous cuts. In an elaborate 

 discussion of ' Hallucinations ' Dr. William 

 A. White, after criticizing some current dif- 

 ferential definitions of hallucinations and illu- 

 sions, together with various theories explana- 

 tory of the latter, sets forth that arrived at by 

 himself and Dr. Sidis, namely, the ' peripheral 

 theory,' which refers the origin of hallucina- 

 tions to a pathological process in the end organ.

 ical Society for March 24, 1904, are reported
