612 REPORT— 1897. 



the discoveries has been published by the Society of Antiquaries in 

 ' Archpeologia,' Iv. pp. 409-430. 



It is proposed during the current year to excavate the two insulce 

 (XVI. and XVII.) extending from insula III. as far as the south wall. 



Although more than half of the area (100 acres) within the walls has 

 now been systematically excavated, and with most important results, the 

 Committee desire to point out that there is still several more years' work 

 to be done before the Romano-British city can be regarded as completely 

 disclosed. They therefore ask to be reappointed, with a further grant of 

 40^. The whole of the grant made in 1896 has been expended. 



F^mdional Activity of Nerve Cells. — Report of the Committee, consisting 

 of Dr. W. H. Gaskell (Chairman ami Secretary), Mr. H. K. 

 Anderson, Professor F. Gotch, Professor W. D. Halliburton, 

 Professor J. B. Haycraft, Dr. J. N. Langley, Professor J. G. 

 McKendrick, Dr. Mann, Professor Burdon Sanderson, Professor 

 E. A. SchAfer, Professor C. S. Sherrington, and Professor A. 

 Waller, appointed to investigate the changes ivhich are associated 

 u'ith the Functional Activity of Nerve Cells and their Peripheral 

 Extensions.

It was felt by the Committee that the most hopeful chance of the dis- 

 covery of the changes which the nerve cell and nerve fibre undergo during 

 activity was by means of investigations in two directions, viz., the changes 

 in histological appearance and in electrical reactions. In furtherance of 

 this object the Committee requested Dr. Mann to investigate the histo- 

 logical appearances in nerve cells after long continued activity ; Professor 

 Boyce to investigate the histological changes in nerve cells resulting from 

 the action of drugs ; and Mr. Lloyd, the histological changes in nerve 

 fibres under the influence of reagents. For the investigation of the 

 electrical phenomena Professor Waller undertook the electro-physiology 

 of isolated nerve ; and Professor Gotch, the investigation of the electrical 

 changes in the spinal cord and roots during activity. 



In addition to these two main branches of the inquiry there were 

 numerous other important questions which required an answer ; among 

 these the meaning of the medullation of nerve fibres and its relation to 

 their functional activity. The investigation of this problem was entrusted 

 to Mr. Anderson. Again, the cells of the sympathetic nervous system
