by appropriate remedies. " Wherever/' says 

 Professor Carpenter, " the precautions obviously 

 suggested by the knowledge of the nature of the 

 disease afforded by the Microscope, have been 

 duly put in force, its extension has been kept 

 within comparatively limited bounds." 1 Pro- 

 fessor Goodsir of Edinburgh stated some years 

 ago, that a peculiarly severe and unmanageable 

 affection (sarcina ventriculi), was connected 

 with what appeared under the Microscope to be 

 parasitic vegetables of low organization ; and 

 Mr. Quekett recently remarked that remedies to 

 destroy vegetable life might probably arrest a 

 complaint hitherto almost always fatal. 2 Dr. 

 Mantell, again, suggests that as the cell is the 

 extreme point to which we can trace the life of 

 animals and vegetables, and that, as their many 

 important processes are performed through the 

 agency of cells, there in the cell disease may 

 probably be most early detected, and in the cell, 

 too, remedial measures may be most beneficially 

 employed. 3
