THE MOVEMENT OF THE CELL. 129 



Here we may well cry halt to the remotely 

 forecasting imagination (which Tyndall, 

 however, makes an important part of the sci- 

 entists' intellectual outfit), and come down to 

 the present state of our science. As already 

 indicated the Cellular Biocosmos falls natur- 

 ally into the following three divisions, which 

 form a process together : 



(I) Cytology the science of the cell in 

 its immediate manifestation. 



(II) Pathology in general known as the 

 science of disease; the negative phase of the 

 cell. 



(III) Hyglology the science of health, 

 the restoration of the cell from its negative 

 condition. 



The present is a vast field, embracing as it 

 does the whole subject of medicine and heal- 

 ing, with its numerous theories and practices 

 all more or less in a state of bitter strife. 

 Of course there can be no attempt here to 

 give even a slight survey of the merits or 

 demerits of this conflict of the doctors of 

 physic, in which also the doctors of divinity 

 and even divinity without the doctor have 

 mingled. This field more than any other per- 

 haps, may be deemed the present battle- 

 ground of the Biocosmos on account of the 

 many combatants, the great diversity of their 

 positions, and the frequent fierceness of their
