ON SOME OF THE SALIENT POINTS AND DEPARTURES 

 FROM ACCEPTED TEACHING INVOLVED IN THE 

 FOREGOING VIEWS: CIRCULATION. 



THESE mainly group themselves around the doctrines of 

 circulation and nutrition, with the related subjects of 

 secretion and excretion, the histology of cell and fibre 

 generally, and that of the sympathetic and systemic nervous 

 systems particularly, the hydrostatics and hydrodynamics 

 of the lymph, or fluid called cerebro-spinal, of the central 

 cerebro-spinal nervous system and its related peripheral 

 and sympathetic extensions, and the bearing of them on 

 the causation and incidence of clinical and pathological 

 phenomena. Thus grouped, they pertain both to struc- 

 tural and functional matters, as observed in the human 

 organism in particular, but they are applicable to all dually 

 innervated and animated beings. 



The principle of circulation determines the manner 

 of occurrence and sequence of all the materio-dynamic 

 phenomena of life, and is operative alike in the uni-cellular 

 ovum, in the embryo, and in the adult body ; in the 

 first by molecular movement on atomic lines ; in the 

 second by, or along, rudimentary vessels ; and in the third 

 through the agency of elaborated and organised vascula- 

 tures, the materials moving, or circulating, in the minutest 

 physical division, or as capillary filtrate, in molecule, and as 

 vascular fluids, in mass, respectively, these three methods 

 of distribution of organic pabulum or plasma being con- 

 jointly utilised for the accomplishment of the whole 

 phenomena of nutrition, including those of metabolism
