f WI[SONIA !" AND PHYSICIANS,
New Article Sept. 21st.

At the conclusion of our last article con- sderng the vaso motor powers of the great sympa- thetic its influences upon the circulation of the blood. Without giving detailed account of the periments perfe rmed by various physioogists with view to ascertain these properties 1t only necessary to mention them to show the vast power of the cell
 gsnglonic and vital force of this great nerve upon sequele in other words upon disease itself in gen. thst properties do not belong to the sympa. thetic system independently, but that they result from the almost universal associations existing ey- eryWhere wherever their distribution occurs, be- tween this system and the cerebro spinal system that the expresgion continuity is the last of organization" used by distinguished anatomist and physiologst true in every respect Lastly, respects anatomical detail will only make men what called trophic centres of the ner- vous system. This term from the Creek to nourish
 indicates existence of certain trophic cells and nerves or depots Of nervous matter, from which arise the motor nerves that supply the muscular pow of the body. These centres to be found in the antere-ateral portions of the spinal cord and pathology has proved that in cases Of progressive muscular atropy, or wasting of the muscular struo- tures corresponding degeneration of the trophic cells and centres has been observed This Is equally true in cases of profound paralysis and another
 mod6cation of in the scIerosis of Iocomotor atax
 ia-Cells and Gangs, the generators of vital force. From what we have seen of the functional activities and the extensive powers exercised by those nerves which are largely endowed with cell and gangHon1c portions the brain meduila oblongata and spinal cord, and because of collateral conributiens which tions, we are fully justisd in ascribing to the cells and gangha of the brain, neulla oblongata, spinal ing aintang and conveying the vital forces Of the body By them all the activities of the organism impelled, whether manifesting themselves in the op
 eratons of the special in general sensation and motion, in the individual and collective func- tions of the various organs in fine. in all the
 tial powers which unite to constitute life and the phenomena of life. Brief mention may also be here made of certain remarkable cell centres. whose vital
 force is proved by experimental physiology to be pended in special directions and for speciho purpos We a1lude to what is called the 'fgenito spinal centre located in the spinal cord and opposite the zth lumbar vertsbra. From this centre proceed whose influence is felt by the organs of gen. eEation. The may be said of the celio spinal centre" and its physiological effects upon the Iris of the eye and upon vision. Lastly, that most remark able experiment of Claude Bernard by which by ir- ritation the the 4th ventricle of brain in living animal he witnessed the influences upon the liver through which its gycogenic sngar-mak- ing powers were called into operation, may be cited as among the wonder-working attributes of these nerve cells and centres To be extended Sept. 28
