THE CELL DOCTRINE. 51 



" § 83. The nuclei whicli various observers have 

 found lying among the fibres of various tissues, have 

 been considgred by them as the ' remains of cells.' 

 This may have been the case, but so far from think- 

 ing with those observers, that the nuclei in question 

 were ' destined to be absorbed,' I am disposed to con- 

 sider that they were sources from which there would 

 have arisen new cells." 



Without doubt, we can say, as did Goodsir,* in the 

 above by Martin Barry, we have the " first consistent 

 account of the development of cells from a parent 

 centre, and more especially of the appearance of 

 centres within the original sphere." Nothing more 

 definite, or directly to »the point, could be desired, 

 and we think it may be justly said of Barry, that 

 he completed the expression of the cell theory in- 

 augurated by Schleiden and Schwann, in modifying 

 the mode of origin to conform to most recent obser- 

 vation. 



PROF. JOHN GOODSIR, 1845. 



In 1845, Prof. John Goodsir published his paper on 

 " Centres of Nutrition, "f in " Anatomical and Patho- 

 logical Observations," in which he clearly grasped the 

 two important principles of the modern Cellular Pa- 

 thology ; first, the activity of these centres (nuclei), their 

 power " to draw from the capillary vessels, or from 

 other sources, the materials of nutrition, and to distrib- 

 ute them by development to each organ or texture after 

 its kind ; " second, the origin of such centres or nuclei
