conceptions ; and Virchow dedicates his " Cellular 

 Pathology " to Goodsir, as " one of the earliest and 

 most acute observers of cell life." And if I may 

 again quote one neglected anatomist in support 

 of the claims of another, it may be mentioned that 

 in 1845, Goodsir, in his paper on "Centres of 

 Nutrition," which never admits the possibility of 

 cells originating otherwise than from pre-existing 

 cells, declares that " for the first consistent account 

 of the development of cells from a parent centre 

 we are indebted to the researches of Martin 

 Barry." However, we are informed by the Ger- 

 man Professor, that Remak, in his " Entwicklungs- 

 geschichte," 1852-1855, "has the merit of chiefly 

 contributing to the abandonment of the doctrine 

 of cell formation from free blastema," and that 

 the same observer established the law that cells 

 are developed by division alone in pathological 

 processes also. Then follows the remark, naive 

 enough, considering these statements about Re- 

 mak, that Virchow's "well-grounded statement 

 made in 1855, * Omnis cellula e cellula,' really 

 constitutes the basis of our present cell theory." 

 Virchow's real claim to consideration in the history 

 of cell theories is neither grasped nor mentioned, 

 namely, that by displaying in their full importance 

 the connective-tissue-corpuscles, he afforded the
