THE CELL DOCTRINE. 27 



ules more or less fuse together, and second, that 

 formless material surrounds the molecular granules 

 and makes their ontline indistinct. The theory here 

 brought forward of the fundamental form of organi- 

 zation in animals may well he called the globular 

 theory." P. 83. 



It is evident that the " formative globule," or at 

 least the modification of it called the Hosmatoidkor- 

 per, is nothing more nor less tlian the nucleated cell, 

 which,however, Baumgartnerdidnot admit, contend- 

 ing as late as 1842 against the cell doctrine ; asserting 

 also (p. 40, op. citat.) that in the development of tissues 

 the formative globule never divides to form two, in 

 other words, that there is no such thing as cell di- 

 vision.* 



Arnold also says thatf all fluid and solid parts of 

 the human body are resolvable first into a fluid or 

 half fluid material of no determinate form, and sec- 

 ond, into granules which are more or less completely 

 spherical-, and in all solid structures appear for the 

 most part as minute globules. The granules, which 

 are the second more important element, occur not 

 only in all fluids and solid parts of the completely 

 formed human organism, but they are also the origi- 

 nal and essential constituents of the human embryo. 

 Out of these by their aggregation are formed the.most 

 complex tissues of the organism. 



* To the student desiring to pursue further this very interesting 

 subject, with the argument against the cell theory by Baumgart- 

 ner, I would recommend the perusal of the very interesting " Bei- 

 trago zur Anatomie und Physiologie " alluded to.
