26 THE CELL DOCTRINE. 



really cells, seen with itjditterent instruments, and 

 further distorted by the glare of direct sunlight. 



Similar, as regards the element of organization, 

 were the views of Baumgartner* and Arnold,t who 

 were joint observers. 



They considered:]: the fundamental elements of or- 

 ganization to be the formative globule (Bildungskugel', 

 and the molecular granule (Molecular-kugelchen). 

 The first is primarily formed by a simple aggrega- 

 tion of smaller granules first represented by the gran- 

 ules of the yolk united by a formless material. The 

 " molecular granule " arises from a breaking up of 

 the " formative globule." A modification of the 

 " formative globule " out of an aggregation of which" 

 the entire embryo is first formed, is the hsematoid 

 body (Hamatoidkorper). This is a nucleated dis- 

 coid body with a distinct ring-like border (geringtes 

 Korperkern nnt einem Ringe). 



Further, " Out of these two kinds of globules and 

 out of formless material," says Baumgartner, " all 

 tissues are formed, namely, the tissue-fibres (threads) 

 out of the molecular granules, and the hsematoid 

 bodies out of the formative globules and newly- 

 formed tissue-fibres. The molecular form is not 

 everywhere equally expressed, which is owing in the 

 first place to the fact that often the molecular gran-
