THE CELL DOCTRINE. 25 



Similar, as regards the element of organization, 

 were the views of Baumgartner* and Arnold,f who 

 built up the cell wall by the apposition of globules 

 (to which the term granules would now perhaps be 

 applied!), so as to constitute a membrane within 

 which other globules (granules) remained to consti- 

 tute contents.

The error of Edwards seems to have been clearly 

 pointed out by Dr. Hodgkin, though much impor- 

 tance was still attached to the globule as an element 

 of organization (but perhaps from this time forward, 

 more in the stricter sense of the term granule), which 

 has continued, in this latter sense, to the present day. 



From the foregoing facts, it is evident that for some 

 time prior to the year 1838, the cell had come to be 

 quite universally recognized as a constantly recur- 

 ring element in vegetable and animal tissues, though 

 as yet little importance had been attached to it as an 

 element of organization, nor had its characters been
