 Deuxieme Note sur le developpement des premieres rudi-

secondaire. C. E. LI. p. 337, 476. 

 The author concludes : 



1. That the chorda dorsalis does not exist in the first and half 

 of the second days of the formation of the embryo of birds. 



2. That the " secondary line" which has been personified under 

 that name, represents a free interval lying between the internal 

 borders of the primitive folds ; the line being inflected with the 

 folds in the formation of the cephalic hood. 



3. That this secondary line, or the interval of the primitive 

 folds, should not be regarded as the rudiment of any body what- 

 ever, since light traverses it readily when viewed under the 

 Microscope. 



4. It follows, therefore, that if the chorda dorsalis does not 

 exist in the first day of the formation of the embryo, it is not, nor 

 can he, the axis around which the primitive parts of the foetus are 

 subsequently formed.
