GANGLION CELLS 



An effort to reach some conclusion as to the character of the 

 ganghon cells of the termmalis in the turtle embryos was made by 

 comparing them with cells of other ganglia, cranial, spinal and 

 sympathetic. The gasserian, sphenopalatine, and ciliary ganglia 

 were studied in the head region. The spinal ganglia, beginning 

 with the first thoracic, and the sympathetic chain ganglia were 

 studied in the body region. Measurements were made of the 

 nuclei with the aid of an ocular micrometer, the results of which 

 are indicated in table 1. The cells measured were taken at 

 random. The only selection exercised was in measuring nuclei
