TABLE II. 

 Observations on Volume of His-Ziegler Models. 



*In Nos. 3 and 5, the data of the volume of the models are somewhat uncertain 

 since in each a portion of the ventral body wall is deficient in the model. Cor- 

 rection was made for this by adding 5 cc. to the volume observed for No. 3, and 

 9 cc. to that for No. 5.
