 records more complete, and even were there more substantial agree-

 and a full discussion of the significance of its resemblances and pecu- 

 liarities would be profitable before a comprehensive society like this

 foundations of neurology are laid in the primary schools, and when

 ing, dissecting and describing the brain of a shark.
