In previous papers,1 a definite method was established for the measurements of the cerebral and cerebellar surfaces. At the time, it was felt that a more thorough understanding of the cerebral surface of man could be accomplished by comparative studies in various vertebrates, from the lowest to man. This paper deals with the problem.
In the study of these measurements, the same method of technic was followed as outlined in our previous paper. In the search for methods to eliminate possible sources for error, a new projection apparatus was devised at the suggestion of Dr. Arthur Weil, which gave an enlargement of the sections from 30 to 100 times.
—The apparatus consists of a modified Universal micrographic apparatus with a photographic mechanism removed (fig. 1). The apparatus consists of a
