| Abstract: | SYNOPSIS. Strains of 2 syngens of Glaucoma (16) were found to have different cortical characteristics. All clones of a particular strain had approximately the same range of corticotypes, approximately the same means and high and very similar variances. The chief differences between the syngens was the corticotypic range. The patterns of variation of cortical elements of syngen 2 appeared to be primarily extensions of the patterns of syngen 1. The range of meridian numbers of different species of Glaucoma overlapped with each other and could not be distinguished by this criterion alone. |
