[calculations not transcribed]
In Proportion to the larger genera, these genera of 4 each, ought to have had 12.2 species presenting vars, but really they present 16, ie they vary more proportionally than the larger genera, above 4 all taken together.)
[240v]
List of genera with 3 species
[List and calculations not transcribed]
According to the standard of the genera with only 1 & 2 species the genera with 3 species ought at least to have had 8.4 species with vars, but they have only 6 species.—
General conclusion from Both sides of these Pages
Genera with 4 vary too much & genera with 3 vary too little according to my theory. —
