[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. —
