I see Lindley makes so many divisions that there would not be enough in each for an average.

I send the table of the Labiatae for the chance of your being able to do this for me.

You might draw oblique lines including and separating both large and small genera.

I have also divided all the species into two equal masses, and my rule holds good for all the species in a mass in the six volumes; but it fails in several (four) large Orders--viz.

Labiatae, Scrophulariaceae, Acanthaceae, and Proteaceae.
