Table I.

The numerators in the columns give the number of species presenting varieties; the denominators the number of species in the larger & smaller genera: these fractions are all reduced to common denominator of a thousand for comparison, & are printed in larger type to catch the eye. The right-hand rows of figures in the three columns, with decimals, show the average number of varieties which each varying species has, thus the number 1.50 shows that each two varying species have on average between them three varieties.
