Table LY. —Relative predominance of Ranunculus bulbosus and R. repens. 
In 1862 R. bulbosus and R. repens, taken together, were once first, five times second, 
and three times third, among the total miscellaneous herbage; in 1867 they were not 
first at all, only once second, and not third at all; in 1872 they were twice first, but 
only on the two plots brought under experiment for the first time in that year, hut 
they were three times second and once third ; in 1877 they were four times first, once 
second, and twice third. 
Notwithstanding this seeming prominence, they together only yielded a very little 
over 5 per cent, of the total produce on one plot in 1862, on one in 1867, on none in 
1872, and on two plots in 1877. The only plots on which they supplied from 5 to 6 per 
cent, were three of small total produce, viz.: 4-1 (superphosphate alone),in 1862 and 
in 1867, 12 (unmanured), and 18 (minerals and nitrogen contained in 1 ton of hay). 
The plots on which these plants came first, second, or third among the miscellaneous 
herbage, but on wdiich they did not contribute 5 per cent, to the total produce, were 
mostly characterised by meagre luxuriance; the exceptions being plot 16 (mineral 
manure and the smaller quantity of nitrate of soda), plot 14 (mineral manure and the 
larger quantity of nitrate of soda), and the two newer nitrate and mineral plots, 19 
and 20. They were absent from, or present in very small quantities, in the samples 
from the plots treated with ammonia-salts in conjunction with mineral manure where 
the gramineous herbage was luxuriant. They were, however, it is seen, more abundant 
on the nitrate plots. 
It may be observed that of the two species R. bulbosus was by far the most frequent 
and prominent; but R. repens is in relatively larger proportion on plot 1 (ammonia-
