In vi. {Bromus) the vigour was uniformly at a maximum (f). 
Of vii. {Trifolium pratense) the plants showed considerable 
fluctuations. Beginning high (c?), they gradually fell to h at 
the end of May, and rose slightly in June. 
Of viii. {Lotus) the plants showed a uniform medium degree of 
vigour. 
Of ix. {Trif. repens) the plants showed a uniform medium de- 
gree of vigour. 
In X. {Flantago) the fluctuations were remarkable. The plants 
throughout May were low. In June they began to rise, attained 
to the maximum at the end of the month, and sunk to me- 
dium {d) in October. 
In xi. (Achillea) a sudden rise from low to medium was ob- 
served ; the position was maintained throughout June ; but in 
October it was noted that the plants had attained nearly to the 
maximum. 
In xii. (Car urn) a medium degree of vigour was observed, with 
slight fluctuations. 
The evidence afl'orded by these experiments, so far as it goes, 
would seem to show that nitrate of soda is useful to Grrasses, less 
so to Clovers, of advantage to Flantago and Achillea, but of little 
use to Garum. 
Boa: 5. Mineral and Ammonia. 
In the case of i. (Bacti/Us) the plants at first showed a maximum 
(f), declined to medium (d, c) during June, but manifested a slight 
increase in July and October. 
In ii. (Anthoxanthim) the vigour was uniformly high, wdth a 
slight decline in July. 
Of iii. (Lolium) the plants were uniformly high, but after the 
cutting in July they seem to have declined. 
Of iv. (Boa annua) the plants were uniformly high till after the 
cutting, when they declined. 
Of V. (Boa trivialis) the plants were uniformly high throughout. 
In vi. (Bromus) fluctuation was noted ; but throughout a high 
average was maintained. 
In vii. (Trifolium pratense) a maximum (/) was noted till the 
cutting, after which the plants declined, till in October they de- 
scended to b. 
In viii. (Lotus) a high degree with but slight fluctuation was 
noted throughout.
