vii. Trifolium pratense. 
Plants all healthy and in seed ; those in box 6 were the strongest, 
those in box 2 (mineral) next. The most noteworthy point was 
the opposite character of the plants in 5 and 6. Thus in box 5 
(ammonia and mineral) the plants had relatively declined very 
much since July, while in box 6 a corresponding relative im- 
provement had taken place. Ko corresponding fluctuations were 
observable in 2 and 3 or in 3 and 4. 
viii. Lotus. 
All healthy and vigorous, so much overgrown that accurate 
comparative observations were difficult. All were in seed. 
The contrast between the condition of the plants in the unma- 
nured box ] in October and in July was striking ; in July it was 
registered at a minimum, but in October it was at / (maximum). 
Box 6 also presented a great difference ; in July the plants were 
registered at but had fallen to a in October. 
ix. Trifoliwn rejpens. 
Plants healthy ; those in the unmanured box the least vigorous. 
Those in box 5 (ammonia and mineral) were the best-developed ; 
but little tendency to flower in any of the plants ; and in box 2 
none at all. The contrast to the condition in July was remarkable : 
thus in the plants in 2 (mineral) a great decline was observable, 
in those in 3 (ammonia) a slight rise, in those in 4 (nitrate of 
soda) a greater rise. 
X. JE^lantago. 
Plants healthy in all cases ; all in flower or seed. Plants in 
boxes 5 and 6 the most vigorous ; those in box 2 the least so, 
both as regards leaf and flower. As compared with the condition 
in July, but little diff'erence is worthy of being noted, except in 
the case of box 4 (nitrate of soda), the plants in which box seem 
to have relatively deteriorated. In the plants in 5 and 6 there was 
a slight increase of vigour as compared with the state in July. 
xi. Acliillea. 
Plants all healthy and vigorous, all with strong flower-heads. 
The plants in box 1 were in all ways the best, those in box 2 the 
next in degree, the rest nearly alike.
