Eox 2. Healthy, vigorous plants, but now exhausted and wa- 
ning, 11 inches high. Slight tendency to flower. 
Box 3. In better condition than 2. More flowers showing. 
Box 4. Plants having been very strong, now waning 15 inches 
high, No flowers. 
Box 5. Plants dying off*, 14 inches high. No flowers. 
BoxG. In rather better condition than 5, 14 inches high. Two 
flower-stems. 
The plants in these boxes seem to have been generally healthy, 
but to have passed their prime at the date of observation. As 
compared with the observations at the end of June, the most 
notewwthy circumstance is the great rise in 4 (nitrate of soda) 
and the corresponding fall in 5 (ammonia and mineral). It will 
be remembered that the plants in June were so thick, and suffered 
so from drought, that no proper observations could be made on 
them at that time. 
iv. JPoa pratensis (annua). 
Plants all healthy ; those in 3 (ammonia-salts) were the best and! 
rather more forward than the rest ; 5 inches high. No tendency 
to flower in any. 
As compared with the condition in July, the plants in 2 (mi- 
neral) and in 3 (ammonia) exhibited a great rise. In 4 (nitrate 
of soda), 5 (ammonia and mineral), and 6 (ammonia and nitrate) 
'an apparent decrease. 
V. Poa trivialis (annua). 
Plants all healthy, almost all emitting stolons ; those in 3 (am- 
monia) and 5 (ammonia and mineral) the best developed ; 7 inches. 
No tendency to flower in any. All relatively in the same general 
condition as in July, except the plants in 3 (ammonia), which ex- 
hibit a considerable rise. 
vi. Bromus. 
These plants, it will be remembered, in July suffered from the 
overcrowding and drought ; and they do not seem to have reco- 
vered afterwards. In October the plants in 4 (nitrate of soda) 
and in 6 (nitrate and ammonia) were noted as the best ; those in 
5 (ammonia and mineral) seemed to have declined since July.
