case of the Lotus and the Milfoil, the second growth of which, in the 
unmanured boxes, in October was superior to that of all the rest. 
Box 2. Mineral Manure. 
The plants of i. {Dactylis), ii. (Anthoxanthmi) , iii. (Zolium), v. 
(Poa trivialis), and vi. (JBromus),\were uniformly low («, h). In 
JPoa pratensis (annua) the vigour was low at first, but exhibited a 
sudden rise in July, so that in October the plants had attained 
nearly to the maximum degree. 
In Trifolmm pratense the vigour Avas high throughout; in 
Lotus, low ; in Trifolium re])ens, high throughout. Of x. (Flan- 
tago) the plants declined in vigour. In xi. (Acliilled) the vigour is 
noted low till June ; but in October the plants had attained a 
high degree of luxuriance ; and in xii. (Carum) a uniformly low de- 
gree was observed. The general result here seems to be, that 
the herbage of the grasses was not materially benefited by the 
mineral manures ; the two trefoils, on the other hand, luxuriated 
in them. There are, however, certain discrepancies, as in the 
case of Foa annua and Lotus connculatiis, the one high, the other 
low — conditions the reverse of those observed in their near allies 
respectively. 
Box 8. Ammonia-salts. 
The twelve plants treated with these manures exhibited re- 
markable fluctuations in the case of each box, and also great va- 
riation when the plants in one box were compared with those in the 
others. Of i. (Dactylis) the plants showed a high degree of vigoui.' 
at first (e), and then declined to medium (<?), where they re- 
mained till the end of May, when they rose to their former level ; 
and at the end of July they had attained the maximum (/'), in 
which condition they remained till October. 
In ii. (AntlioocantJium) considerable fluctuations were observed. 
Beginning low (a), the plants attained a medium degree of vi- 
gour (d) in the middle of May, experienced a decline in the end 
of May, rose again in June to high (e), while in October they 
were noted at c. 
In iii. (Lolium) much less fluctuation was noticed ; the plants 
throughout maintained a medium degree of vigour (<?, d)^ de- 
clining rather towards the end of the experiment. 
Of iv. (Foa pratensis (annua)) the plants were also of medium 
vigour generally, but at the close of the experiment manifested
