The year 1884, though a bad year, gave similar 

 results. 



In 1885 full corroboration of the experiments of 1883 

 was obtained. The experiments on oats in the years 

 1883, 1884, and 1885 were conducted in a precisely 

 similar manner, and the results obtained were confirma- 

 tory of those on barley. In the first week those pots not 

 supplied with any Nitrogen were checked, and in three 

 weeks the condition of all reflected the amount of 

 Nitrogen supplied them. The conclusion as to the 

 growth of oats and barley is plainly that they respond in 

 growth with regularity to the smaller or larger amount of 

 Nitrogen given them in their food. 



PEAS, 1883 



The pots in which the peas were grown were similar as 

 to the soil and food supplied to those of the Cereals, with 

 the exception that a fewer number of seeds were germina- 

 ted and allowed to grow in each pot ; six seeds were 

 germinated of which three w^ere removed. Three pots 

 were devoted to those receiving no Nitrogen, in the rest 

 the quantities of Calcium Nitrate supplied was similar to 

 that given to the barley and oats. 



All grew well for two weeks without any apparent 

 difference ; in the third week the influence of the Nitrogen 

 revealed itself in the increased depth of colour of the 

 leaves. The plants poorly supplied with Nitrogen or 

 with none shewed of a pale yellow colour, and with much 

 smaller leaves. So far the behaviour of the peas 

 resembled that of the Cereals. "But soon a wonder did 

 appear," for in the seventh week the plants ivhick had had 

 no Nitrogen at all began to revive, and in time caught up 

 their Nitrogen-supplied brethren, one pot with the smallest 

 quantity, '164 gr. of Calcium Nitrate, surpassing in size, 

 vigour, and quantity of produce all the rest.
