former variety (A), and one of the latter variety (B). The plots, 

 which were prepared and planted on Jnly 1st, were each 20 inches 

 square, cut oif by sinking four slates, the soil being prepared 

 12 inches deep. They were treated with the same kinds of ma- 

 nure, and used in the same proportions, as those employed in the 

 series of experiments with grasses and other pasture plants now 

 in progress, the manures having been kindly furnished by Mr. 

 Lawes and Dr. Gilbert. 



Plot 1 consisted of unmanured soil of a loamy quality. 



Plot 2. The same, manured with a purely mineral mixture. 

 (For particulars, see Report of Meeting, August 4, 1808.) 



Plot 3. The same, manured with ammonia only. 



Plot 4. The same, manured with nitrate of soda only. 



Plot 5. The same, manured with ammonia and mixed mineral 

 manures. 



Plot 6. The same, manured with nitrate of soda and mixed mi- 

 neral manures. 1 

 The plots were examined on the IGth of August, and again on 

 the 6th of September, when the following notes were made : — 



Variegated Zonal Pelargonium — Mrs. Pollock. 



Plot 1. Plants growing freely, about equal to those in plots 5 

 and 6. 



Plot 2. Not so free or vigorous as those in plot 1. 

 Plot 3. Similar to plot 2. 



Plot 4. The least developed, and not showing any of the im- 

 proved colouring which often accompanies stunted growth. 



Plot 5. Plants growing vigorously, about equal to those in 

 plot 1. 



Plot G. Similar to plot 5. 



Of the above, plots 1, 5, and G were the best coloured, 6 being, 

 perhaps, a little superior to the others ; but, generally, it could 

 not be affirmed that there was any positive improvement upon 

 the normal colouring of healthy plants. 



Bedding Pelargoniums'. — A. Herald of Spring ; B. JSTorah 

 (salmon-coloured varieties). 



Plot 1. These plants grew taller and made most leaf-growth, 

 but produced thinner and smaller flower-trusses. 



Plot 2. Inferior to those in plot 1, both as to growth and 

 flowering.
