We have already said that it would be unsafe to draw from 
these limited analyses any decided conclusions in respect to the 
influence of soil or varietjj on the mineral composition of the 
plant. But at the same time they are sufficient in number to 
afford perfectly satisfactory data for the average composition of 
the ashes of the grain and straw of peas and beans ; and perhaps 
we could not better conclude this Report than by placing for 
comparison, in a tabular form, the mean analyses before given.
