 culLurists. One result of the experiments we are now considerin,t;- 

 is to show that the ])roportion of albumenoids in turnips is U> 

 some extent intlueneed by the cliaraeter of the manures applied 

 to them, and altliouj^li we must accept with great caution results 

 obtained from an investigation conducted on so small a scale, yet 

 the ditlerences seen, on com[)aring the percentages of albu- 

 menoids, are too marked and regular to be the result of accident. 

 Arranging them as before we have the following : — 



Harelaw. 



We see from these figures that the percentage of albumenoids 

 is smaller on the plots which received dissolved phos])hates, and, 

 ilespite the heavier crop on these plots, the total amount of albu- 

 menoids per acre is less on them than on the others. In deter- 

 mining the amount of albumenoids care was taken to separate 

 from the samples all other nitrogenous substances contained 

 in them. Nevertheless it may seem a rash thing to calculate 

 to a pound the amount of albumenoid matter in an acre of turnips 

 from the combustion of a few grains of dried matter derived from 

 a few turnips ])icked at random over the acre, and so it is. The 

 numbers given cannot be better than rough ap[)roximatious, but 

 the direction in which they point is at least very decided, and 

 the probabilities ore in favour of the position that the proportion
