per cent, and 42-2 cwt. per acre, and ash in dry matter 6*8 per 

 cent,; while without nitrate ol: soda, the means of the correspond- 

 ing five plots are, dry matter 9 per cent. 35'1 cwt. per acre, and 

 ash 6-6 per cent. The percentage of dry matter in the bulbs is 

 slightly higher, and the ash lower on the plots which got no 

 nitrate of soda, but the difference is so small as not to be worth 

 considering in estimating the value of the crop. When given 

 along with dung, nitrate of soda increased the water in turnips 

 to a slightly greater extent. The analytical numbers, if supplied 

 in Table YIII. give as a mean with nitrate of soda 8"5 per cent, 

 dry matter, and without nitrate of soda 8"7 per cent. This is 

 confirmed by the increase of ash. When nitrate is used, the 

 mean percentage in the dry matter is 7'8, and when it is not 7'5.
