1 < I) On the Composition and Nutritive Properties of Swedes, 
large on the 4th of July, as in the root before planting. The 
loss in solid substance in the root, however, was great, and the 
gain in substance in the tops was partly due to the migration 
of organic food from the bulb to the tops, and the assimilation 
of atmospheric food and mineral matter drawn from the soil. 
The last or sixth swede was removed from the land on the 2nd 
of August, and weighed and analysed the same day. 
Before planting it weighed 2 lbs. 8f ounces. 
Taken up on the 2nd of August, the bulb weighed 1 lb. 
5 J ounces, and the tops 5 ounces.

The bulb, as in the preceding period of growth, was watery, 
but the tops were very dry ; in the interval between the 4th 
of July and the 2nd of August, no doubt a large proportion of 
the tender leaves and branches dropped off, and were lost, and 
hence, the preceding results do not give a fair representation of 
the total amount of organic and mineral matter which had 
accumulated in the whole plant from the 19th of March till the 
2nd of August.
