On the 11th February the cattle were again weighed, when their increase
was found to be as follows:--

The results of this experiment show that the animals fed upon Swedish
turnips, hay, and oil-cake, increased in weight at a rate more than
100 per cent. greater than the lot supplied with equal quantities of
Kohl-rabi, hay, and oil-cake. The superiority of the Swedish turnips was
rendered more evident by the results of subsequent experiments. Nos. 1
and 4 were not tried after the 11th February; but Nos. 2 and 3 were kept
under experiment. No. 2 was put on Swedes, and No. 3 on mangel-wurtzel,
and after an interval of a fortnight No. 2 had increased much more than
they had done on Kohl-rabi.

Specimens of the Kohl-rabi and Swedish turnips employed in this
experiment were submitted to me for analysis by Mr. Baldwin, and yielded
the following results:--
