A comparison of the preceding results with the analyses of 
swedes, mangolds, and tmnips, shows that theoretically Kohl-rabi 
is much more nutritious than white turnips, and fully equal, if not 
superior, to swedes and mangolds. These remarks, however, I 
would remind the reader, apply only to the specimens which I 
had an opportunity of examining. Future examinations, and, 
above all, practical feeding experiments, are required to establish 
fully the comparative feeding value of Kohl-rabi. 
I may remark Avith respect to the Kohl-rabi, that it is an ex- 
cellent food for milch-cows, inasmuch as it produces much and 
good milk. The butter made of such milk has a pleasant taste, 
altogether unlike the disagreeable flavour that characterizes butter 
made fi-om the milk of cows fed upon turnips.

As yet not many complete analyses of field-cabbage have been 
published. I do not recollect having seen any one that could be 
relied on, with the exception of that by Dr. Anderson published 
a few years ago in the Highland Society's Transactions. It 
appeared to me, therefore, desirable to make a full analysis of 
this useful crop. The specimen examined in my laboratory was 
grown on the farm attached to the Royal Agricultural College, 
Cirencester. A preliminary trial showed that the outside leaves 
contained much less water than the inner, for which reason both 
were examined separately. The whole cabbage was divided into 
two parts : the one consisting of the outer green leaves, the other 
of the heart with the paler inner leaves attached to it. 
The following tabular results represent the general composition 
of both parts of the cabbage : —
