less watery and no doubt also more nutritious than that of the 

 purple-top. 



The following table gives the composition of these two varieties 

 of Kohl-rabi in a perfectly dry state :

A comparison of the preceding results with the analyses of 

 swedes, mangolds, and turnips, 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 with 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 from the milk of cows fed upon turnips. 



Composition of Cattle-Cabbage. 



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
