600 COMPOSITION OF KOIIL-UAB! AND CATTLE-CABBAGE. 
could be relied on, with the exception of that by Dr. Anderson, 
published a few years ago in the f Highland Society’s Trans¬ 
actions.’ 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 sepa¬ 
rately. 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 com¬ 
position of both parts of the cabbage:

It wdll be observed that the outer green leaves contain 
nearly six per cent, less water than the heart and inner 
leaves. 
In the next table the detailed composition of the heart and 
inner leaves together is stated, both in the natural state and 
when dried at 212° Fall.
