In albuminous matter, which is especially valuable for milch 
cows, it has nearly double the proportion contained in 
meadow hay. Bran also undergoes a great improvement in 
its flavour by steaming, and it is probably improved in its 
convertibility as food; it contains about 14 per cent, of 
albumen, and is peculiarly rich in phosphoric acid, nearly 
3 per cent, of its whole substance being of this material. 
The properties of rape-cake are well known ; the published 
analyses give it a large proportion (nearly 30 per cent.) of 
albumen ; it is rich in phosphates and also in oil. This is of 
the unctuous class of vegetable oils, and it is to this property 
that I call particular attention. Chemistry will assign to 
this material, which has hitherto been comparatively neglected 
for feeding, a first place for the purpose of which I am 
treating. If objection should occur on account of its flavour, 
I have no difficulty in stating that by the preparation I have 
described I have quite overcome this. I can easily persuade 
my cattle (of which 60 to 80 pass through my stalls in a 
year), without exception, to eat the requisite quantity. Nor 
is the flavour of the cake in the least perceptible in the milk 
or butter. 
During May, my cows are turned out on a rich pasture 
near the homestead, towards evening they are again housed 
for the night, when they are supplied with a mess of the 
steamed mixture and a little hay each morning and evening. 
During June, when the grasses are better grown, mown 
grass is given to them instead of hay, and they are also 
allowed two feeds of steamed mixture. This treatment is 
continued till October, when they are again wholly housed. 
The results which I now proceed to relate are derived from 
observations made with the view of enabling me to under- 
stand and regulate my own proceedings . — Journal of the
