The sample cut in August contained a larger amount of nutriment than
the specimen analysed in the spring; but its constituents appeared to
be much less soluble in water, and therefore, less digestible.
Professor Blyth, of the Queen's College, Cork, has more recently made
a very elaborate analysis of furze, grown in the county of Cork, which
gave results still more favorable to the plant than those arrived at
by me--probably because the specimens furnished to him were drier than
mine.
ANALYSIS OF FRESH FURZE, BY DR. BLYTH.
100 parts contain:--
_Matters readily soluble in water and easily digested._
[*] Albuminous, or flesh-forming compounds 1·68
Fat and heat-producing, or respiratory elements,
viz., sugar, gum, &c. &c. 7·83
Ash 0·83
-----
Total matters soluble in water 10·34
[* Containing nitrogen 0·265]
_Matters insoluble in water._
Oil 2·14
[+] Albuminous, or flesh-producing compounds 2·83
Fat and heat-producing, or respiratory elements 1·00
Woody fibre 28·80
Ash 3·23
-----
Total matters insoluble in water 38·00
Water, expelled at 212 51·50
-----
99·48
Total nitrogen in plant 0·71
Total albuminous, or flesh-producing compounds 4·51
Total respiratory, or heat and fat-producing compounds 8·83
Total ash 4·06
The ash contains in 100 parts:--
Potash 20·00
Phosphoric acid 8·72
[+ Containing nitrogen 0·445]
If the large per-centage of water be deducted, the dry, nutritive
matters can then be more readily compared with the amount of the same
substances in other feeding articles:--
_Composition of 100 parts of furze dried at 212°. Matters soluble in
water in the dry furze._
[*] Albuminous compounds 3·47
Respiratory elements 16·15
Ash 1·71
------
Total matters soluble in water 21·33
[* Containing nitrogen 0·546]
_Matters insoluble in water in the dry furze._
