NUTMEG (from " See also: evergreen See also: tree, about 5o to 6o ft. high, found See also: wild in the See also: Banda Islands and a few of the neighbouring islands, extending to New See also: Guinea
.
Nutmeg and mace are almost exclusively obtained from the Banda Islands, although the cultivation has been attempted with varying success in Singapore, Penang, See also: Bengal, See also: Reunion, See also: Brazil, French See also: Guiana and the West Indies
.
The trees yield fruit in eight

years after sowing the seed, reach theirSee also: prime in twenty-five years, and bear for sixty years or longer
.
Almost the whole See also: surface of the Banda Islands is planted with nutmeg trees, which thrive under the shade of the lofty Canarium commune
.
In Bencoolen the tree bears all the See also: year round, but the chief harvest takes place in the later months of the year, and a smaller one in See also: April, May and See also: June
.
The ripe fruit is about 2 in. in diameter, of a
rounded See also: pear-shape, and when mature splits into two, exposing a See also: crimson arillus surrounding a single seed (See also: figs
.
I, 2)
.
When the fruit is collected the pericarp is first removed; then the arillus is carefully stripped off and dried, in which See also: state it forms the mace of commerce
.
The seed consists of a thin, hard testa or See also: shell, enclosing a wrinkled kernel, which, when dried, is the nutmeg
.
The kernel consists n m mainly of the abundant endosperm, which is See also: firm, whitish in colour and marbled with numerous reddish-brown vein-like partitions, into which the inner seed-coat penetrates, forming what is known botanically as ruminated endosperm
.
To prepare the nutmegs for use, the seed enclosing the kernel is dried at a gentle heat in a drying-See also: house over a smouldering fire for about two months, the seeds being turned every second or third See also: day
.
When thoroughly dried the shells are broken with a wooden mallet or flat See also: board and the nutmegs picked out and sorted, the smaller and inferior ones being reserved for the expression of the fixed oil which they contain, and which forms the so-called oil of mace
.
The dried nutmegs are then rubbed over with dry sifted lime.The See also: process of liming, which originated at the See also: time when the Dutch held a See also: monopoly of the See also: trade, was with the view of pre-venting the germination of the seeds, which were formerly immersed for three months in milk of lime for this purpose, and a preference is still manifested in some countries for nutmegs so prepared
.
It has, however, been shown that this treatment is by no means necessary, since exposure to the See also: sun for a week destroys the vitality of the kernel
.
Penang nutmegs are never limed . The entire fruit preserved in syrup is used as a sweetmeat in the DutchSee also: East Indies
.
" Oil of mace," or nutmeg butter, is a solid fatty substance of a reddish-brown colour, obtained by grinding the refuse nutmegs to a
See also: fine powder, enclosing it in bags and steaming it over large cauldrons for five or six See also: hours, and then compressing it while still warm between powerful wedges, the brownish fluid which flows out being after-wards allowed to solidify
.
Nutmegs yield about one-See also: fourth of their See also: weight of this substance
.
It is partly dissolved by cold See also: alcohol, the See also: remainder being soluble in See also: ether
.
The latter portion, about to% of • the. weight of the nutmegs, consists chiefly of myristin, which is a compound of myristic acid, C14H2802, with See also: glycerin
.
The fat which is soluble in alcohol appears to consist, according to See also: Schmidt and Roemer (See also: Arch
.
Pharnt
.
[31, xxi
.
34-48), of See also: free myristic and stearic acids; the brown colouring See also: matter has not been satisfactorily investigated
.
Nutmeg butter yields on See also: distillation with See also: water a volatile oil to the extent of about 6 %, consisting almost entirely of a See also: hydrocarbon called myristicene, C[01116, boiling at 165° C
.
It is accompanied by a small quantity of an oxygenated oil, myristicol, isomeric with carvol, but differing from it in not forming a crystalline compound with hydrosulphuric acid
.
Mace contains a similar volatile oil, macene, boiling at 16o° C., which is said by Cloez to differ from that of nutmegs in yielding a solid compound when treated with hydrochloric acid See also: gas
.
The name nutmeg is also applied to other fruits or seeds in different countries
.
The See also: Jamaica or calabash nutmeg is derived from Monodora Myristica, the Brazilian from Cryptocarya mosclaata, the Peruvian from Laurelia sempervirens, the See also: Madagascar or clove nutmeg from Agathophyllum aromaticum, and the Californian or stinking nutmeg from Torreya Myristica
.
The cotyledons of Nectandra Puchury were at one time offered in See also: England as nutmegs
