TROP./EOLUM, in the Linnsean fyftem of botany, the name of a genus of plants, called by Tournefort cardamindum, and by C. Bauhine najiurtium ihduum.
The characters are thefe : The cup is a deciduous perian- thium, compofed of a fingle leaf, divided into five fegments, erecto- patulous, acute, coloured, and the two lower ones narrower than the reft. The flower confifts of five round ifh petals, inferted into the divifions of the cup ; the two up- per petals are feflile; the fhree others have very long and barbated ungues. The ftnmina are eight fhort, fubulated, declinated, unequal filaments. The antherfe are erect, Ob- long, quadrilocular, and afiurgent. The germen is round- ifh, ftriated, and formed of three lobes. The ftyle is fim- ple, erect, and of the length of the ftamina. The ftigma is trifid and acute. The fruit confifts of three capfules, con- vex, falcated, and ftriated on one fide, and angular on the other. The feeds are three in number, gibbous on one fide, and angulated on the other; but, upon the whole, fomewhat roundifh, and ftriated deeply. Vid, L'xnn&i Gen. Plant, p. 158.

TRUG (Cjr/.)— Trug is alfo a country word for a milk- tray, or a hod to carry mortar in.
TRUMPET (Cycl.)— The uuial founds of the trumpet are reprefented by the following mufical notes.
I.2.3.4. 5.6. 7. 8.9.10.11.12.13.14. 15.16. . J,vC
Here the loweft found being denoted by 1, the pitch of the reft, or the number of their refpective vibrations, dur- ing the time that C vibrates once, will be exprefled by the numbers denoting the order of the founds, 2, 3, 4, 5, &c. The founds exprefled by the mufical numbers, that is, by 2, 3, 5 *, and their compofites, which are 4, 6, 8, 9, 10, 12, is, 16, are all perfectly in tune; but the founds ex- prefled by numbers not mufical, as 7, it, 13, 14, are falfe. Three of thefe, viz. B^, its octave, and A, diftinguifhed by/ placed over them, are too flat; and the remaining note F, marked with an S, is too fharp. — [* See Musical num- bers, Suppl. and 'Jppend.']
The reafon of which is, that B b ought to be a tone major "below C ; that is, its pitch to that of C will be as 8 to 9 ; But the proportion given by the trumpet is as 7 to 8 ; which feeing a lefs proportion than that of 8 to 9, it follows, that B h will be too flat. The fame holds true of its octave. And A being a tone minor above G, it ought t6 be to G as 10 to 9 : but in the trumpet, it is to G as 13 to 12 ; which being lefs than the proportion of 10 to 9, it follows, that A will be too flat. On the other hand, F ought to be a femitone major above E ; that is, F ought to be to E, as J.6 to 1 5 : but, in the trumpet, F is to E, as 1 1 to 10 ; which being a greater proportion than that of 16 to 15, it follows that F is too high or too fharp.
This fyftem of trumpet notes is an effectual confutation of thofe who are for introducing 7, rr, 13, and other primes into mufic. "

Turcois colour, the pale blue of the natural turcois gem. This is a very favourite colour in the glafs trade, and is given to glafs in the following manner. Firft calcine com- mon fea-falt, and beat it to a fine powder; then make a pot of the fea-green glafs, of a fair and full colour: to this, when in fufion, throw in at times the powder of fait, till the mafs has loft all its tranfparence, and is become paler and opake; then add, by very fmall quantities at a time, more and more fait, till the colour is exactly that of the torcois gem ; and when it is fo work it immediately, for the fait is foon burnt off, and the glafs becomes tranfparent, and of its green colour. If it become tranfparent while working, more fait muft be thrown in, and that will reduce it to the fame opacity again. Neri'.s Art of Glafs, p. 57.
Turcois enamel, an enamel exactly of the colour of the tor- r«V gem, and very much refembling it in many refpects.
