— Petals fpreading, (lightly concave. Neftaries hardly io 

 long as the ftamens. — Native of Pennfylvania, flowering 

 in May. Specimen| and feeds were fent us in 1793, by the 

 late Rev. Dr. Muhlenberg, under the above name, by 

 which he has publifhed the plant in his Catalogus Plantarum 

 America SeptentrwnaUs. This name is fo iingularly apt, one 

 fpecies of this genus being appropriated, as it appears, to 

 each of three quarters of the world, that, though we by no 

 means approve of fpecific names taken from particular 

 countries, on a limited fcale, we cannot rejeft this : itill lefs 

 can we aflent to an arbitrary change of the other two. On 

 this fubjeft we have the univerfal fufFrage of botaniils in 

 our favour. The fpecies before us is fmaller than either of 

 the other two, and feems to have fcarcely more than five 

 petals, which are obovate, and of a yellow, not orange, 

 colour. Their fpreading pofition fufficiently diftinguiiheS 

 the plant from T. europaus, as the fhortnefs of the neSaries 

 does from aftaticus. The capfules are fhort and abrupt, 

 crowned by the rather elongated^j'/fj. 



Mr. Donn mentions two other American fpecies, by the 

 names of intermedius and hybrldus, which we prefume to 

 be varieties of amerkanus. We have obferved a difference 

 of appearance, with refpeft to fize and colour, in plants 

 raifed from our original parcel of feeds, and Dr. Muh- 

 lenberg makes but one American fpecies. The date of 

 the introduftion of T. amerlcanus ought to be 1794, not 

 1805. 



T. patulus, Salif. Tr. of Linn. Soc. v. 8. 303 ; Helle- 

 borus ranuncuUnus, Sm. Plant. Ic. t. 37, is moft evidently 

 no irol/ius, on account of its tubular neftaries. 



Trollius, in Gardening, comprifes fome hardy, her- 

 baceous, flowery, perennial plants, as the globe ranunculus, 

 or globe-flower, among which the fpecies cultivated are the 

 European globe-flower (T. europius) ; and the Afiatic 

 globe-flower (T. afiaticus). 



Thefe two plants are of a rather tall hardy growth, 

 affording confiderable ornamental effeft in their large flowers, 

 which grow in the firft fort in a particular converging 

 manner, or turn in an inward direftion, or fomewhat revolute 

 mode, fo as to give them a perfeft globular form, from 

 ■which they derive the name of globe-flower. They appear 

 in both forts in the beginning of fummer. Thofe in the 

 Afiatic or latter kind, however, are not connivent, but 

 fpread out and fliew fome of the inner parts, which are of a 

 fine fafFron-colour, and difplay a ftriking elegant Angularity 

 in their appearance, vrhich renders them highly valuable for 

 their ufe in the flower-garden. They are both defirable 

 flower-plants. 



Method of Culture. — The means of propagation and in- 

 creafe in thefe plants are occafionally by fowing the frefli 

 feeds of them, and the parting of their roots. 



In the former method, the feeds (hould be fown in (hallow 

 drills, in a fomewhat (hady border or other place, in the 

 autumnal or fpring feafons, covering them in to the depth 

 of nearly half an inch, when they readily grow and produce 

 plants for fetting out in other parts. 



In the latter mode, the roots (hould be taken up in the 

 autumnal feafon, when the leaves decay and fall off, or very 

 early in the fpring months, and be divided into feveral parts, 

 but not by any means into too fmall flips, and then be 

 planted out either where they are to remain, or in nurfery 

 rows, where they are to continue for twelve months, when 

 they will be ready to fet out finally. 



The feedhng plants (hould be fet out in fummer, or to- 

 wards the autumnal fealon, in rows about fix inches afunder, 

 where they are to continue about fix or eight weeks, to become 



T R O 



perfeftly ftrong, and be finally planted out in the places 

 where they are to remain. 



And the root -plants, which are fet out in rows, may be 

 removed in the auiumn or fpring feafons to the fpots where 

 they are finally to grow and continue. 



As thefe plants are natives of moift and (hady fituations, 

 they are generally the moft fuccefsfully planted in places 

 where the circumllances are the fame in this chmate, though 

 they will commonly grow very well in any border or com- 

 partment of the garden which is not over dry, or without 

 moifture. 



Thefe plants multiply extremely faft; by the roots, and 

 are of a great many years duration. 



They are highly deferving of a fituation in all curious 

 coUeftions in the flower-gardens and pleafure-grounds, where 

 they have a fi-ie eflFeft in the clumps, borders, and other 

 compartments. 



TROMBA, in G:ography, a fmall ifland near the coaft 

 of Iftria. N. lat. 45° 3'. E. long. 13° ^i'. 



Tromba, in the Italian Mufic, either denotes the common 

 trumpet, the buccina of the ancients, or the modern facbut, 

 but more properly our triunpet. 



TROMBETAS, in Geography, a river of Brafil, which 

 runs into the river of the Amazons at Pauxis. 



TROMBETTA, in Ichthyology, a name given by the 

 Italians to the filh commonly called fcopolax by authors.

Trombetta, in the Italian Mufic, a fmall trumpet, being 

 the diminutive of tromba. 



TROMBONE, a wind-inft;rument blown by the mouth, 

 and refembhng in form the military trumpet, of which it is 

 the bafe, the name implying the great trumpet. It differs, 

 however, from the trumpet in being divided into two 

 branches or parts fitted to fockets, giving the performer 

 power to lengthen and (horten the general tube at his plea- 

 fure, according to the different tones which he vrifhes to 

 produce. On which account it is called in Latin, tuba duc- 

 tilii. The Germans call it paufaune, and the French fac- 

 queboute. 



Zarlini has defcribed this inftrument under the title of 

 trombone amovibile, and the quantity and quality of the founds 

 it is capable of producing, very exaftly. 



" The trombone," fays he, Supplimenti Muficali, lib. iii. 

 cap. 5. "is an inftrument truly worthy of confideration, 

 which I have feen and often heard by good performers, be- 

 ginning at the loweft found which it is capable of producing ; 

 when, being clofed in all the joints, it can produce no found 

 lefs than the oftave ; then from the oftave to the 5th ; nor 

 from that can it produce a lefs interval than the 4th ; and 

 from the 4th to the 3d major, then the 3d minor, after 

 which another 4th, the key-note, from which it can form a 

 complete feries of eight notes. No other founds than thefe 

 can be produced without altering, moving, and lengthening 

 the inftrument." 



P^re Merfenne, in his experiments on this inftrument, 

 (Harmon. Inftrum. lib. ii.) found it capable, by lengthen- 

 ing or (hortening the lower part of the inftrument, of form- 

 ing a regular feries of fifteen founds, from double C in the 

 bafe, to C on the fixth hne. 



The inftrument is made of brafs, of which there are five 

 forts : canto, alto, tenor, bafe, and double-bafe. It is 

 much ufed in the large churches of Germany. They can 

 produce all the tones and femitones in gradation. The 

 manner of writing for them is the fame as for difTerent 

 voices, and on the fame ftaff of five lines.
