1. G. maranllna. Linn Mant. 2. 170 Sm. Exot. Bot. 

 V. 2 85 t. 103 (Colebrookia bulbifera; Donn Cant. 1.) — 

 Appendage of the lil.iment four-Iobed, divaricated, terminal. 

 Spike not taller than the leaves. Braclcas elliptical, broad, 

 longer than the calyx — Native of Bengal, from whence it 

 was fent by Dr. Roxburgli to the late lady Amelia Hume 

 in 1800. It flowers in the ftove in July and Auguft. Root 

 perennial, tuberous. Stems feveral, herbaceous, about two 

 feet higli, fimple, leafy. Leaves elliptical, acute, entire, 

 with one rib and numerous parallel firaple veins; fniooth 

 above; foft and finely downy beneath ; their fcotilalks long, 

 (lieathing, bearded at the top, which is extended upwards 

 into a pair of rounded auricles. Spike terminal, folitar)-, fim- 

 ple, creel, more or lefs lax, about as tall as the leaves, or 

 rather under that height. Bracleas alternate, fefiile, elliptical, 

 broad, concave, many-ribbed, fomewhat downy, minutely 

 dotted; the lower ones each bearing one ovate bulb; tiie 

 upper ones a clufter of {•tsexA f.o'-juers, each of wiiich is 

 accompanied by its own f.'.ialler braclea. TXvti'i Jhiucrs are 

 very traniient, (lender, orange-coloured, witii a deeper Ipot 

 in the centre of the lip.

 ment arrcw-fhaped, narrower than tlie anljier. Cluiler elon- 

 gated, cylindrical. Bracleas fliorter than the calyx, deci- 

 duous. — Gathered by Dr. F. Buchanan in the woods of 

 Upper Nepal, flowering in .lune. Habit of the lull, but 

 talLr, with larger more pointed leaves. The tnflorcjeaiee is 

 much more linking, and confifts of a long terminal rncemus 

 of numerous orange-coloured Jloirers, which are twice the 

 fize of the former, ar.d eiTentially diflinguifhed from that by 

 the arrow-fhaped form of tlie appendage to their filament, 

 which does not extend beyond the anther, c-ccept at its 

 rounded termination.

 (Hura .Siamer.fium ; Koenig in Retz. Obi. fafc. 3. 49 ) — 

 Appendage of the filament four-lobed, divaricated. Chiller 

 fomewliat corymbofe. Bratieas fhorter than the calyx. Lip 

 towards the middle of the filament — Found by Koenig plen- 

 tifullv in graiTy (hady parts of the ifiand called Young Cey- 

 lon, in the Eaii Indies. The ehifler of flowers is fhorter and 

 more corymbofe tl-.an in G. racemofa, and the corolla is vane- 

 gated with orange, white, and different fliades of violet. 

 The appendage of the filamient nearly refembles that of G. 

 niarantina, but the fituation of the lip, thrull, as it were, 

 half way up the filament, above the other lobes of the corolla, 

 is altogether peculiar. For this, however, we depend on a 

 drawing made by Mr. Sidney Parkinfon, and communicated 

 by fir Jofeph Banks, of the accuracy of which we have no 

 reafon to doubt. Kcenig mentions a more dwarf variety, 

 found near the town of Malacca. Cm this be what has 

 lately been introduced into the ttoves about London by Dr. 

 Roxburgh, and which we have feen and exair.ined at fir 

 Abraham Hume's, and at Mefirs. Lee and Kennedy's, flow- 

 ering in June 1810L It is figured in Curtis's Magazine,

t. 1320, where Dr. Sims has, we think, juftlv made thii 

 pretty plant a new genus, by the name of Man'lf a fallal -.ria. 

 It differs from Globba in having a radical, not tenninal, in- 

 florefcence, which, as far as wc know, is an infallible indi- 

 cation of a generic difference in this natural order, and there- 

 fore the flower affords, as was neceffarily to be expected 

 clear effential characters of diltinftion, in tlie two Ion"- 

 linear appendages to the lower part of the filament, which 

 fupply the place of two of the inner fegments of the cjrolla, 

 while the lip, which makes the third, is not bifid at its 

 upper extremity. The large purple brafiecs, and the branch- 

 eA fl'/ivcr-JIalk, are alfo remarkable. S. 



GLOBE, in Geometry, a round or fphcrical body, morf 

 uf.ially called 7s,fphere; v.hicli fee. 



The earth and water together arc fuppofed to form a 

 globe; hence called the terraqueous globe. 



The planets, both primary and fecondai y, are fuppofcd, 

 as well as our earth, to be folid globes. 



The earth is, in a particular fenfe, called the globe, or 

 globe of earth ; though it is now well known that this is 

 not its true figure. Sec Figure of the Earth. 



Globe, Refjlance of a. Sec Resist.wci;. 



Globe is more particularly nfed for an artificial fplicre of 

 metal, plafter, paper, or fome other matter; on whofe 

 convex furfacc is drawn a map, or reprefentation, either of 

 the earth or heavens, with the feveral circles conceived 

 tiiereon. 



Globes are of two kinds, terrejlrinl and cehfih! : each of 

 very confiderablc ufe, the one in ailronomy, aad the other 

 in geography, to perform many of the operations thereof in 

 an ea.fy, fer.fible manner, fo as to be conceived without any 

 knowledge of the mathematical grounds of thofe arts. 



Th.e fundameiital parts, comni<m to both globes, are an 

 axis, reprefenting that of the world, and a fphcrical fhell or 

 cover, which makes the body of the globe, on whofe exter- 

 nal furface the reprefentation is drawn. 



Globes, we have obfervcd, are made of divers materials, 

 I'iz. filver, brafs, paper, plafter, &c. Thofe commonly 

 ufed are of plafter and paper; the conftruclion whereof is 

 as follows. 



Globes, Conflru^kn of. A wooden axis is provided, 

 fomewhat lefs than the intended diameter of the globe ; and 

 into the extremes hereof two ir»n wires are driven for poles: 

 this axis is to be the beam or bafis of the whole itrudlurc. 



On the axis are applied two fpherica', or rather hemi-fplie- 

 rical caps, formed on a ki;;d of wooden mould or block. 

 Thefe caps confift or pallcboard and paper, laid, one lay 

 after another, on the mould, to the llucknefs of a crown 

 piece- ; after which, having ilood to dry and embody, mak- 

 ing an inciilon along the middle, the two caps, thus parted, 

 ai"e flipped off the mould. 



They remain now to 1ie applied on the poles of the axis, 

 as before they were on thofe of the mould ; and to fix them 

 in their new place, the two edges are fown together «ith 

 packthread, &c. 



The rudiments of the globe thus laid, they proceed to 

 ftrengthen and make it fmooth .and regular. In order to 

 this, the two poles aiv halped in a me!;.lli:ie femi-circlc of 

 the fize intended; and a kind of plafter, made of whiting, 

 water, and glue, heated, melted, and incorporated trgc- 

 ther, is daubed ;J1 over the paper furface. In proportion as 

 the plafter is applied, the ball is t:irned rcund in tlie fenv- 

 circle, the edge whereof pares off whatever is fupcrfluoiis, 

 and beyond the due dimenfion, leaving the rcll adhering iu 

 places that are ftiort of it. 



After fuch application of plafter, tke ball (lands to dr)- ; 

 wliich done, it is put again in the femi-eircle, artd frrfti
