Thecollefting of his fecular compofitions into a folio vo- 

 lume in 1700, under the title of " Ampliion Anglicus," was 

 doiibtlefs occafioiied by the great fuccefs of the " Orpheus 

 BritLumicns," a fimiiar colleftiou of Purccll's dramatic and 

 mifce'bneous fong«, publirtied by his widow, in 169S. But 

 wliethcr Dr. Blow was Simulated to this publication by 

 emulation, envy, or the folicitation of his fcholars and 

 friends, by whom there are no lefs than fifteen encomiaftic 

 copies of verfes prefixed to tht; work, the ungrateful public 

 feems to have remained aluays infenfible to thefe ftrains of 

 the modern Amphion, which were not only incapable of 

 building cities, but even of fwpporting his own tottering 

 fame. 



Some of his innumerable deformities from the Amphion 

 Anjjiicus are added to thofo of his church mulic, in the 

 third vol. Gen. Hill. Muf. " Go perjured man," is the 

 bell of all his fecular prcduftions ; but that, which was 

 an imitation of a duet by Cariifimi, " D'lle, c'leli," is 

 overloaded, in his " Amphion Anglicus," with a laboured 

 and unmeaning accompaniment. P. 44 and 46 of this col- 

 kiflion, contain two of his bed ballads, " Sabina has a 

 tlioufand charms," and " Philander do not think of arms." 

 In thefe ballads the union of Scots melody with the Enghfli, 

 is firft confpicuous. The fubjeft of a fong, p. 16S, " Ori- 

 *hea's bright eyes," is llkewiie broad Scots.

 ftrument for the purpofe of increalu.^ the heat of a candle 

 or lamp, ,n the fame manner as a pair oi bellows is employed 

 tor railing the temperature of a common fir^ or furnace It 

 IS not known at what time or by whom tlm very ufeful 

 tnitrument was invented, but it appears to have been employed 

 by glafs-workers, enamellers, and jewellers, long beWi it 

 was adopted as an article of chemical apparatus. The firlV 

 intimation of its value to the chemill is to be found in 

 Kunkel's treatife on glafs-makincr. 



The common glafs-blower's lamp is reprefented in P/aleX. 

 A- ^■{Chenaflry). A, 'u a wooden table, within the frame 

 ot which IS fixed a pair of double bellows B, that are worked 

 by the fo(;t cf the artilt; from the nozlc of the bellows 

 proceeds a pipe of lead, or tinned iron, CC, which, fiiil rifing 

 perpendicularly, is then brought under the top of the table 

 to n, where it penetrates the wood, and terminates onits upper 

 fiuface, m a recurved hollow cone E, the apex of which is 

 pierced with a minute round hole. A flioe-lamp, F, is 

 placed on the table, fo that its wicii is fomewhat below, and 

 about half an inch dillant from the aperture of the pipe ; the 

 bellows b-ing then worked, a c-nllant llream of airis thrown 

 upon the wiek of the lamp, producing a long conical hori- 

 zontal flame, G, of very confideiablc intenfity. The increafed 

 heat of the flame a;)pears to depend, in part, on a more rapid 

 and complete combullion of the oil, and in part, alfo, on the 

 concentration of the flame, by the adlon of the blall. The 

 flame, upon examination, will'he found to coufift of an exte- 

 rior yellow cone, inclufing another of a lighter yellow colour, 

 at the extremity of which laft is the focus of grcatell heat. 



B L O 



The Ihoc-lamp (more diftiiidly reprefented injg. 2.) is fo 

 called from its refemblaiice to a flioe. It is niade of tinned 

 iron, and confiils of two parts ; the exterior, a, ferves to hold 

 the proper lamp, and to retain the oil, which cccafionally 

 drops from the wick ; the lamp, b, has a fixed cover, except 

 at the tip, c, where a circular aperture is left for the wiek, 

 d, which confiils of a bundle of cotton threads, about an inch 

 in diameter ; at <? is a hinge, by which that part of the lid 

 neareit the wick may be laifed, in order to pour in frcfli oil, 

 or to renew or raife the wick. 



The glafs-worker's blow-pipe is, however, not fufGciently 

 portable for the ufe of the chemill and mineralogill, and it 

 was a happy thought of Swab, the Swedilh mineralogift, to 

 fubftitute the lungs for the btUows. Gahn, Engeliroem, 

 and Bergman fuggefted various improvements in the con- 

 ftruftion of this inftrument, which now appears to have 

 attained as great a degree of perfection, as it is perhaps 

 capable of. 



The common chemical blow-pipe copfiils of five parts ; 

 {C/:tmi/Iry, Plate YA. Ji^. T,.) the moutli-piece, a; a plain 

 tube, /; ; a bulb, r ; a curved tube, (// and a nut, e 



The mouth-piece (more dilUnClly reprefented by /^. 5.) 

 is made of ivory, the re!l of the apparatus being ot brhis, and 

 fi s clofcly into the pipe, b, fo as to be air-tight ; the bulb, 

 t, is divided into two hemifpheres, which fercvv into each 

 other, and is defigned to coiletl and condmfe the moiltiire of 

 the breath ; into the lower hcmifphere is (Ixed the recurved 

 tube, d (as reprefented \n Jig. 4.), in fuch a manner as to 

 prevent the coiidenfcd vapour from efeaping out of the bulb; 

 the nut, e, is a hollow cylinder fuPhcieiitly wide at one end 

 to receive the extremity of the curved tube, and peifortcd 

 at the other with a fmall round hole, to ahow a paiTage f#r 

 the air; each blow-pipe has generally three of thefe nuts 

 (Jig. 6.), with apertures of difTerent fixes, the largell of which 

 does not exceed the diameter of the fmallcfl; pin. 



In ufing the portable blow-pipe, the only difficulty is to 

 keep up a conllant llream of air ; which is to be done by 

 performing the fundlion of refpiration through the nollri's 

 alone, diverting fiom time to time a portion of the explrai'ion 

 into the mouth for the fupply of the blow-pipe, and lorcing 

 it through the tube by the action of the inulelesof the cheek. 

 This knack is by fome acquired in an inftant, while others 

 are a long time in making themfelves mailers of it. To thofe 

 who experience any difficulty in the free ufe of this inftru- 

 ment, the following direftions may be of fervice. Firll, let 

 the learr.cr accuflom himltlf to breathe freely with the mouth 

 mut ', then in making an expiration, let him transfer the air 

 intp the mouth, till the cheeks aie moderately inflated, and rc- 

 taming it there, let him difchargc the furplus of theexpirntiou 

 through the nollrils, and then make two or three eafy infpira- 

 tionsandexpiratior.stl'.rough the noftrils, without allowing the 

 air in the mouth to cfcape. When praftice has rendered this 

 eafy, which may becfFcded in half an hour, let the nut v>ith 

 the fmalleft aperture be fixed on the curved tube of the blow- 

 pipe, and introduce the mouth-piece within the lips ; then in- 

 flate the cheeks by an expiration, and continue breathing 

 eafily through the nollrils, till nearly ll'.e whole of the air has 

 pafltd out of the mouth through the tube ; then renew the 

 air as before, and, after a few days' prattict, the mufeks of 

 the mouth will be accuftomed to this new mode of exertion, 

 and an uniform uninterrupted ftream of air may be kept up for 

 half an hour without any extraordinary fatigue. A v. ax can- 

 die,/, having burnt long enough to allow the wiek to be 

 turned down, in the manner reprefented in the plate, the nut 

 of the blow-pipe is to be applied to the arch of the wick, and 

 the air, as it comes through, will bend the flame into a neat 

 horizontal cone, the exterior part of which is yellow, and the 



interior
