produce a few bunches on each plant. This metliod is now 

 praAifed in many cafes, and found to be very eafy and 

 convenient. 



The fecond fpecies requires artificial heat in this climate, 

 and may be increafed from feeds, obtained from abroad, 

 which fhould be fowii in fmall pots, and be plunged into a 

 hot-bed of tanner's-bark. When the plants come up and 

 are fit to remove, they fhould be each planted out into a 

 feparate fmall pot filled with light earth, and plunged into a 

 frelh hot-bed, (hading them from the fun till they have taken 

 new root ; when they muft be treated in the fame way as 

 other tender exotic plants, always continuing them in the 

 ftovc, otherwil'e they will not fucceed well. 



The third {hould be planted againft a wall, and treated in 

 the fame way as the common vine, being raifed by cuttings 

 or layers in the fame manner. 



The fourth fort is preferved in fome gardens for variety ; 

 but it rarely produces flowers in this climate, and has not 

 much beauty. It is increaftd by laying down the young 

 branches in the fpring, which moftly put out roots in one 

 year fit to remove, when they may be taken off and planted 

 out where they are to remain. Thefe require fupport ; and 

 as their young branches are tender, and liable to be kiUed 

 by froft, they fhould be planted againft a wall, or pale, ex- 

 pofed to the fouth. Tlie young (lioots fhould be fhortened 

 down to two or three buds in the fpring, which will caufe 

 the /hoots of the following fummer to be much llronger.

VITRIACO, Philippus de, in Biography, is men- 

 tioned with great encomiums by early writers on counter- 

 point. We found a traft of his writing in the Vatican 

 library, N° 5321, of which we obtained a copy. He ii 

 the reputed inventor of the minim, and a compofer of 

 motets, which have been very much celebrated by old 

 mufical writers. His name very frequently occurs in an- 

 cient authors, particularly in England, v here he has been 

 commended both in verfe and prof;. " William Cornifh, 

 chapelman to the moft famofe and noble kynge Henry VII., 

 in a parable between Trouth and Informacion, publiflied in 

 Skelton's works, i2mo. 1736, names him among the 

 greateft muficians upon record. 



" And the firfl principal, whofe name was Tuballe, 

 Guido, Boice, John de Muris, Vitryaco, and them al." 



An anonymous Latin writer in the Cotton mufical manu- 

 fcript (Brit. Muf. ) fays he invented the minim, and was 

 a mufician univerfally approved and celebrated in his time. 

 The author of the manufcript in the Bodleian hbrary, attri- 

 buted to Thomas of Tewkefbury, fays the fame. Morley, 

 Ravenfcroft, and Butler, are of this opinion ; and Morley 

 tells us, that he ufed red notes in his motets to imply a 

 change of mode, time, and prolation. Vitriaco, however, 

 makes no mention of fuch in his traft on counterpoint ; and 

 his motets, if they could now be found, fuch is the tran- 

 fient Hale of mufic, would be utterly uninteUigible ; though 

 Morley tells us, that " they were for fome time of all others 

 befl etieemed and moft ufed in the church." See Motet.

VITRIFICATION, or Vitrifaction, the aft of 

 converting a body into glafs, by means of fire. 



Of all bodies, fand, flints, and pebbles, with alkali.ne

 glafs is principally made. See Glass. 



Gold held, by M. Homberg, near the focus of the duke

 than gold. Memoirs of the Royal Academy, 1702.
