764. lampe; so in the MSS. It is clearly put for lambe, a corruption of O. Fr. lame, Lat. lamina. Were there any MS. authority, it would be better to read lame at once. Cotgrave has—'Lame; f. a thin plate of any metall; also, a blade.' &c. Nares has—'Lamm, s. a plate, from Lat. lamina. "But he strake Phalantus just upon the gorget, so as he batred the lamms thereof, and make his head almost touch the back of his horse"; Pembr. Arcadia, lib. iii. p. 269.' Lame in old French also means, the flat slab covering a tomb; see Godefroy. So here, after the ingredients have all been placed in a pot, they are covered over with a plate of glass laid flat upon the top.
It is strange that no editor has made any attempt to explain this word. It obviously does not mean lamp! For the insertion of the p, cf. solempne for solemne, and nempne for nemne; also flambe for flame; see the Glossary.
766. enluting. To enlute is to close with lute. Webster has—'Lute, n. (Lat. lutum, mud, clay). A composition of clay or other tenacious substance, used for stopping the juncture of vessels so closely as to prevent the escape or entrance of air, or to protect them when exposed to heat.'
The process is minutely described in a MS. by Sir George Erskine, of Innertiel (temp. James I.), printed by Mr. J. Small in the Proceedings of the Society of Antiquaries of Scotland, vol. xi. 1874-75, p. 193, as follows:—'Thairfoir when all the matter which must be in, is gathered together into the pot, tak a good lute maid of potters clay, and mix it with bolus and rust of iron tempered with whitts of eggs and chopt hair, and mingle and worke thame weill togither, and lute ȝoure pott ane inch thick thairwith, and mak a stopple of potters earth weill brunt, to shut close in the hole that is in the top of the cover of the pott, and lute the pott and the cover very close togither, so as no ayre may brek furth, and when any craks cum into it, in the drying of the lute, dawbe them up againe; and when the lute is perfectly drie in the sunne, then take a course linen or canvas, and soke it weill in the whitts of eggs mixt with iron rust, and spred this cloth round about the luting, and then wet it weill again with whitts of eggs and upon the luting'; &c.
768. The alchemists were naturally very careful about the heat of the fire. So in The Alchemist, ii. 1:—
'Look well to the register,
And let your heat still lessen by degrees.'
And again, in iii. 2:—
'We must now increase
