S20 MISCELLANEOUS. 



bottle with lime. Fix an iron vessel, as a shovel, 

 for instance, with common sand, and put it over 

 the fire. Set the phial in this sand, having loosely 

 stopped it with a cork. Stir about the ingredients 

 with a wire, and mix them together ; taking care 

 that the phosphorus does not catch fire by too 

 great an access of air. Keep the bottle in the 

 sand till the phosphorus is thoroughly incorpor- 

 ated with the lime, when it will be of a reddish 

 yellow. 



This bottle is extremely convenient for pro-

 this purpose, nothing more is necessary than to 

 uncork the bottle, and to introduce a brimstone 

 match, stirring it about a little, by which it will 

 catch fire and light. 



The bottle must be always kept carefully cork- 

 ed, and opened as seldom as possible. 



A more durable kind may be made by uniting 

 together one part of sulphur with eight of phos- 

 phorus. When this is used, a match is introduced 

 into it, and then rubbed upon a bit of cork. 



To make Phosphuret of Lime. 



Put half an ounce of phosphorus, cut into 

 small bits, into a glass tube about a foot long, 

 and half an inch in diameter, closed at one end. 

 Fill up with quick-lime grossly powdered, and 

 stop the mouth of the tube loosely. Heat that 

 part of the tube which contains the lime over a 

 chafing-dish, till it be red hot; and then apply 

 the heat of a lamp to the part containing the 

 phosphorus, which will sublime, and mix with the
