luminous, and exhibits a very exact resemblance 

 of the planet. 



To make Phosphoric Oil. 



Put one part of phosphorus into six of olive-oil, 

 and digest them over a sand heat. The phosphorus 

 will dissolve. It must be kept well corked. 



This oil has the property of being very luminous 

 in the dark, and yet it has not sufficient heat to 

 burn any thing. If rubbed on the face and hands, 

 taking care to shut the eyes, the appearance is 

 most hideously frightful ; all the parts with which 

 it has been rubbed appear to be covered with a 

 very luminous lambent flame of a bluish colour, 

 and the mouth and eyes appear in it as black spots. 

 There is no danger attending this experiment. 

 The light of it is sufficient to show the hour of the 

 night on a watch, by holding it close to the bottle 

 when it is unstopped. 



To make Phosphorated Lime. 



Put a few grains of phosphorus into the bottom 

 of a Florence flask, and fill it up with quick-lime. 

 Place it over a lamp till the phosphorus has sub- 

 limed, and is thoroughly mixed with the lime. If 

 any of this lime be thrown out in the dark, it has 

 the appearance of a shower of fire, but cannot burn 

 any thing, as the quantity of phosphorus is too 

 small to produce any sensible heat. 



To make a Phosphoric Fire Bottle* 



Take a very small phial, and piit^into it a bit 

 of phosphorus as large as a pea, and fill up the
