Experiments of Candle Wicks, t$-c. V27 



its not being liable to gutter. How far these advantages may 

 avail to render it deserving of being used as a preferable 

 substitute for Tallow, I will not pretend at present to say ; 

 but if, as I am inclined to expect, the Chloride of Lime is 

 found fitted for the purpose, I think it probable that it may be 

 found to deserve a preference in many cases. 



I may mention that the manner in which the Candles with 

 two wicks were made, was as follows : I got a straight tube of 

 tin, to one end of which I fitted a stopper of wood, having two 

 holes at the proper distance apart. Through one of these 

 holes I passed the end of the Wick from without, inwards, 

 and carried it through the other hole from within, outwards, 

 fastening this end on the outside with a pin which fitted the 

 hole. I then passed a wire, having a hook at the end, through 

 the tube, laid hold of the Wick, and drew it to the other end, 

 where I fastened it with a piece of wood of such thickness as 

 to keep the Wicks at the proper distance from each other, and 

 fastened the other extremity of the Wick with another pin 

 passed through the stopper. It is now ready for the reception 

 of the melted matter, which is poured in in the usual Avay. 

 This arrangement has 4his advantage, that the Candle may be 

 drawn out sooner than it can be done in the usual way, in 

 which if any considerable force is used, the Wick is liable to 

 break, an inconvenience which is avoided by pushing in the 

 stopper, after having taken out the pins, the Candle being 

 thus forced upwards is loosened from its fastenings, and may 

 then be more readily withdrawn entirely- 



I am indebted for the following Botanical account of the 

 Candleberry Myrtle, to the kindness of Mr. Bowie.
