Dr. Kitclseiitr says that ^11 the water necessai'j should be 

 poured ia at firdt, as he considers the second diawiug bad, and 

 jrecommends the use of two (ea pots rather than two drawings. 

 X)r. Trusler's method was to make a strong infusion by placing 

 boiling hot water upon the tea, and allow it to stand twenty 

 minutes, putting into eacli cup no more than is necessary to jSll 

 it one-third full ; then each cup was filled with hot water from 

 an urn ; thus the tea will always be hot, and eacli cup will be of 

 equal strength ; by this mode, one teaspoonful is considered 

 enough for three ordinary cups for each person. Dabuisson's 

 method was to put tea leaves into a kettle with cold water, cover 

 it tight, set it on the fire, and make it almost, but not quite boil j 

 then take it from the fire : when the leaves sink, it is ready for 

 tise. Doctors always differ. 



About forty years ago there was a learned contest among 

 scientific men, respecting the best substance for tea pots to be 

 made of, to draw the tea best ; metal was supposed by some to 

 he tlie most suitable, as tliey imagined it would prevent, in a 

 greater degree than any other substance, the escape of heat; 

 others supposed earthenware vras a worse conductor than metal, 

 and would prevent in a greater degree tlie escape of heat. Each 

 substance had its advocates ; they generally decided for one, 

 while experience favored the other. 



About this time Professor Leslie; of Edinburgh, found that, 

 although all heated substances throw ofi" invisible rays of radiant 

 heat, yet that the quantity projected depended m.uch more upon 

 the smoothness or roughness of the surface, tiian upon the con- 

 ducting power of the body ; and t'lat polished metal, although 

 one of the best conductors of heat, v/as one of the worst r.idiators, 

 metal not polished being a good radiator as v^'eli as conductor. 

 Since the date of which discovery, bright metal tea pots have 

 been considered to be most eil'ectual in preserving th.. heat of 

 the water j consequently bctli tlieory and practice now agre-e as 

 to the substance best adapted for tea pots."
