LITHODIALYSIS 



consisting of a gauze charged with a solution of cor- 

 rosive sublimate in the serum of borses' blood. This 

 was found difficult to manufacture and was harsh and 

 non absorbent. The Fourth Method consisted in a 

 combination ofchlorid oi ammonium and bichlorid of 

 mercury, called Sal-alembroth. This was likev 



liable because of it- ready solubility in the 

 blood-serum. Fifth Method, a gauze containing 

 three or four per cent, by weight of the biniodid of 

 mercury. This proved irritating to the skin. A Sixth 

 Method consists in the employment o im- 



pregnated with a solution of a double cyanid of 

 zinc and mercur I with rosanilin. This is said 



to be non-volatile, unirritating, insoluble in water, 

 ami onlj soluble in 300 >.i blood-serum. It 



possesses but little germicidal power, while but I : 1200 

 keeps animal Quids free from putrefaction. Seventh 

 Method; lately Lister has returned to the use of 

 carbolic acid, preferring it to corrosive sublimate: (1) 

 because it is a more powerful antiseptic; (2) because 

 it has greater penetrating power. He combines it 

 with the use of the double cyanid gauze, preparing 

 the latter with a I to 20 solution of carbolic arid. 



Listerine [lis'-ter-in) [after Lister, an English physi- 

 cian]. A proprietary preparation said to contain 

 thyme, eucalyptus, baptisia, gaultheria, and mentha

Listing's Law. See Law. L.'s Reduced Eye, in 

 optics, a schematic simplified eye in which there is 

 a mean nodal or principal point lying between the 

 two nodal or principal {joints, the distance between 

 these two points being so small (only 0.4 mm.) that 

 the}- may practically be assumed to be one. By this 

 arrangement there is gained but one refractive surface 

 for all the media of the eye. See Eye.

 it- high saturating power makes its salts more highly
