LITHODIALYSIS 



isting of a gauze charged with a solution of cor- 

 ve sublimate in the serum of horses' blood. This 

 found difficult to manufacture and was harsh and 

 -absorbent. The Fourth Method consisted in a 

 mbi nation of chlorid of ammonium and bichlorid of 

 mercury, called Sal-alembroth. This was likewise 

 objectionable because of its 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 of gauze im- 

 pregnated with a solution of a double cyanid of 

 zinc and mercury colored with rosanilin. This is said 

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

 and only soluble in 3000 parts of blood-serum. It 

 possesse.- but little germicidal power, while but 1 : 1200 

 keeps animal fluids free from putrefaction. Seventh 

 Method ; lately Lister has returned to the use of 

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

 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 1 to 20 solution of carbolic acid. 



Listerine (liY-ter-in) [after Lister, an English physi- 

 cian]. A proprietary preparation said to contain 

 thyme, eucalyptus, baptisia, gaultheria, and mentha 

 arvensis, with two grains of benzo-boric acid in each 

 dram 



Listerism (lis'-tcr-izm) [after Lister, an English phy- 

 sician]. A general name for the antiseptic and 

 aseptic treatment of wounds according to the principles 

 first enunciated by Lister. See Listerian Methods. 



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 points, the distance between 

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

 they 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. 



Liter (le'-ter) [litra, a pound]. The unit of capacity

Lithemia (lith-e f -me-ah) [/j'floc, stone ; difia, blood]. 

 Modified gout. A condition in which, owing to de- 

 fective metabolism of the nitrogenous elements, the 

 blood becomes charged with deleterious substances, 

 principally, perhaps, of the uric acid group, although 

 their exact chemic nature is not determined.

 Pertaining to or suffering from lithemia. 



Lithenate (lith'-en-at). See Lithate.

 mineral 

 In the 



United States, are the Buffalo Lithia Hater, water 



from Buffalo Lithia Springs, Mecklenburg County, 

 Va.; Farmville Lithia Water, from Fannville, Va.; 

 Londonderry Lithia Water, from Londonderry N. H. 

 The proportion of bicarbonate of lithia contained in 

 the three waters mentioned is as follows : London- 

 derry, 8.620, Buffalo, 1.484-2.25, Farmville, 1.99. 



Lithiasic Acid (lith-e-as'-ik). Uric acid, q.v. 



Lithiasis (lith-i' -as-is) \7u6oc, stone]. The formation 

 of calculus, especially of urinary calculus, and of 

 gouty concretions in general ; also the general state 

 of the body that favors such calculous formation. L. 

 conjunctivae, an affection of the eyes characterized 

 by calcareous degeneration of the secretion at the 

 mouths of the Meibomian ducts, commonly seen in

 its high saturating-power makes its salts more highly
