 The saliva of the horse thus presents some differences from 

 that of man, analyzed by M. Berzelius. It contains more albu- 

 men and carbonate of lime, and much less mucus. This ano- 

 maly may, perhaps, be ascribed to the different mode of obtain- 

 ing; the saliva for analysis. That of the horse was procured by 

 dissecting- with care the salivary canal, and receiving the liquid, 

 which flowed out in abundance while the animal was eating. 

 The quantity obtained by this operation, might be estimated at 

 about half a litre. — Ann. de Ch. et de Phys. xix. 174. 



On the Triple Chloride ofGoid and Sodium, by M. Figuier, apo- 

 thecary atMontpellier. — Thisis the medicinal preparation, which 

 Dr. Chrestien, of Montpellier, has been in the habit of employing. 

 If to a solution of chloride of gold, made with two ounces of this 

 metal, weadd four drachms (about 300 grains troy) of decrepitated 

 sea salt, and evaporate, we obtain a salt perfectly crystalline, con- 

 taining always the same proportions of gold, which, far from at- 

 tracting humidity, like the simple chloride of gold, is on the con- 

 trary nearly inalterable in the atmosphere, and not liable to 

 change its nature by repeated crystallizations. M. Figuier de- 

 termined the quantity of gold in this salt, by throwing it down 

 with sulphuretted hydrogen ; he found the muriate of soda pre- 

 sent, by evaporating to dryness the supernatant liquid of the 

 preceding experiment ; and thirdly, he ascertained the propor- 

 tion of chlorine, by nitrate of silver. By this process he found, 

 that the chloride of gold and sodium contained, 



Chloride of gold 69.3 



Chloride of sodium 14.1 



Water • . . . . 16.6

He then shews that calling the atom of gold 248.6 with Ber- 

 zelius, a triple chloride which would be formed of one atom of 

 chloride of gold, one atom of chloride of sodium, and eight 

 atoms of water, would have for its constituents.
