V. — New Pharmaceutical Preparations, 



Employment of white oxide of lead in tic douloureux. — This 

 oxide has been employed in France with great success in the painful 

 affection of the face, known by the name of tic douloureux. A 

 layer of the following mixture 



Ceruss, 1 ounce. White oxide of lead 2 or 4 gr. 

 is applied to the part affected, to the depth of half a line. The 

 intensity of the pain speedily subsides, and gradually dissappears. — 

 Journal de Pharm. xx. 603. 



Collyrium of Nitrate of Silver of Dr. Munaret. — Take of 

 saturated aqueous solution of nitrate of silver iv. gr. 



Distilled water, 1 ounce. Laudanum, iii. gtt. 



This is very useful in chronic inflammation of the conjunctiva, and 

 even in the acute inflammation of the globe of the eye. The action 

 may be assisted by leaching and aperient medicines. 



The Boletus Larycis, or white mushroom, is recommended by M. 

 Andral, in colloquative sweats. He prescribes it to the extent of 48 to 

 60 gr. made into pills of 8 gr. each, without observing any effect upon 

 digestion, although it was long supposed to be a drastic purgative. 



M. Pouche has found the Cyanuret of gold, useful in siphilis and 

 scrophula. M. Figuier recommends that in preparing this compound 

 the chloride of gold should be neutral, that the cyanuret of potash 

 should not be alkaline, and should be free from formate and car- 

 bonate of potash. What remains after the calcination of ferro-prus- 

 siate of potash in close vessels answers very well, when dissolved 

 and carefully precipitated with the salt of gold, avoiding any excess of 

 the potash salt. M. Pouche rubs it on the tongue mixed with an 

 inert powder, such as iris of Florence washed with alcohol in the 

 proportion of 1 gr. cyanuret of gold to 3 gr. powder of iris. In the 

 form of pills it may be given in the following : Cyanuret of gold 1 gr. 

 Extract of daphne mazereum 3 gr. Powder of Mallows q.s. for 5 pills. 



For children it may be made up 



always begin with -^-th of a grain.
