tions, cuprum ammoniatnm and liquor 

 cupri ammoniati ; and iron several addi- 

 tional forms. 



Among the distilled waters, the aqua 

 anethi is banished, and the aqua carui 

 introduced in its stead. 



The addition to the chapter of decoc- 

 tions is numerous, and consists chiefly in 

 a form of this kind for the dulcamara, 

 lichen, senega, and veratrum. 



To the infusions there is also a very 

 numerous addition : angustuva, cloves, 

 cascarilla, cinchona, columbo, quassia, 

 rhubarb, simarouba, tobacco, digitalis, 

 tar, horse-radish, each becomes a sepa- 

 rate subject of this mode of preparation. 



Among the mucilages, that of traga- 

 canth is omitted. 



The extracts afford us new prepara- 

 tions in the hop (huinulus lupulus) poppy, 

 sarsaparilla, dandelion (taraxacum), and 

 hemlock. 



The mixtures give us a new form for 

 gum guaiacum. 



The spirits revive the old spiritus 

 anisi, and spiritus raphani, the latter un- 

 der the newer name of spiritus armoracise 

 compositus. 



The chapter of tinctures provides a 

 new form for capsicum, digitalis, humu- 

 lus, hyoscyamus, kino. 



The aceta give us a form for the col- 

 chicum. 



The syrupi provide a form for the le- 

 mon, and order the syrupus papaveris 

 somniferi to be prepared from its ex- 

 tract. 



The term confectiones is intended to 

 embrace equally, electuaries, confections, 

 and conserves : from this chapter several 

 of the existing forms are banished. 



The list of pulveres is also considera- 

 bly diminished, chiefly by a rejection of 

 several of the cretaceous preparations. 



Among the pilulae we now meet with 

 a gamboge pill : the opium pill is ba- 

 nished. 



The list of emplastra is diminished in 

 a few forms, and enriched by a new Pre- 

 paration, entitled emplastrum thuris cum 

 opio. 



The cerata are increased by a ceratum 

 sabinae, and C. vesicatorii. 



The unguenta are much diminished ; 

 several of those, indeed, in the existing 

 Pharmacopoeia being transferred under a 

 different preparation to the chapter of 

 cerata : while as new articles we have 

 an U. hydrargyri nitrici, U. hydrargyri 

 nitrico-oxydati, and U. veratis. 



The liniments give us as a new prepa- 

 ration, a lin. aeruginis. 



The cataplasms offer us a new form for 

 one prepared from meal and yeast, under 

 the title of C. effervescens.
