mens of wollastonite ticketed zurlite. I have lately been favoured 

 by Mr. Monticelli with specimens of zurlite^ a green mineral, and 

 bearing no resemblance to wollastonite, or to any specimen I have 

 before observed. 



The late Mr. Phillips, in his Elements of Mineralogy, gave a 

 figure of a supposed crystal of the flexible silver of Bourn on, dif- 

 fering altogether from Bournon's figures. The specimen from which 

 that crystal was taken was said to be Bournon's mineral; it is, how- 

 ever, sulphuret of silver, and the figure given by Mr. Phillips is 

 evidently a distorted modified cube. I have lately obtained a 

 specimen of Bournon's flexible silver, so named by himself, from 

 which it appears to be the same mineral as the sternbergite of 

 Haidinger. 



Mr. Phillips also gave a figure of xuhite tellurium from a crystal 

 he received from me. It is not, however, certain that this crystal 

 is the mineral commonly so named. It is very minute and brilliant, 

 and silver white, and there are many similar to it in the cavities of 

 a small group, in my possession, of very distinct crystals of foliated 

 tellurium, one of which was also figured by Mr. Phillips. Perhaps, 

 among the larger collections of the ores of tellurium, these white 

 crystals may occur in sufficient quantity for chemical examination. 



ON THE JUICE OF ESCHSCHOLZIA CALIFORNICA. 



Not being aware that any scientific author has made mention of the 

 very peculiar jwfce contained in tha;t beautiful plant the Californian 

 Eschscholzia, I beg to call the notice of the medical and chemical 

 readers of the Philosophical Magazine to this point. The juice is 

 of a yellowish colour, and is given out very readily from the stems 

 and other parts of the plant ; it smells exactly like muriatic acid, 

 and possesses in some degree the property of taking out ink-spots 

 from linen, &c. 



This plant is a species of the new genus Eschscholzia, belonging 

 to the natural order Papaveracece ; and, like some of the same order, 

 the common Celandine (Chelidonium majus) and the Opium Poppy 

 (Papaver somniferum), for instance, it has a similar powerful juice, 

 which 1 think probably may hereafter, hke theirs, become of use to 

 the physician, as well as of service to the chemist. 



For this reason, may I beg that the Editors will give these lines 

 a place in their Magazine ; hoping that as the Eschscholzia Cali- 

 Jbrnica is now common in many of our gardens, a chemical analysis 

 of its strong juice, and the experiments consequent thereon, may 

 develop the causes of its muriatic-acid-like scent, and perhaps ren- 

 der it beneficial in medicine.

ANALYSIS OF NADELERZ. BY HERRMANN FRICK. 



The mineral examined was found in the gold veins of Beresow in 

 the Ural, hitherto the only known locality of it. It occurs com- 

 monly disseminated in quartz in very slender acicular prismatic 

 crystals, deeply striated, and exhibiting an imperfect cleavage pa-
