Spiranthes Niiil. Richard. Orch. ann. 

 Circa Valparaiso, Februario florentem, legit McRae. (v. s. sp.) 

 General appearance of the plant like that of the Siberian Spiranthes 

 congesta. Leaves oblong-lanceolate, stalked, resembling those of Pe- 

 lexia adnata, but smaller and erect. Stem a foot high, clothed with 

 acuminate squamae, hairy at the upper part. Spike crowded, ovate- 

 acuminate, with taper-pointed bractese longer than the flowers. Sepals 

 downy externally, the three upper of equal length and firmly aggluti- 

 nated together, the two lower spreading, distinct. Lahellum erect, 

 sessile, recurved, membranous, crisp, with very strong bifurcate veins, 

 and two calli at the base, which are linear and obtuse, and apparently 

 veiny also. Columna unusually short, with a retuse rostellum, and a 

 large roundish cordate anthera. 



A Dictionary of Chemistry, and of Mineralogy as con- 

 nected with it, in which is attempted a complete List of 

 the Names of Substances, according to the present as well 

 as former Systems ; with an Introduction, pointing out 

 the order in which the chief parts of the work may be 

 perused, so as to constitute a regular Course of Chemistry ; 

 and a Focabulaiy, in which the apparatus and processes 

 made use of are briefly described, — with copious Notes, 8fc.

 This verbose title is, we are sorry to say, the prelude to a 

 very inadequate performance, — to a mere chemical scrap- 

 book. The task of writing a dictionary of chemistry is, at 

 the present day, serious and difficult ; and should only be 

 undertaken by those who are well read in the science, and 

 wlio, with just and accurate information of what has been 

 done by others, conjoin practical skill, experimental dexte- 

 rity, and much personal observation of the processes of the 

 chemical arts.
