He gives also a list of nearly forty planes which he has ‘sen 
upon the crystals under examin nation, The crystals have a pet- 
fect cleavage parallel to the clinopinacoid fe the habit ve 
rom medium to short columnar, the unit prism ordinarily pre- 
dominating; a striking feature is their resemblance in form to 
jection. It is not often that a new Cet species admits of so 
thorough a rete oR nC examination. Prof. Jackson states 
that the locality from which the crystals examined came was 
Calico District, San ae Co., California fae Death Valley, 
where, however, the mineral also occur s). 
The chemical analyses by Mr. J. T. eye have led to the 
formula 2CaO, 3B,0,+5H,O or Ca,B,0O,,+5H,O; it is very near 
both priceite and aes (See ‘Syst. ‘Min, , App. II, III), from 
the latter it differs in containing two molecu es more water. 
e same mineral has been studied by several other mineralo- 
gists, and their results confirm those of Professor 4 scmmg though 
made on a smaller selection of material; see th
