The following are the new forms, briefly described: 



a = oo = jl00*. The orthopinacoid was noted twice, once as 

 a broad face and once as a narrow face. 



h = 2co = |210f. This prism was noted on three crystals, as 



rather large faces. 

 / = | co = \ 320 1 . On crystal No. 1 was noted a small face in 



the prism zone, the measurement of which agrees well 



with the calculated value, though the reflection was very 



poor. 



/ = co 2 = [ 120 \ . This prism always occurred with and 

 was about equal to it in size. Crystal No. 15 showed the 

 three new forms, a, h and in the prism zone. 



v = +10 = j 101 1 . Only once was this form noticed, as a small 

 face with a poor reflection. 



<J = — f = \ 205 \ . This dome also occurred but once as a rather 

 large face. It gave a good reflection. 



r = +1 = Sill!. The unit pyramid was represented by a long 

 narrow face, giving a good reflection.
