Fis. 13. Schizolite. 



l. Flattened after e{00l} (figure 12). 



The combination rather simple: a{lOO}, &{010}, c{00l}, 



«{Toij, iV/{lTo}, and 

 ^(l20}, which latter face 

 has not otherwise been 

 found in the mineral. 



2. Flattened after a {lOO} 

 (figures 13 and 14). 



The combination in 

 fig. 13: a{lOû}î 6{010}, 

 c{00l}, w{rOl}, ш{110}, 

 i¥{no}, and p {230} ; the 

 lastnamed face has not 

 been found in other forms. 



In fig. 14 are found: 



f<{lOO}, 6{010}, c{00l}, 



ш{110}, i¥{lTo}, w{roi}, >{Г02},(/{ТГ1}, /■{T4^l}, andejni}. 



3. Flattened after è{0 10} 

 (figure 15); a rather large 

 and well developed cry- 

 stal in which are found: 

 a{]00}, è{010}, c{00l}, 



4Г11}, n{roi},j{Tri}, 



r{l02}, and s{20l}. 



4. Lengthened after the 

 c-axis (figures 16 and 17). 



Combination in fig. 16: 

 rt{lOO}, ô{OIO}, c{00l}, 

 iV/{lT0}, n{\0\}, г{Г02}, 

 and (/{ill}, in fig. 17 : 

 a{l00}, b{010}, c{00l}, 

 ш{110}, n[m], r{l02}, ^{TTl}, and f{\^\}. 



Twin crystals. The small crystals from Kangerdluarsuk 

 are very often developed as twins , exactly after the same law
