In the following paragraphs some of these resolvable and un- 

 resolvable salts will be described more in detail. 



^ 2. Racemic cis-Diamino-diethylenedtamine-cobalti-chloride. 





Red-brown, well-developed, 

 and very lustrous small crystals, 

 which obviously areisomorphous 

 with the corresponding bromide 

 and iodide.

I? = 87° 56V,'. 



Forms observed: ;'',=: [101], 

 predominant; the external shape 

 of the crystals appears ordinarily 

 flattened parallel to this form, 

 well-developed and very lustrous ; r, = 

 [101], small, but giving sharp reflexes; o=[121] and to = [121], 

 both very narrow, and almost equally developed; « = [100], small, 

 but very lustrous; g'^njOll], mostly narrow, but yielding splendid 

 reflexes. 



Furthermore

m = [jio; 



Perhaps cleavable parallel to m. 



The crystals are only slightly dichroilic, in a way analogous to 

 that of the iodide. They are evidently identical with crystals described
