proportions of the original, which measured l cm in length by 

 5 mm in maximum diameter. A number of fragments showing 

 partial terminations were also measured and a list of the forms 

 found upon them is presented in the table. The list includes 



most of the forms previously observed on zoisite and a number 

 of new forms of which a few are well established by the data 

 observed. 



In the prism zone the dominant forms are m and b, present 

 on every crystal ; a, k, q, and I are also frequently well de- 

 veloped. The remaining prism forms are present only as 

 narrow line faces and, as the zone is striated, are somewhat 

 uncertain forms. Where they occur with several faces of each 

 symmetrically developed on a single crystal and in good agree- 

 ment with calculated position, they have been accepted as good 

 forms.
