Axiuite was recorded from this Ljcality l)y Mr. D. A. Pt>rter' 

 ill 1884 ; at that time its occurrence in situ was not known, but 

 recently Mr. Porter has traced it to its parent rock at a point 

 <about two miles south-east from ^toonbi Railway Station. The 

 mode of occurrence is practically the same as that of the Bowling 

 Alley Point axinite ; from a genetic point of view the two are 

 probabl}' identical. 



One of the Museum specimens is full}^ as large as ones fist, ami 

 entirely composed of somewhat coarse crystals which are often 

 built up of several individuals in approximately parallel ixisition. 

 recalling the sheaf-like aggregates so common with stilbite. 

 Smaller crj'stals adapted for goniometric determination were 

 obtained from crevices, where, as at Bowling Alley Point. the\- 

 <ire accompanied by crystallised quartz. 



Two fragmentary crystals, each between '2 and 3 mm. l<ing. 

 were measured, and drawn (PI. xxxi., figs. 1, 2) according tf) their 

 natural development. The zone [010, 111] was made e(|uatorial 

 as before, and the normal angles obtained by calculation from the 

 measured co-ordinates. The habit is similar to that of the 

 Nundle axinite, and /• (111) is, as in that, striated j)arall('l to it^ 

 intersection with J/ (110).

This occurrence was first put on record by ^Messrs. Petterd and 

 Twelvetrees in their paper " On the Occurrence of Linnu'ite in 

 'Jasmania."^ In that paper and two supplementary notes"' the 

 authors have discussefl the field relations and microscopic 

 4-haracters of this interesting axinite-bearing rock, which is 

 jiaralleled only by the original limurite of the Pyrenees.''
