bichowsky: an unusual sulfur crystal 



those calculated from the Goldschmidt axial ratio. The angles 

 for the rarer faces are: (oio)-(i3o), measured 22° 18', calculated 

 22° 16'; (oio)-(i2o), measured 31° 33', calculated 31° 34'; 

 (oio)-(2io), measured 67° 51', calculated 67° 51'; (oio)-(3io), 

 measured 74° 48', calculated 74° 49'; (oii)-(2ii), measured 

 65° 30', calculated 65° 19'. 



Table i contains a complete list of the faces reported for 

 rhombic sulfur, their discoverer, Miller and Goldschmidt sym- 

 bols, principal Goldschmidt position angles, and the number 

 of times reported in the literature examined.
