Kokscharov reviews the angles of chlorite crystals as given by other 
observers. Ina chlorite from Zillerthal, P : mR= 104° 10’/—104° 20’, 
G. Rose. }R gives for this angle 104° 15’. P(OR) : aR 196° 32’, 
near 126° 35’ an fats deduced from Descloiseaux’s measurements of 
a Zillerthal crystal. Breithaupt gives the angle for the terminal i 
of a rhombohedron 106° 16’ 15”; this gives OR : mR=136° 9 17"; 
and mR therefore equals 2R, which gives OR : 2R = 136° 2' 50’. 
Lophoite of Breithaupt has the angle OR : mR=105° 14’—105° 25/, 
and Descloiseaux calculating from the pyramidal angles 132° 40’ and 
106° 40’, obtained 105° 33’. mR in this case equals 2R, and OR: $R 
=105° 32’, 
Pennine gezending to Frobel gives the angle OR : mR=99° 0’; this 
corresponds to +4R; OR: +4R—99° I’ 16”. Descloiseaux makes this 
angle 100° 30’ 40”, which, would correspond to 12R; OR: 12R=100°
