the constituent parts; but its colour is of a clearef gre^n : 

 its surface is much rrtore glossy than that of the preceding, 

 and its fracture mare gcntrr-liy imduF^tfed : but! what parti- 

 cularly distinguishes this beautiful speciihcri, which is sev^rt 

 inches long by five broad, is, that it is not only very attraict- 

 able by the magnet, but endo\<^ed with a Strong polarity 

 throughout its wholfe length ; and it attracts keenly al! one.

4. Serpentine of a deep green^ with some sliadeS of ^ 

 cTeai'er green, soft to the touch, but harder than (he pre- 

 ceding, having one of its facets striated, and something like 

 asbestos. 



5. Another serpentine somewhat hard, of a greenish 

 black, with small spots of a greenish white near to each' 

 other,' anid which seem to have a tendency to the parallelo- 

 pipedon form, which gives to this variety of serpentine a false 

 aspect of black and white antique porphyry. But what 

 renders the latter remarkable, is, that it coritains in its sub- 

 sta-^ce, as well as upon its external facets, a multitude of very 

 brilliant small silvery scales of metalloidal appestrance {dial- 

 iage), the brilliancy of which is the more lively, as it shines 

 upon a black ground. This serpentine is strongly attracted 

 by the magnet. 



6. Semi-hard serpentine, attractable, of a deep greenish 

 black, with some laminae of metalloidal appearance like silver, 

 and small layers more or less thin, but some of them a line 

 in thickness, of a substance of the nnctubus appearance of 

 Steatite ; and its colour being olive-green, shining, and of an 

 equal and rich tint, seems to be owing to chrome. 



7. Semi-hard serpentine of a blueish-gtay, with longi- 

 tudinal compressed streaks, covered with a slight and trans- 

 parent couch, or rather with a kind of varnish of a deaf 

 azure blue. We also distovet* rn the fractures bf this beau- 

 tiful serpentine, some scales of a metalloid diallagc, and of 

 a silvery hue ; it is attractable by the magnet. 



8. Serpentine of a deep greenish-gray, semi-hard, feebly 

 attractable, with small round globules, sometimes oblong, 

 of a compact white or greenish substance, harder and more 

 tiojnogeneous than that of the stone which contains them,
