M^ ^5^' Small and irregular-shaped fragmonls, of a greer.i'ih OjIot, probably due to malachite; one bong com- Ijfsct, the other pr>rphyritic. Two of the latter oontain crystals lup to about }h inch diameter) ot a Uaddsh min- eral, which j/Toves to be a very dark hornblende with a rather small extinction angle; the same mineral, bat of a smaller size, occurs in others. They aie Tarieties, rather dtcffmjjfj^sed, of andesites, mostly homUendic. (6). Part of a rather smoothed subangular fragment ci... sl a/mfjact oli%'e-green rock, in which are some very small dark pri-sms. Probably a homUende-andesite, slightly stained with malachite. (7), An elongated triangular fragment, defined by joint faces, showing some very small crystals of fdspar in a compact matrix. An andesite. (8), (9).
