and a hornblende rock of a large grain. The last is composed of long- 

 ish portions of hornblende of a shining aspect, which constantly intersect 

 each other, and with this is associated a grey crumbly felspar. To this 

 quartz is frequently added, in which case it forms a variety of sienitic 

 granite. The greenstone schists are of a dark green color and of an 

 uniform texture, they are apparently composed of similar ingredients 

 to the last, but in a more minute state of aggregation. The argillace- 

 ous schists are of a greenish grey color ; they are rather soft, and some 

 of them seem to approach to chlorite schist; scales of mica sometimes 

 occur disseminated through these. The alternating quartz beds fre- 

 quently assume a greenish tint. This is particularly observed where 

 they occur in contact with the greenstone. — N. N. N. &c. represent the 

 above series of argillaceous schists, greenstone schists, &c. The coun- 

 try, after living Nakrum, is characterised by its level and unbroken 

 aspect ; the gently undulating appearance alluded to, being scarcely ob- 

 served on the large scale, and the hills in the neighbourhood of Mangar- 

 wdr more deserve the name of low rounded swells. On leaving Man- 

 ganudr the route lies, for the first five miles, over an uncultivated level 

 plain, covered with soil, and, in one or two instances, outgoings of strata 

 of pure white quartz are observed. From this it is probable that the 

 alternations observed, to the east of Mangarwdr, are continued thus far. 

 About a mile from Hita we observe a very fine-grained granitic rock, 

 composed of a pale reddish felspar, semitransparent quartz, and mica ; 

 the last in very small proportion, and in some situations, entirely wanting. 

 This rock frequently assumes something of the structure of gneiss. — At 

 Hita we also find this granite, and, associated with it, another variety 

 of a larger grain, composed of white quartz, greyish white felspar, of a 

 soft and friable nature, and a very dark colored mica, the last in great 

 abundance. Shortly after leaving Hita, beds of greenstone schist, 

 N. N. approaching to argillaceous schist, alternate with the close-grained 

 granites for a short distance, and afterwards granitic rocks inclosing 

 beds of quartz are alone observed. A similar granite to the lar°-e 

 grained variety of Hita, also, occasionally presents itself, but the mica 

 is in much smaller proportion. As we proceed west the felspar acquires 

 a redder tint, and the large-grained granites here and there are seen : the 

 fine-grained varieties preponderate. The mica in the fine-grained gra- 

 nites is frequently of a greenish color, it also occurs nearly black. Horn- 

 blende too, occasionally occurs : and this, as we proceed west, appears to 

 be replaced in many instances by actynolite, which is found as a consti- 

 tuent of these granites. O. O. 0. the granitic rocks just described, 

 are generally speaking stratified, and many of them have a structure 

 approaching to that of gneiss. This is even observed in several of the
