Notes on Hock Specimens i-ko.m rNYouo. 

 By Mk. G. T. I'kiou, Natlkal IIistokv Mlskc.m. 



The specimens from Unvf ro in Sir Harry Johnston's collection of rocks from the Uf^anda 

 Protectorate con.sist mainly of a series of ferruginous shales, varying in colour from pale i)rown 

 and purple to deep brick-red, and sometimes banded with black lyddites and a few softer and 

 more scliistose phyllites. 



These rocks present strikino' similarities with Hatch's " Hospital Hill " series of the 

 Southern Transvaal, and also with rocks from the Ingwenya I'erg, Swaziland. The "Hospital 

 Hill" series of ferruginous slales occurs in the neighbourhood of Johannesburg as part of 

 Hatch's Cape system with the Witwatersrand auriferous quartz-conglomerates immediately 

 above it. [^Quarterly Jnurnal (reological Society, iv. 18fls, if. 7;{, 99.] 



The Swaziland ferruginous sliales, or "argillites,'' which probably belong to the same 

 series, occur in association with gold-bearing serpentine and talcose schists. [Geolo/jical 

 3Iar/a:inr, vi. 1899, pp. 105-111 ; the rocks marked T. B. in Professor Rupert Jones's list.] 



Amongst the rocks from Unyoro is a .specimen of quartz which certainly presents some 

 points of resemblance with that of the auriferous Banket formation ot the Transvaal. Although, 

 in the absence of their field-relations, it is not advisable to lay too much stress upon the 

 resemblance of these rocks from Unyoro with the "Hospital Hill" series of the Transvaal, 

 yet the similarity of the rocks is sufficiently striking to suggest the idea that // gold /•< /t> be 

 found ill the Uganda Protectorate, Ungoro is the most likely district in which to looh for it.
