PRACTICE AND TEACHING OF HYGIENE IN SCHOOLS. 187 



from the already overloaded educaLional argosy in order that its 

 ships may carry the more essential merchandise I have alluded to ; 

 even as flotsam such rare and brilliant gems which the intellectual 

 super-cargoes of the past have so justly valued as the most attrac- 

 tive acquisitions of learning, but which times have changed and 

 the fashions of thought too. The diamond has yielded its secret 

 to the chemist, and gems discarded in the past hold preference 

 and even necessity to the future " Body Corporate of Adventures " 

 who trade in new countries and with new people. 



Bristol never turned out better ships or braver men if you will 

 but find the pilots, take the helm and guide them upon their course, 

 for, as vv'ith the " Adventures " of old the enterprize will yield 

 rich profit. 



THE KARROO SYSTEM IN NORTHERN RHODESIA. 



— Mr. A. J. C. Molyneux, F.G.S., in vol. 65 (1909) of the Quarterly 

 Journal of the Geological Society, traces the extension into Northern 

 Rhodesia of the deposits of Permo-carboniferous age that have 

 been correlated with the Karroo system of the more southern 

 portion of the continent, and goes on to examine into the relation 

 of these deposits to the general geology of the country. A genera- 

 description is given of the geology of the Luangwa, Lukasashi, and 

 Luano Valleys, the Danda Flats and the Lufua River. The rocks 

 of the Karroo system in the Cape Colony and Transvaal are com- 

 pared with those of Rhodesia, and the several series, in the latter 

 case, are individually described. The Basal beds and Boulder 

 conglomerates are correlated with the Dwyka series of the southern 

 portion of the sub-continent, the Lov/er Matobola Beds with the 

 rocks of the Ecca series, the Upper Matobola Beds and Escarpment 

 grits corresponding with the Beaufort series, while with the Storni- 

 berg series of the south are correlated the Tuli lavas and Batoka 

 Basalts together with Forest and Samkoto sandstones, the former 

 corresponding to the Volcanic beds of the series and the latter to 

 the Cave sandstone (the Bushveld sandstone of the Transvaal). 

 The paper is illustrated by half a dozen text figures and a map, 

 together with six collotype plates descriptive of the conglomerates 

 and other members of the series dealt with. 



THE DAYLIGHT COMET, 1910a.— This comet appears to 

 have been first noticed south-west of the sun during the early 

 hours of Friday, January 14, by some miners in the Transvaal, 

 the first measurement of its position being made by ^Ir. Innes at 

 the Transvaal Observatory on the 17th January. With rapid 

 apparent motion it passed to the east of the sun, and was thus 

 distinctly observable without telescopic aid before sunset on the 

 i8th ; both nucleus and tail— the latter being visible to the unaided 

 eye for a length of about 20' — possessing an orange-yellow colour. 

 A second tail was subsequently developed. Spectroscopic obser- 

 vations made at the Lick and Glasgow Observatories revealed 

 bright Sodium lines and a hydrocarbon band.
