الصفحة 5 - ... assumed that the 17.6 cc. of milk taken for the determination will weigh 10 times as much as 2 cc. of warm butter fat. It is important that the final readings be taken while the fat is still warm. On account of the unavoidable contraction of the fat while taking these readings it is customary to read from the bottom of the lower to the top of the upper meniscus. The result is usually within 0.2 per cent of that found by the gravimetric method. The column of fat should be of a clear yellow color...
الصفحة 11 - Eimmeridge district ; where it is upwards of 600 feet thick, and strongly impregnated with bitumen, giving out a disagreeable smell. It burns vividly with a bright and clear flame, but is unfit for ordinary use as fuel ; the poor of the neighbourhood, however, use it as a substitute for other fuel.

The remainder of the Upper Purbecks consists of a series of bands of clays and stone, the...
الصفحة 16 - FRS, stimulated by these discoveries, proceeded to make a close and systematic search in the fresh-water marl-beds, and with complete success. In three weeks he brought to light, from an area forty feet long by ten wide, and from a layer the average thickness of which was only five inches, several species, many of which were new. They are the subject of an exhaustive memoir by Professor Owen, in the Palteontographical Society's works for the year 1870.
الصفحة 12 - Bingsteacl, and, owing to the rock losing its shaly character, the fossils are well preserved. The beds have a northward dip, and are, as already noticed, intersected by numerous faults, causing dislocations, analogous to those of the Coal-measures. The distinctive character of this formation, as compared with the true Carboniferous, is, that the bituminous matter is principally a result of the decomposition of animal matter. Like the Lias of the western side of the county, it yields a rich supply...
