ABSTRACT Artwork in The Geology of Russia (1845) documents the extent and fossil content of several Paleozoic systems in Europe and large tracts of Russia. That artwork conveys a sense of landscape, portrays the distribution of strata both at and below the surface, and documents the fossil evidence for identifying several Paleozoic geologic systems. The artwork includes wood engravings, lithographs, zincographs, and copper plate engravings. The choice of technique was governed by the content and desired character of the images and the logistics of printing. Roderick Murchison was a master of organization who commissioned, assembled, and oversaw the production of artwork that was crucial to presenting the evidence for the Paleozoic systems documented in The Geology of Russia (1845).

SUMMARY R. E. Grant's advocacy of transmutation is considered in relation to the scientific climate of the 1850s. To understand the palaeontological framework of his development theory, the unpublished “Palaeozoology” lectures, delivered in 1853–7, are analysed and his sources tabulated. The lectures are shown to contain the following additional themes: (1) a refutation of Lyell's steady-state geology, (2) support for serial development, (3) use of metamorphic effacement to explain the lack of pre-Silurian fossils, and (4) nebular hypothesis. The difficulty of supporting serial development using fossil evidence at this late date is discussed, and this difficulty is deemed to have contributed to the failure of Grant's theory of species “generation”.

The Relationship

The purpose of this paper is to re-examine the relationship between the degree of aggregate labour-intensity and the aggregate volume of saving in an economy where a Cobb-6ouglas production function in its traditional form can be assumed to give a good approximation to reality. The relationship in ques¬tion has an obviously important bearing on economic development policy in the area of choice of labour intensity. To the extent that and in the range where an increase in labour intensity would adversely affect the volume of savings, a con¬flict arises between two important social objectives, i.e., higher rate of capital formation on the one hand and greater employment and distributive equity on the other. If relative resource endowments in the economy are such that such a "competitive" range of labour-intensity falls within the nation's attainable range of choice, development planners will have to arrive at a compromise between these two social goals.
