to £2,233,161 2s. M., showing a considerable increase over the 

 previous year, of which minerals, after coal, tin yielded the largest 

 amount, £508,540, exceeding that either of gold or copper, the other 

 metals, iron, antimony, and lead, being in far less proportions. 



2. The work by the Eev. W. B. Clarke is probably the last of the 

 published results of his labours before his death (noticed p. 379), 

 and is only one among his many contributions to the advancement 

 of geological science, especially that of Australia, which has occupied 

 a considerable portion of his life. The present edition is the fourth 

 of a series, descriptive of the sedimentary formations of New South 

 Wales, the first of which was published in a catalogue of the natural 

 products of the colony forwarded to the Paris Exhibition of 1867, 

 and subsequently improved in the 2nd and 3rd editions (1870, 

 1876). It is now considerably enlarged, and contains much fresh 

 information brought up to the latest period, and is dedicated to the 

 Congress of Geologists assembled at Paris in connexion with the 

 International Exhibition of this year. The formations noticed are, 

 the Azoic and Metamorphic rocks, the Lower, Middle, and Upper 

 Palaeozoic rocks, the Lower and Upper Mesozoic strata, and the 

 Tertiary rocks, — of the latter it appears that " throughout the whole 

 of Eastern Australia, including New South Wales and Queensland, 

 no Tertiary Marine deposits have been discovered. There are, 

 however, patches of plant deposits which may be referred to some 

 period of the Tertiary epoch," (p. 89.) The Quaternary formation, 

 so interesting from the remarkable fossil remains found in it, and 

 the recent accumulations, are noticed in the last section. In this 

 memoir no general notice is taken of igneous rocks, but it may be 

 stated that there is, in all the various sedimentary formations noticed, 

 distinct evidence of the presence of igneous action, and their trans- 

 mutation through such and allied agencies has left an impress on 

 all the rocks more or less concerned. 



Those interested in the comparative study of the sedimentary 

 strata will find Mr. Clarke's paper of considerable value, as showing 

 the results of a continued study of the fossiliferous deposits of 

 Australia, — one of which at least, the Carboniferous formation, has 

 been the subject of some controversy, the main points of which are 

 fully discussed by the author, both as regards its contained fauna 

 and flora, and its connexion with other deposits in Australasia, 

 China and India (pp. 26-66), and which, as well as the remarks on 

 other formations, are supplemented by fifteen appendices containing 

 lists of fossils of New South Wales described by European palgeon- 

 tologists. 



IV. — The County of Edinburgh, its Geology, Agriculture, and 

 Meteorology. By Ralph Richardson, F.R.S.E. (Edinburgh: 

 Adam and Charles Black, 1878.) 



THIS essay fulfils what the title indicates, an account of the 

 geology, meteorology, and agriculture of the metropolitan 

 county of Scotland, preceded by some general observations on its 

 physical features, superficial area, subdivisions, and annual value of
