42. Additional I^otes on E-ocks and Possils from Franz Josbe 

 Land. By E. T. IS^ewton, Esq,, E.E.S., F.G.S., and J, J. H. 

 Teall, Esq., M.A., E.E.S.,V.P.G.S. (Kead June 22nd, 1898.) 



[Plate XXIX.] 



In our previous notes ^ an account was given of the rocks and 

 fossils which had been collected by Dr. Koettlitz and sent home in 

 1896. Another large series was brought back by the same gentle- 

 man on the return of the Jackson-Harmsworth Expedition in 1897. 

 These specimens have been examined, and it is satisfactory to have 

 to report that they confirm our previous conclusions, necessitating 

 no modification of our previous notes, except as regards some of the 

 altitudes at which the specimens were obtained ; these, however, do 

 not alter the relative positions of the beds. At the same time, 

 there are some additional facts which it is desirable to place on 

 record. 



The corrected measurements of altitudes are given by Dr. Koettlitz 

 on a preceding page (p. 636), and these, it will be seen, alter materi- 

 ally the position of the beds at Cape Gertrude as given in our 

 section. There are two errors on p. 503 of our previous paper 

 which we desire to correct. On line 4 the 100 feet of basalt refers 

 only to what is seen in the cliff-section, and on line 9 ' highest ' 

 should have been printed ' lowest,' which will be found to agree 

 with the section and the measurement that we then had. 



I. EOCKS. 



A very large number of rock-specimens have been examined, but 

 as these belong, for the most part, to varieties already described in 

 our former paper, it will be unnecessary to refer to them at any 

 length in these general notes. 



The common type of basalt is evidently very widely distributed, 

 for it occurs as far west as Cape Mary Harmsworth. In view, of 

 the wide distribution of this type it was thought desirable that it 

 should be analysed, and the specimen represented in fig. 1, pi. xxxvii, 

 Quart. Journ. Geol. Soc. vol. liii (1897), was selected for this purpose. 

 It yielded the following result : — 



I. Basalt, Cape Flora (Teall). 

 II. Do., from the rock-wall, Almannagja, Iceland (Bunsen). 

 III. Do., from the north-eastern coast of the island of Vidfrey, Iceland 

 (Bunsen). 



1 Quart. Journ. Geol. Soc. vol. liii (1897) p. 477. In both papers Mr. Teall 

 is responsible for the petrology and Mr. Newton for the palaeontology.
