We are all aware that it is very often much easier to put a question than to obtain an entirely satisfactory answer, and I am consequently sorry to have to begin my few observations on a very extensive class or group of organisms, by stating that zoologists and comparative anatomists have not yet entirely agreed as to the exact position it should occupy among invertebrate animals.

Since the Government Geological Survey of the country around Nottingham was made in the year 1859, and the Explanation on the Geological Map Quarter-sheet 71 N.E. was written in 1861, papers by local geologists have been written, stating that in the neighbourhood of Nottingham a perfect conformity existed between the Magnesian Limestone and the New Red Sandstone. This being totally at variance with conclusions I came to when I surveyed that country, I have been for some time past desirous to say a word on the subject, but being deeply occupied with the old rocks of the Lake district, I have put it off from time to time. I felt little doubt in my mind, when surveying the neighbourhood of Nottingham, that there was a considerable break between the Magnesian Limestone and the New Red Sandstone, and this opinion was completely confirmed as I continued my survey northwards through Nottinghamshire into Yorkshire.

The publication in the last Quarterly Journal of the Geological Society of the most instructive paper by Messrs. S. V. Wood, jun., and F. W. Harmer, on the Later Tertiary Geology of East Anglia, and one by the latter author on the Kessingland Cliff-section, induces me to offer the following remarks, with the hope that my views may be considered by geologists who have made this question their study.

I have been fortunate enough to obtain from the eastern slope of Mount Hermon (Jebel esh Shech) a large lot of fossils, which not only determine the geological position of that part of the Lebanon, but also settle the question of the existence of Jurassic formations in Syria. Of course it has been often enough asserted that Jurassic rocks are found here, but the fact has not been considered settled beyond doubt.

Baron Ettingshausen has forwarded to me from Graz a series of papers, relating more especially to the Fossil Floras of the Tertiary Periods. We have been made familiar with these mainly through the translations of the works of Heer, Unger, and De La Harpe; but to most of the readers of this Journal the work and opinions of other continental palaeontologists, such as Ettingshausen, Massalongo, and Saporta, are unknown. It may, therefore, not be out of place, pending the contemplated publication by the Palseonto-graphical Society of a monograph on the British Fossil Eocene Flora, to give in the GeologicalMagazine a brief analysis of their theories.
