road between Alexandria and Cairo, requesting him to procure for 

 me as many organic remains as he could from the Nummulite Lime- 

 stone of the Mokattam range, at the foot of which Cairo is situated. 

 He kindly complied with my request, and among other specimens 

 which he sent there were some Ichthyolites. These I was anxious 

 to have examined by my friend Sir Philip Egerton, our highest 

 authority in this country in that branch of Palaeontology. With 

 his usual readiness, he has given me tbe benefit of his opinion ; and 

 I was desirous that his valuable communication should at once be 

 made known to the Geological Society. — Leonard Horner.

The valuable contributions to our knowledge of fossil entomology 

 recently published on the Continent, and more especially the admi- 

 rable work of INI. Heer of Zurich, appear to have led several of our 

 English geologists to take up that branch of Palaeontology with more 

 energy than at any previous period ; the result of which has been 

 shown not only in the large collections of Lias insects made by 

 the Rev. P. B. Brodie, which formed the groundwork of his ' History 

 of the Fossil Insects in the Secondary Rocks of England,' published 

 nearly ten years ago, but also in the discovery of some traces of 

 fossil insects in the Hastings series of the Isle of Wight by Professor 

 Edward Forbes, — a large number of insects in the Wealden rocks of 

 Hastings and its neighbourhood by Messrs. W. and H. Binfield *, — 



* Quart. Journ. Geol. Soc. vol. x. p. 171. A rich collection of fossil insects, 

 from the Lias of Gloucestershire, &c., has been made by ^y. R. Binfield, Esq., to 

 whom also tbe Museum of the Geological Society is indebted for a suite of insect
