3. Notes on some Sections in the Old Eed Sandstone and Ballagan 

 Series in Dumbuck Glen. By Mr. John Yomig. — Mr. Young stated 

 that the sections exposed in Dumbuck Glen belong to the Old Eed 

 Sandstone, and to a series of thin-bedded limestone strata, locally 

 known as the Ballagan beds, from being typically developed at the 

 Spout of Ballagan, near Strathblane. The latter are by some 

 geologists considered to be of Carboniferous age, and by others as 

 belonging to the Old Eed Sandstone. The only evidences of organic 

 remains yet found in them are fragmentary fish scales, plants, and 

 annelide impressions. — Glasgoio Herald, 19th January, 1867. 



Literary and Philosophical Society, Manchester. January 

 8th, 1867. Edward Schunck, Ph.D., F.E.S., etc.. President, in the 

 Chair. Mr. Binney, F.E.S., F.G.S., exhibited two remarkable 

 fossils, discovered by Mr. Joseph Tindall, of Thomas-street, Hud- 

 dersfield, in the Lower Coal Measures near that town. One was an 

 insect, and, according to Mr. Tindall, belonged to Dr. Dawson's 

 genus Xylohius and probably to his species Sigillarm. It was found 

 in an old deep mine at Cooper Bridge, and is the first instance of a 

 specimen of that genus having been met with in England.' The 

 other bore some resemblance to the pupa-state of a Coleopterous 

 insect, not much unlike the piipa of a nut-weevil or some such 

 insect. It was found in the Cindertield Dyke Pit, at Bradley, near 

 Huddersfield. These specimens give us evidence of the former 

 existence of insect life during the Carboniferous epoch which a few 

 years since we should scarcely have expected ; but after the dis- 

 covery of a fossil spider in the German Coal-measures, scarcely to be 

 distinguished from a recent genus, we must expect great additions to 

 be made to the Carboniferous fauna, as doubtless the rich and 

 luxuriant vegetation of that remote period would afford food and 

 shelter for numerous insects. — Proceedings — Lit. and Phil. Society.

THE LATE ME. F. J. FOOT. 

 To the Editor of the Geological Magazine. 



Sir, — Will you allow me to correct some inaccuracies in your 

 obituary notice of my late lamented colleague, Mr. F. J. Foot. 



The date of his appointment to the Survey was August 1st, 1854, 

 not 1856. 



Sir Henry De la Beche died on April 11th, 1855, but continued his 

 annual visits to Ireland to the last, and I well recollect his expres-

 by the late Mr. Thomas Brown, was described by Mr. Henry Woodward, before the 

 Glasgow Geological Society, on the l7th January, 1867. — See Eeport of that Society,
