Some of these natural casts are nearly 3| feet long, indicating not merely 

 the imprints of the toes, but also of the sloping metatarsals. The animal 

 must have been of great size and weight, leaving deep imprints. Little 

 trifid imprints of only 3 inches in length, with a stride of about 13 inches, 

 occurred to the author also in the Isle of Wight. He kas found, also, 

 triads of the usual size in the TTealden of Swanage Bay. Mr. Beckles 

 argued that other Dinosaurians besides the Iguanodon have left these 

 track-marks ; and he stated that from the first he has been accustomed to 

 associate them with the various phalangial bones so abundant in th.e 

 Wealden. 



9. Geological Xotes on Zanzibar." By Eichard Thornton, Esq. 

 From the coast to the coast-range (600 to 1300 feet high), the country 



consists of a series of strata with an easterly dip, namely (from above 

 downwards), coral-Hmestone, sandstone, yellow shale, and sandstone with, 

 plant-remains. The mountain Kilimanjaro is formed chiefly of volcanic 

 rocks. White and altered sandstones, with easterly dip, are met with also 

 in the Massai Plain. 



10. " On a Section at Junction-road, Leith." By TV. Carruthers, F.L.S. 

 The author stated that in the section of clay, sand, and gravel near 



Leith, described by Mr. Geikie as part of a raised beach elevated since the 

 period of the Soman occupation, not only have mediaeval pottery and 

 tobacco-pipes been foimd in the potterj'-bearing deposit described by Mr. 

 Geikie, but a media-val jar has been met with in the sand beneath. The 

 so-called *'• Eoman " pottery was stated by the author to be of medieval 

 age. on the independent authority of Messrs. Birch and Franks, of the 

 British Museum ; and he believes that the beds m question are maitdy of 

 late and artificial formation ; he does not, however, argue from this that 

 there is no evidence of a late upheaval of the central part of Scotland. 



11. " On the Death of Fishes in the Sea during the Monsoon." By Sir 

 William Denison, Governor of Madras, etc. 



S teaming between Mangalore and Cananore, on the west coast of India, 

 ftie author found that for some time after the south-west moLjsoon the sea 

 Was offensive with dead fish, killed by the great mass of fresh water poured 

 into the sea during the season of the monsoon. 



Specimens Illeplias Melitensis and JTyoxus ATeVdensis, obtained from 

 bone-caves in Malta by Captain Spratt, were exhibited by Dr. H. Fal- 

 coner. 



^Ij-NCHestee Geological Society. — Jifay 27. — Mr. Binney read "An 

 Account of the Excursion to Todmorden." On reaching Todmorden, the 

 party proceeded along that beautiful vaUey to Gauxhokne, over strata 

 belonging to the lower porrions of the millstone grit. At the entrance of 

 Dulesgate stronii gritstone rock was seen dipping at a considerable angle 



.W., and exiiibiting shakes and faults. On Pendie Hill, beyoDd Bui-nley, 

 and at Tiutwistle, near Giossop, are two natural sections which can be 

 pretty well meastu'ed. especially the latter, where, between Bhodes Wood 

 Quarry in the valley, and the thick bed of rock at Tintwistle !!Sar on the 

 hiU, are from 700 to 80() feet of strata. The whole of the deposits between 

 the limestone shale and the upper millstone of the Lancashire geologists 

 (the Brooksbottom Sandstone) may be taken at 12CK) feet in thickness. 

 These beds probably auain their greatest deveiopme^Lit in Lancashire, 

 Yorkshire, and Cbeshu'e. Beturning again to the Gauxbolme Bock, a small 

 seam of coal was observed, and at a farther distance up the valley another 

 bed of a few inches. From tiie entrance of the valley to the quarry on 

 the right of tiie route (probably at the base of the Brooksbottom series of 

 coals) caimot be here less tkan 1000 feet. The HasHngden fiags are then
