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 has found, also, 
trifids of the usual size in the Wealden 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 the 
Wealden. 
9. " Geological Notes on Zanzibar." By E-ichard 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-limestone, sandstone, yellow shale, and sandstone with 
plant-remains. The mountain Kilimanjaro is formed chiefly of volcanic 
rocks. While and altered sandstones, with easterly dip, are met with also 
in the Massai Plain. 
10. " On a Section at Junction-road, Leith." By W. 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 Eoman occupation, not only have mediaeval pottery and 
tobacco-pipes been found in the pottery-bearing deposit described by Mr. 
Geikie, but a mediaeval jar has been met with in tile saud beneath. The 
so-called '•Homan" pottery was stated by the author to be of mediseval 
age, on the independent authority of Messrs. Birch and Franks, of the 
British Museum ; and he believes that the beds in question are mainly 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. 
Steaming between Mangalore and Cananore, on the west coast of India, 
the author found that for some time after the south-west monsoon 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 of Elephas Melitensis and Myoxus Melitensis, obtained from 
bone-caves in Malta by Captain Spratt, were exhibited by Dr. H. Fal- 
coner. 
Manchester Geological Society. — May 27. — Mr. Binney read "An 
Account of the Excursion to Todmorden." On reaching Todmordeu, the 
party proceeded along that beautiful valley to Gauxholme, over strata 
belonging to the lower portions of the millstone grit. At the entrance of 
Dulesgate strong gritstone rock was seen dipping at a considerable angle 
N.W., and exhibiting shakes and faults. On Pendle Hill, beyond Burnley, 
and at Tintvvistle, near Glossop, are two natural sections which can be 
pretty well measured, especially the latter, where, between Rhodes Wood 
Quarry in the valley, and the thick bed of rock at Tintwistle Nar on the 
hill, are from 700 to 800 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 1200 feet in thickness. 
These beds probably attain their greatest developmeat in Lancashire, 
Yorkshire, and Cheshire. Eeturning again to the Gauxholme Eork, a small 
seam of coal was observed, and at a further distance up tlie valley another 
bed of a few inches. From the entrance of the valley to the quarry on 
the right of the route (probably at the base of the Brooksbottom series of 
coals) cannot be here less than 1000 feet. The Haslingdcn flags are then
