in 1856, and at Meux’s Horseshoe Brewery twenty years later, 
utterly failed. The Lower Greensand thins out and disappears 
under London, as also do many other Secondary strata, so that 
a range of old Paleozoic rocks is brought within moderate distance 
of the surface. In Tottenham Court Road (Meux’s Brewery) 
Devonian rocks were struck at 1066 feet. It is quite within the 
range of geological probability that the coal measures pass beneath 
London, or its neighbourhood, at no very great depth. 
On Friday, February 5th, the Annual General Meeting was 
held under the presidency of Sir Samuel Wilks, Bt., F.R.S., the 
President. The Report of the Council was read and adopted. 
The President, Officers and Council were elected. 
The meeting was resolved into an Ordinary Meeting. The 
Rev. H. N. Hutchinson, B.A., F.G.S., gave a lecture entitled 
‘Extinct Monsters,’’ illustrated with models, with lantern photo- 
graphs of actual remains and of completed skeletons, and with 
lantern views by Mr. J. Smit of restorations from skeletons. 
Mr. Hutchinson first showed a restoration of a gigantic sea- 
_ scorpion (Eurypteus) of the Old Red Sandstone which was as much 
as six feet in length. He spoke of the great fish-lizards of the 
Jurassic period, the Ichthyosaurus with short neck, ponderous 
_ head and jaws, and large eyes with bony plates; and the 
Plesiosaurus with long neck and small head. These creatures 
measured some twenty or thirty feetin length. Their restorations 
were shown amid the contemporaneous plants and animals. 
There were shown representations of the Deinosaurs, the greatest 
reptiles whose remains have ever been found. They were terres- 
trial or in some cases amphibious. Of these was the Brontosaurus, 
discovered by Prof. Marsh in America, which measured 60 feet in 
length and was computed by the lecturer to have weighed as much 
as twenty tons. Its contemporaries in Europe were the Mega- 
losaurus, the Cetiosaurus, the Pterodactylus and the Iguanodon. 
Styosaurus and Triceratops are later American discoveries in~ 
strata of the period. The Pterodactyls shew an interesting approach 
among reptiles to the characters of birds. They had claws, beak- 
like jaws with teeth, feathered wings, and a pair of feathers at 
each vertebral joint of the tail. 
Mr. Hutchinson showed restorations of a marine serpentine 
reptile, Clidastes, of seventy feet in length, from the period of the 
chalk formation. The extinct mammals of tertiary and pleis- 
tocene times included the giant sloth Megatherium, the mastodon, 
the hairy mammoth, and the woolly rhinoceros. The last monster 
shown was the moa of New Zealand, an ostrich twelve feet high 
‘that has become extinct in historic times.
