also been discovered. These include the bear, wolf, fox, hysena, 
cave-lion, bison, Irish elk, mnsk-ox, elephant (mammoth), 
rhinoceros,* hippopotamus, beaver, &c. One of the most noted 
localities for mammalian remains is Ilford, and this is in a great 
measure due to the energy of Sir A. Brady, who has devoted 
much time and expense to their collection and preservation. 
There are good grounds for believing that man co-existed 
with these animals. The discovery of flint implements, the 
works of man, in our valley-gravels, places his antiquity beyond 
a doubt. 
The earliest record (before 1715) of the discovery of any 
implement is recorded in the Sloane Catalogue (British 
Museum). “ No. 246. A British Weapon found, with elephant’s 
tooth, opposite to Black Mary’s, near Grrayes Inn Lane. It is 
a large black flint shaped into the figure of a spear’s point.” 
In 1868 an implement was found by Mr. Norman Evans in 
the brick-earth of Highbury New Park; and in 1871 Colonel 
Lane Fox found an implement, eight inches long, at Acton, 
beneath thirteen feet of sand and gravel. Other implements 
were found at Ealing, and all, according to Mr. Evans, were of 
well-marked palaeolithic types. Implements have also been 
found at Hackney Down, Hammersmith, Battersea, Hounslow 
Heath, &c.f 
In regard to the antiquity of man, which is indicated by the 
discovery of these and other evidences of his workmanship, we 
may quote the words of Mr. Evans. 
66 When we remember that the traditions of the mighty and 
historic city now extending across the valley of the Thames do 
not carry us back even to the close of that period of many 
centuries when a bronze-using people occupied this island ; 
when we bear in mind that beyond that period lies another of 
probably far longer duration, when our barbaric predecessors 
sometimes polished their stone implements, but were still un- 
acquainted with the use of metallic tools ; when to the historic, 
bronze, and neolithic (newer stone) ages, we mentally add 
that long series of years which must have been required for the 
old fauna, with the mammoth and rhinoceros, and other to us 
strange and unaccustomed forms, to be supplanted by a group 
of animals more closely resembling those of the present day ; 
and when, remembering all this, we realize the fact that all 
these vast periods of years have intervened since the completion
