372 Chronicles of Science. [July, 
ancient Briton,” so far as they can be inferred from the implements, 
ornaments, tombs, monuments, &c., which the researches of archee- 
ologists have brought to light. 
The same volume contains a description of a Romano-British 
mosaic pavement, representing Romulus and Remus, discovered at 
Aldborough (Isurium of the Romans), by Mr. Henry Ecroyd Smith. 
The ‘ Reliquary’ for April contains a short note by Mr F. C. 
Lukis, reminding us that the now well-known Stone Celt and Flint 
Arrow-head were formerly regarded in the north with considerable 
superstition, the latter being known as the ElfShot, while the 
larger examples were designated Elfin Darts. As usually happens 
in such cases, the same objects which in one district are highly 
prized as preventive of evil, are in others shunned as producers of 
misfortune. 
Mr. Peacock gives an account, in the same number, of the 
opening of a Celtic grave-mound, at Cleatham, Lincolnshire; and 
the editor, Mr. Llewellynn Jewitt, gives a description and figures 
of the urns. The excavation has been chiefly interesting as show- 
ing the manner in which these barrows were made. “ When a 
section of the hill was made, it became quite evident that the whole 
of this large hill had been carried where it was in baskets. Hach 
basket-load was distinctly visible.’ Mr. Peacock remarks that, 
although antiquaries have long known that this must have been the 
mode of accumulation, “ this is, perhaps, the first instance where 
ocular demonstration of the fact has been given.” 
Mr. T. M‘Kenny Hughes has commenced in the ‘Geological and 
Natural History Repertory and Journal of Pre-historic Archeology 
and Ethnology’ for May, a useful paper on flint implements, in 
which he endeavours to define the distinctions between the natural 
forms of flints and those which have been produced artificially. Pre- 
mising that the natural forms of flint are derived, Ist, from the 
original formation of flint in the chalk; 2nd, from fracture; and 
3rd, from weathering; the author describes the nature of these 
natural appearances, and insists on the truth of Mr. Evans’s canon, 
that the only kind of evidence of the human origin of manufactured 
forms which can be admitted is that of design shown in various ways. 
This paper will be specially useful as containing a descriptive cata- 
logue of a collection of implements in the Museum of Practical 
Geology, Jermyn Street, classified in series to illustrate the several 
categories to which various implements may be assigned. 
In the same number the editor, Mr. Mackie, describes and figures 
a very singular chipped flit in the shape of a flattened sphere, 
which was found at Willesden by Mr. Caspar Clarke. Unfortunately, 
the circumstances under which it occurred are not stated. Its use 
Mr. Mackie is uncertain about. From the drawings we should 
infer that it might have made a tolerable hammer.
