used for cutting towards one, as are adzes with us, and some of 
them to have been so shaped as to have been peculiarly well

to the article being detached. 
Evans in his Ancient Stone Implements describes hatchets, or 
broadaxes, like a certain class of tools found at Cissbury, in Eng- 
land, in certain pits in the chalk, that resemble our soapstone 
quarry tools in several particulars. Whilst Evans seems inclined, 
judging from the shapes of these tools, to attribute them to the 
Neolithic age, it is only, as he says, because of finding associated 
with them one or two ground celts that they were not considered 
Paleolithic. Judging from our present quarry experience, these 
tools, whilst so ancient in shape, appear to be among the most 
recent of the tools used during the stone age, which almost stag- 
gers one’s belief in paleolithic forms. It is very often most diffi- 
cult to describe stone implements, and I have seen but few palæo- 
liths, and therefore may be mistaken, but there is no doubt in my 
mind that implements identically similar in shape and material 
with cave or river-drift implements, are to be found on the surface 
and associated with polished articles of apparent recent date, and 
nowhere is this more strikingly illustrated than in the immediate 
vicinity of Washington city. These stones bear the same charac- 
teristics which we observe in implements found under circum- 
stances denoting a great age, but are in localities which lead us to 
consider them as modern.

ANNELID MESSMATES WITH A CORAL. 
BY J. WALTER FEWKES. 
THE Occurrenee of annelid tubes on the under surface of many 
Specimens of the well-known coral, Mycedium fragile Dana, 
Several localities, led me to suspect that the relationship of 
the wor ms which inhabit them to the coral, was that of com- 
Similar instances have been described in other genera 
authors who have mentioned the coral galls. A fact 
adds to the interest attached to this subject is, that in 
tall cases where the annelid is found associated with the 
"a, it has modified the general shape of the Mycedium to
