originals of which are in the collections of Dr. Uhlmann and 
the late M. Troyon ; the latter collection is now preserved in 
the Public Museum at Lausanne. 
A 32. 
Nos. I and 13 are pieces of stone, showing marks of sawing. 
The other specimens in this Case are stone hatchets from Wan- 
gen, some of which, such as Nos. 6 and 8, appear to have been 
blunted by use. 
The mode by which stone hatchets were made by the lake- 
dwellers has been described by the late M. Troyon. The block 
of stone was in the first place reduced to a suitable size with 
a hammer stone ; the outline was marked out by grooves 
worked to a depth sufficient to weaken the stone, and the pro- 
jecting portions were then removed by a skilful blow with a 
hammer, after which the implement was smoothed and sharpened 
upon a fiat grinding stone. The specimens Nos. i and 13, in 
this Case, show marks of sawing, and many of the hatchets 
have similar marks half way through their thickness. The 
lake-dwellers worked bone in a similar manner. See No. 23, 
Case D 20. 
A 33 
Contains a series of stone hatchets. Nos. i to 11 are from 
Wangen ; Nos. 12 to 19 from Moosseedorf ; Nos. 20 and 21 
from 'Concise ; Nos. 22 to 26 from Lausanne; and Nos. 27 to 
41 from Robenhausen. 
D 20 
Contains portions of the piles from Moosseedorf, Nos. 32 to 34. 
The head of a pile, with a mortise cut in it to receive the timber 
of the platform, found at Robenhausen, has been figured by Mr. 
Lee. Similar heads of piles were found at Niederwyl. Speci- 
mens of various kinds of wood, Nqs. 35 to 39, are shown from 
Moosseedorf; Nos. 16 to 20, and 24 to 30, are pieces of stag's 
horn partly worked into mounts for hatchets ; No. 27 is made 
into a chisel ; No. 3 1 is a portion of a shed antler of red deer, 
showing marks of hacking with some rude tool, probably a stone 
hatchet; Nos 21 and 23 are fragments of bone, bearing marks of 
sawing and human workmanship; Nos. 9 to 15, and 40 to 53, are 
fragments of pottery from Moosseedorf, Robenhausen, and 
Wangen. 
The potter's wheel was probably unknown to the lake- 
dwellers of the Stone period ; the baking of the pottery is very
