I. Tur Kesslerloch is a cave piercing a spur of the Jura, about a 
kilometre west of the railway-station at Thayingen (or Thaingen), 
in the Canton of Schaffhausen. It opens to the east on the level of 
the valley along which the railway passes, and to the south-west at 
about three métres higher level. Many similar, but smaller, caves 
are found in the neighbouring hills of upper white Jurassic limestone. 
Incited by the discoveries made in the many caves of Germany, 
Belgium, and France, the two masters of the High School of 
Thayingen, MM. Wepf and Merk, set to work examining this cave 
in the Christmas holidays of 1873-74. Having removed 1 to 13 
foot of fragments of limestone, they exposed a black layer, a foot 
or more thick, full of bones and horns and other remains. Beneath 
this they came upon a red bed, with black and brown patches in it, 
over 6 feet thick in one place (down to water), and crowded with 
small flint knives, cores, and flakes, broken marrow-bones, and other 
evidences of man’s early habitation. One of the most interesting 
specimens was found in the southern half of the cave, on the top of 
the red bed, about a métre below the surface, and consists of a piece 
of subcylindrical Reindeer-antler bearing an incised life-like outline 
of a Reindeer grazing. The deposits in the cave were horizontal ; 
but the floor of the cave was found to be much lower near the 
entrance than further back; and it is thought that the higher part 
was the habitation, and into the lower part the refuse bones, stones, 
&c. were flung by the old inhabitants. No definite succession of
