near the city of Celsense, in Phrygia, which throws np masses 
of stone. 'Not far from it are two other springs, called Clseon^ 
and Gelon by the Greeks, from the effects which they re- 
spectively produce. At Cyzicus is a fountain known as that 
of Cupido, the waters of which, Mucianus believes,^^ cure those 
who drink thereof of love. 
CHAP. 17. — ^WATEKS WHICH PKESEEVE THEIR WARMTH FOR THREE 
DAYS. 
At Crannon^^ there are certain hot springs, though not at 
boiling heat, the water of which, mixed with wine, preserves 
it warm in the vessels for a period of three days. The same is 
the case, too, with the springs of Mattiacum^^ in Germany, 
beyond the river Ehenus, the water of which retains its boil- 
ing heat three days. The margin of these springs is covered 
with pumice, formed by the action of the water. 
CHAP. 18. OTHER MARVELLOUS FACTS CONNECTED WITH WATER. 
WATERS IN WHICH EVERYTHING WILL SINK. WATERS IN WHICH 
NOTHING WILL SINK, 
If any of the above-mentioned facts have the appearance 
of being incredible to a person, I would have him know that 
there is no department of Nature which presents greater mar- 
vels than this, independently of the numerous peculiarities 
which have been already mentioned^* in an earlier part of this 
work, Ctesias informs us that, in India, there is a lake of 
standing water, upon which nothing^^ will float, every object 
instantly sinking to the bottom. Cselius says that in the 
waters of Lake Avernus,^^ in our own part of the world, the 
very leaves of the trees even will sink ; and, according to 
Yarro, these waters are fatal to such birds as fly towards them. 
On the other hand, again, in the waters of Lake Apuscida- 
mus/^ in Africa, nothing will sink ; the same, too, Apion tells 
From KXaUiv, to weep," and ya\<^Vj "to laugh." 
His credulity, v/e have seen already, was pretty extensive.

Sotion, professing to quote from Ctesias, says that it rejected everything 
placed on its waters, and liurled it back upon dry land.
