294 on the generation of. “A bes. Ott. dr 
rally see. During the monsoon, the torrents of rain 
are so heavy, that there is a stream of running water 
over the whole face of the country; the grafs, that 
then grows lusuriantly, keeps up an inch or more of 
running water on the highest grounds. From the 
eagernefs with which I have seen fith endeavour to 
ascend running streams, and from having frequently 
‘seen them make their way through wet grafs, I am 
convinced that all the fifh of any magnitude, that ap- 
pear at the commencement of the rains, come from 
the sea by the rivers, that are soon filled; for none I 
believe are correct enough as to time, to say that 
thete was not water running into the sea, by which 
they might ascend; and that it is only after having 
got to the highest grounds that the fifh are caught 
in nets plated at the bottom of the descending 
streams. 
The natives believe that these immense quantities 
of fifh are produced from the eggs of fith deposited in 
the mad; and they afsert that they mud of any tank, if 
put in water, will produce fifh. Some mud that has 
been brought me gives great probability to this opi- 
nion ; for it is full of eggs.. I have forwarded a lit. 
tle to your correspondent ia London. They say that 
these eggs are not destroyed although exposed to the 
burning rays of thé sun for months.* I am trying 
some just now taken froma tank that has been dry 
% This is a very curious fact, and deserves to be ascertained with 
care. The mud is not yet come to hand, but when it does experiments 
thall be tried with it. In the mean while we are to hope that our 
Correspondents in India will prosecute this subject. Edit.
