SECT. XVI. 14. OF INSTINCT. 



keeping only his eyes above. My ingenious friend 

 Mr. Burdett, who favoured me with thefe accounts 

 at the time he was furveying the coafts, thinks the 

 commerce between the fexes takes place at this 

 time, and infpires the courage of the creature. 



5. The flioals of herrings, cod?, haddocks, and 

 other fifh, which approach our fliores at certain fea- 

 fons, and quit them at other feafons without leav- 

 ing one behind ; and the falmon, that periodically 

 frequent our rivers, evince, that there are vagrant 

 tribes of fifh, that perform as regular migrations as 

 the birds of paffage already mentioned. 



6. There is a cataracl on the river LLfFey in Ire- 

 land about nineteen feet high : here in the falmon

 or pinks, throw themfelves about twenty times their 

 own length out of the water, expecting to get into 

 the trough above. 



This evinces that the ftorgee, or attention of the 

 dam to provide for the offspring, is ftrongly everted 

 amongft the nations of fifh, where it would feera

 be fuppofed to attempt fo difficult and dangerous a 

 talk without being eonfcious of the purpofe or end 

 of their endeavours. 



It is further remarkable, that moft of the old fal-

 young (lioaU to attend them, yet that a few old ones
