From Bishop Sprat's account of oysters given in 

 the ' History of the Royal Society,' republished in 

 Latin by Dr. Lister in his ' Hist. An. Angl.,' copied 

 from Dale's ' History of Harwich ' by Pennant in his 

 * British Zoology,' and since by Prof. Forbes, I shall 

 only quote, to show that, probably from the beds 

 having been over -fished since the bishop's time, the 

 oysters now spawn much later than they did formerly. 

 This subject will be referred to again in the course of
