oppofite to it; and which alfol doubt not but may be 
found on the other Coafts of England, efpecially the 
South and Weftern parts, (in which I am almoft aflured 
I have formerly feen them, though then unknown to 
me,) where there are Rocks and great Pebbles, and 
where the Tides run not too ftrong. Which difcovery 
I do not pretend to be fo made by me, as having no hint 
of it before 5 for in ^?So^^r,i6 84,there were two Ladies ac
