in Wales too much north ; and hence, perhaps, the too great 
breadth given to the Briftol channel. This is, atleaft, the cafe 
with the town of Lantwit, which, as I have laid, is to the 
fouth ward of Frampton-houfe, the latitude of which is 
51° 25' 1 neverthelefs the belt and moft extenfive map * I 
have been able to procure gives the latitude of Lantwit 
51 0 29' 40", that is to fay 4' 39." N. of Frampton-houfe. 
There may very poffibly be particular charts of the Briftol 
channel more exaft: ; but it is not lefs true, that the common 
maps ought to be cleared of luch enormous errors. 
I determined the difference of meridians between Frampton- 
houfe and Greenwich by comparing four immerfions and four- 
teen emeriions of V- ’s firft and fecond fatellites tocorrefponding 
ones made in other obfervatories. The refult is as follows :
