vation, but by like observations all along this coast, as far as the situation con- 

 tinues the same. 



At the top of the higher craggy cliff, at the point e, it is to be observed that, 

 as old men inform us, upwards of 40 years since, not so much as the top of 

 Tarlingham House could be discerned, neither from hence nor yet a good dis- 

 tance off at sea; but it discovered itself gradually, till at this day not only the 

 whole house, but a great tract of land below it, is plainly to be seen, as in the 

 line of sight egh. The tract of land is more in proportion than described in 

 the sketch, between the point at h and the house. In this there can be no 

 fallacy ; and we can ascribe it to nothing less than the sinking of the hills, for 

 their tops could never wear away considerably, being always covered with grass, 

 and never broken up by the plough or otherwise. These hills are all of chalk, 

 and have probably very large caverns within, springs of water always flowing 

 plentifully from the foot of them ; and on their tops frequent cracks have been 

 noticed. Whatever be the cause of it, it is not to be doubted but that these 

 hills are greatly sunk. And this sinking of the hills, the people at this place 

 believe, forces the cliffs and all the land forward into the sea. The cliffs consist 

 of large ragged sand-stones till we come to near a yard, at some places more, 

 of the bottom ; then we meet with what is called a slipe, i. e. a slippery sort of 

 clay always wet. On this slipe at the bottom, they suppose that the hard stony 

 land above slides forwards toward the sea, as a ship is launched upon tallowed 

 planks.

These observations chiefly relate to natural history; but there is nothing in 

 them of sufficient interest to entitle them to be reprinted. 



jin Account of the Mischiefs ensuing from swallowing the Stones of Bullace and 

 Sloes. By the Rev. IVm. Derham, F. R. S. N° 349, p. 484. 



Among the accounts which the Royal Society has had of the mischiefs 

 ensuing the swallowing of divers sorts of stones, I do not remember any case 

 wherein the lesser stones of fruits, such as sloes particularly and bullace, have 

 produced any dangerous symptoms, especially in the stomach alone. The larger 

 stones of prunes and plums, have produced very fatal effects; but the lesser 

 stones of sloes, cherries, &c. many swallow rather out of choice than with any 

 apprehensions of danger, thinking them useful in preventing a surfeit from the 

 fruit. But the following case will show the danger even of these lesser stones.
