Bath, as plainly to prove, that the discharge of both choler and stone proceeded 

 from the motion of the coach. 



That his deliverance from the jaundice, commenced from the expulsion of 

 this stone: for soon after that, the colour of the skin and urine, indeed all the 

 bad symptoms vanished ; and in a very little time, weakness only excepted, he 

 recovered. 



All these circumstances put together, make a considerable argument, that 

 the orifice of the ductus communis (how strait and how strong soever) was, 

 in this gentleman, so far dilated, as to give way to the stone, here described ; 

 that is, dilated to a circle, -rV o^ ^^ i"ch in diameter, in circumference one 

 whole inch and -|-*. 



The jaundice is often observed to be a most stubborn distemper, not easily 

 yielding to our most probable methods; and often to none at all. Riverius 

 positively affirms, that when it proceeds from a stone, obstructing the current 

 of the choler, it is incurable: urging this reason for his opinion ; calculus, cum 

 dissolvi non possit, morbum facit incurabilem. Capite de ictero. When the 

 jaundice is thus difficult of cure, especially when there is a probability (whether 

 from a pain fixed in or near the region of the liver, or from any good argument 

 whatever) that it arises from the cause now mentioned ; it may be adviseable to 

 take exercise on horseback, in a coach, or any such way, as shall be likely to 

 dislodge the stone, and bring it offi But to make this exercise effectual, it 

 ought to be as violent, as the patient can well bear ; and in such manner, as 

 may, by much agitation of the body, be most conducive to the cure. 



A further jiccount of an Eruption of Waters in Craven. By Mr. Ralph 

 Thoresby, F.R.S. N° 306, p. 2236. 

 In Phil. Trans. N° 245, -j- is some account of an extraordinary eruption of 

 water in Craven. I was lately inquiring concerning it, and am not only fully 

 satisfied of the truth of what Mr. Pollard there affirms, but also that, as he 

 conjectures, a great part of the land is not to this day recovered from the 

 sand and stones, though a great number of people were employed about it. 

 On the opening of the rock, at the foot of which the town of Starbotham 

 stands, the water gushed out in so vast a quantity, as if it would have swept 

 away the whole town : the waves came rolling down one upon another. Several 

 houses were quite ruined ; and others wrecked up to the chamber windows ; 



* There appears to be some mistake in one of these numbers : for -rV o^ ^^ '"^^ diameter will 

 answer to 2-j^ inches in circumference } and 1| inch circumference would answer to but about 

 5^ tenths.
