46 PHILOSOPHICAL TRANSACTIONS. [aNNO 17 13. 



The obstruction must have been in his kidneys, for he never had any inclination 

 to make water. The serous part of the blood, which should have been thrown 

 off by urine, was discharged by the coeliac and mesenteric arteries, by the 

 mediation of the glands, into the guts. He died of a fever. 



The second case, is an instance of old age in Martha Waterhouse and Hester 

 Jager, two sisters, both born in the township of North-Bierley. Martha, who 

 had been married, died in 171 1, in the 104th year of her age; and Hester this 

 present year 1713, in the 107th year of her age. I should not have taken 

 notice of their ages separately, it falling so far short of several instances which 

 have happened in this county ; but jointly I do not remember any that have 

 come up to them. 



From the longevity of human kind, I shall proceed to that of fish out of 

 their proper element. About 6 years since, great quantities of tench were 

 taken in a pond at Craven, and sent to the neighbouring markets. The fish 

 were taken on Monday towards night, and some brought to Bradford on 

 Tuesday about the same hour; and not being frequent in our markets, 6 of 

 them were sent hither to me on Wednesday. I not being at home, the basket 

 was set upon the kitchen table, not far from a good fire ; where it continued 

 till Thursday morning, the servants not knowing what was in it. On opening 

 the basket, and looking upon the fish, I thought the eyes of some of them 

 looked clear : I put two of them into a pail of water, and in less than 2 hours 

 time they swam very lively in the water. The remaining four showing no signs 

 of life, I put them into the same pail, and before night they all swam about 

 in it. 



Burbolts* being a fish not frequently met with in the southern rivers of 

 England, are often found in this county, especially in slow rivers and standing 

 waters, as in the river Foss in York, and also in the Derwent ; but in no place 

 more frequent, than in the fen ditches of the levels, about four miles from 

 Doncaster. 



I have several times seen plenty of small trouts caught in the mountainous 

 lakes of North Wales by angling ; and have, with no small admiration, con- 

 sidered the difficult access to these places, where a good footman can scarcely 

 climb up to them. That these lakes are yearly supplied from the brooks at the 

 bottom of the mountains I do not at all doubt, especially in spawning time, 

 when the trouts endeavour to surmount all difficulties, by passing up the small 

 rivulets, to deposit their spawn, for the preservation of their species, where it 

 is the most secure from the violence of other fishes, and there by accident fall
