1716,) nourished with broth-glysters, in which a yolk, or 2 of eggs, and some- 

 times a glass of wine, were mixed, could also keep water in her stomach, 

 though no other fluid. An advantage which this patient was deprived of. 



From what has been related it appears, that this young lady had an abscess in 

 her stomach, which gradually ripened, and then broke, suppurated, digested, 

 and cicatrized, as all other abscesses do ; and that during this time, which was 

 near 3 months, she was almost all the while nourished solely by the mutton- 

 broth glysters. 



Account of an Irregular Tide in the River of Forth. By Mr. Edward Wright. 



N° 495, p. 412. 



There are in this river, at ebbing and flowing, certain irregular motions, not 

 to be found in any other river in Scotland, perhaps in Great Britain, or even in 

 all Europe, called by the common people leakies ; which means that when the 

 river is flowing, before high water, it intermits and ebbs for a considerable time, 

 after which it resumes its former course, and flows till high water ; and, vice 

 versa, in the ebbing, before low water, the river flows again for some time, and 

 then ebbs till low water. The leaky begins at a place called Queen's Ferry, 7 

 miles above Leith, at neap tide, and low water, and goes to the house of Maner, 

 which is about 25 miles above Queen's Ferry, that is, going by water; 

 though it be but 4 miles by land. This is noticed as he takes these windings to 

 be the cause of the leakies. At neap tide and high water, as also at spring tide 

 and low water, the leaky reaches as far as the sea fills, which is to the groves of 

 Craigforth, 19 miles above Maner house, and 3 above the town of Stirling. 

 At Queen's Ferry there are no leakies at neaps and springs at high water, nor in 

 the latter at low water ; they begin between Borrowstowness, a village about 7 

 miles above Queen's Ferry, and the mouth of a rivulet called Carron, 5 or 6 

 miles farther up the river than Borrowstowness. It is very remarkable, that in 

 the very lowest neaps, the leaky, after it has ebbed for some time, before high 

 water, makes up again, and will be 2 feet higher than the main tide. In the 

 beginning of the spring tides, it does not rise so high by a foot : at the dying of 

 the stream, it is often 2 feet higher than the main tide, which is to be under- 

 stood, before high water, when the leaky makes up again. At neap tide and 

 low water it will ebb 2 hours, and fill as much, and at full water ebb an hour, 

 and fill another. 



It is observable, that at full moon, there are no leakies, either at high or low 

 water, in the spring tides which are at that time, but in the neaps which fol- 

 low them, these motions are observable, as before described ; as also in the 

 spring tides, which happen on the change of the moon, there are leakies both
