RECIPROCATING SPRINGS. 
fountain of Jupiter in Dodona, we know too little of it to 
judge of its true character ; and it is not improbable but future 
observations will add Pliny’s Well to the class of irregular 
reciprocators. 
It may be reasonably supposed, that since I have endeavoured 
to confine the established theory of reciprocation to one or two 
springs at most, a new explanation will be offered on my part, 
comprehending the phenomena of those wells, which ebb 
and flow according to no certain rule. Before I make this 
attempt, it will be proper to give a more circumstantial account 
Account of the of the appearances exhibited by the well at Giggles wick, than 
SSgfeswfck** ^ as ^i^ ierto been published. I neglected, when in the country, 
Well. to preserve a correct register of its fluctuations, and committed 
no other observations to writing, except those which appear 
in a former part of this essay. This omission, however, has 
been fully supplied by Mr. John Swajnston, of Kendal; to 
whom I formerly communicated my imperfect remarks on this 
well, requesting him at the same time to note down a series 
of its operations, at some convenient opportunity. This request 
was complied with by my friend ; who has digested his obser- 
vations in the following table, which merits the esteem of the 
naturalist, as being a faithful history of this singular foun- 
tain.
