116 Account of a Curious Phenomenon in Cephalonia. 



syphtn, it will be necessary to fasten the same handle to both 

 cocks, in such a way, that opening one shall shut the other, 

 but that the second one may also be shut separately. 



This syphon will run fully as fast as a straight pipe, but if 

 there is any level to spare between Prince's Street and the end 

 of the pipe rear Queen Street, the advantage of it will be ob- 

 tained by sinking B in Prince's Street straight down, and turn- 

 ing it up again towards H, so that the bend I of the pipe shall 

 be as low as the bend K in Queen Street. 



It is to be remembered that many of the wells of the New- 

 Town may be dried up by coming upon a spring in boring 

 through the hill, which is not at all unlikely. The practicabi- 

 lity of the scheme may be put to the test for less than L.3. — 

 I have the honour to be, &c.

On a Curious Phenomenon observed^ in the Island of Cephalonia, 

 and 071 the proximate cause of Earthquakes in the Ionian 

 Islands. By John Davy, M. D., F. R. S., Surgeon to the 

 Forces. In a Letter to Professor Forbes. 



Fort Pitt, Chatham, July 2. 1835. 



My Dear Sir, — As I fear it will not be in my power to at- 

 tend the meeting of the Association for the Advancement of 

 Science next month in Dublin *, allow me through you, to call 

 the attention of the physical class to a phenomena in Cephalo- 

 nia, of which I have lately been informed, of an extraordinary 

 and novel kind, as it appears to me, viz. the occurrence of streams 

 or currents of salt water /row the sea into the land. 



This curious fact was first mentioned to me, some months 

 ago, by my friend Dr White, Assistant Surgeon of the 2d Bat- 

 talion of the Rifle Brigade, in a letter which 1 received from 

 him when I was in Malta. I lost no time in replying to him, 

 and begged him to collect as much information as possible on 

 the subject, urging him at the same time to publish an account 



* It will be seen by the letter that this paper was intended to have been 

 communicated to the British Association ; but in consequence of Professor 

 Forbes's absence in Spain, was not received in time, and has subsequently been 

 read at the author's desire before the Royal Society of Edinburgh.
