On a second visit, I observed it performed its flux and reflux in little more 

 than a minute's time, yet it would stand at its lowest ebb sometimes two or 

 three minutes ; so that it ebbed and flowed by my watch about l6 times in an 

 hour, and sometimes, I have been told, 20. As soon as the water in the well 

 began to rise, I saw a great many bubbles ascend from the bottom ; but when 

 the water began to fall, the bubbling immediately ceased. The whole country 

 adjacent is very hilly all along the coast; from Brixam to the top of the hill is 

 about a mile and a half, .the well is about halfway up the hill, which hereabout 

 is somewhat uneven a^ijd interrupted, and comes out at a small descent, yet 

 considerably higher than the surface of the sea. The water does not seem to 

 be impregnated with any mineral. Its taste is very soft and pleasant, has no 

 manner of roughness in it, and serves for all manner of uses to the country 

 people in their houses.

Of the true Cortex Winteranus,* and the Tree that bears it. By Hans Shane, 

 M.D.andS.R.S. N° 204, p. Q22. 



Capt. Winter, a commander of one of the ships which went out with Sir 

 Francis Drake, when he sailed round the world, brought into England from 

 the Straits of Magellan an aromatic bark, which had been very beneficial to his 

 crew, both used instead of other spices with their meat, and as a very powerful 

 medicine against the scurvy. Clusius, from some of those persons, gives a , 

 description and figure of it in his exotics, lib. 4, c. 1, p. 75, calling it cortex 

 Winteranus, from the commander of the ship, and the tree itself Magellanica 

 aromatica arbor. The writer of the journal of the Dutch ships, which went to 

 the Straits of Magellan about ISQQ, notices it as growing there, calling it, lauro 

 similis arbor licet procerior, cortice piperis modo acri, et mordenti. And Sebald 

 d« Wert, who was there, says, that both leaves and bark were used with their
