4. " On the Foot-print of an Iguanodon, lately found at Hastings." 

 By A. Tylor, Esq., F.G.S. 



After alluding to former accounts of fossil foot-prints (and natural 

 casts of foot-prints) found in the cliffs near Hastings, and having 

 stated that Dr. Harwood in 1846 suspected these prints to have been 

 due to the Iguanodon, the author described a large three-toed foot- 

 print, 21 inches long, by 9\ in width, lately exposed by a fall at 

 East Cliff. A cast of this print was exhibited by Mr. C. J. Mann. 

 Mr. Tylor alluded to Professor Owen's figure of the bones of the 

 three-toed foot of an Iguanodon as illustrative of a foot capable of 

 producing such imprints as those referred to. The author then 

 showed, by a newly constructed section of the Hastings coast, that 

 the foot-prints occur in at least two zones of the Wealden beds, — 

 one of them being just above the chief sandstone (or Castle Sand- 

 rock) of Hastings, and dipping down to the west on the top of the 

 Bexhill cliffs ; the other zone being about 100 feet below, as already 

 pointed out by Mr. Beckles, near Lee Ness.

CONNEXION BETWEEN EARTHQUAKES AND MAGNETIC DISTURB- 

 ANCES. BY DR. J. LAMONT. 



ON the 26th of December 1861, at 8 o'clock in the morning, as I 

 was recording the position of the magnetic instruments (of which 

 there are six in the magnetic observatory — two for declination, two 

 for intensity, and two for inclination), I observed on all the instru- 

 ments an unusual disturbance, consisting in the fact that the position 

 rapidly and irregularly increased and then decreased by several divi- 

 sions, and at the same time a vibration in a vertical direction took 

 place. The vibration of the needles only lasted a short time ; but 

 the rapid alterations of the position continued, although diminish- 

 ing in intensity, till about half-past 8. A few days afterwards, news 

 arrived that at exactly the same time at which the above was ob- 

 served, an earthquake in several parts of Greece had produced great 

 devastation. 



Here is a new proof, not only that the concussions which an earth- 

 quake produces are felt at great distances, but that the forces which 

 produce the earthquake also modify the magnetism of the earth in a 

 certain degree. The modifications doubtless consist in the fact that 

 an earth-current is produced, which has also been so far confirmed, 

 in the above case, by the fact that the arrangements at this observa- 

 tory for observing the earth-current exhibited unusual activity at the 

 time mentioned. 



It is very remarkable that the earthquake which occurred in Greece 

 on the 18th of April 1842 produced a similar action, while hitherto 

 no action has been perceived from other earthquakes often at less 

 distance. — PoggendorfFs Annalen, January 1862.
