a single primitive species of dog, now destroyed, from which 
could have sprung all the varieties of domestic dogs known, by 
changes produced by the mere influence of climate and domesti-

30. Eartliquahe felt at Sea. — The East India Company’s ship 
Winchelsea, on the 10th February 1823, at 1** 10' p. m., in E. 
Long. 85“ 33', and N. Lat. 52°, experienced a shock similar to 
that of an earthquake. A tremulous motion of the vessel, as if 
it were passing over a coral rock, alarmed all on board, and this 
was accompanied with a loud rumbling noise, both of which con- 
tinued two or three minutes. As the ship was going only at two 
knots an hour, the Captain saw that there was no shoal, and 
considered the ship as out of soundings. There was no commo- 
tion on the sea, and the vessel was some hundred miles from 
land. This phenomenon has been ascribed to some volcanic 
eruption in one of the islands to the east of the Bay of Bengal.

31. Dr Hibherfs ‘‘ Philosophy of Apparitions.''] — Dr Hib- 
bert has just published a popular and highly interesting work, 
entitled “ Sketches of the Philosophy of Apparitions.” This 
production was suggested by the interest that his paper on 
the same subject excited, when read during the course of 
the last winter to the Royal Society of Edinburgh. As the 
volume only reached us as the present number was going 
to press, we have merely time to glance at the general plan 
of the work, which may perhaps best be described in Dr Hib- 
bert’s own words. ‘‘In the first place,” he observes, “ a gene- 
ral view is given of the particular morbid affections with which 
the production of phantasms is often connected. Apparitions 
are likewise considered as nothing more than ideas or the recol- 
lected images of the mind, which have been rendered more vi- 
vid than actual impressions.” In a second part of this work, 
he says, “ my object has been to point out, that in well-authenti- 
cated ghost stories of a supposed supernatural character, the ideas 
which are rendered ao unduly intense as to induce spectral illu-
