[711] This view of the temple (substituted for one by A. de
Jorio, given in the earlier editions) has been reduced from
part of a beautiful colored drawing taken in 1836, with the
aid of the camera lucida, by Mr. l'Anson to illustrate a paper
by Mr. Babbage on the temple, read March, 1834, and published
in the Quart. Journ. of the Geol. Soc. of London, vol. iii.
1847.

[712] Mr. Babbage examined this spot in company with Sir
Edmund Head in June, 1828, and has shown me numerous specimens
of the shells collected there, and in the Temple of Serapis.

[713] This view is taken from Sir W. Hamilton, Campi Phlegraei,
plate 26.

[714] This spot here indicated on the summit of the cliff is
that from which Hamilton's view, plate 26, Campi Phlegraei
(reduced in fig. 88, p. 509) is taken, and on which, he says,
Cicero's villa, called the Academia, anciently stood.

[717] This appears from the measurement of Captain Basil Hall,
R. N., Proceedings of Geol. Soc., No. 38, p. 114; see also
Patchwork, by the same author, vol. iii. p. 158. The fact of
the three standing columns having been each formed out of a
single stone was first pointed out to me by Mr. James Hall,
and is important, as helping to explain why they were not
shaken down.
