Earthquakes and their connection with Meteorological Phenomena. 
A letter addressed from M. Julius Schmidt, astronomer at the 
observatory, at Athens, to Director Haidinger, gives details of an 
earthquake felt there on July 4th, 1860, at half-past six p.m.. At 
the same time a violent thunderstorm was rising above Mount 
Hymettus, and low clouds of a quite uncommon form began to cover 
the top of the mountains. M. Jul. Schmidt has stated the coinci- 
dence between atmospheric phenomena and subterraneous commotions 
of a probably local nature being circumscribed within the geological 
system of Mount Hymettus. The observations of this able astro- 
nomer have given the following results : 
1852. July 16th, evening : commotion ; strong thunderstorm on 
Mount Hymettus ; abundant rain ; clouds of striking form on the 
mountains. 
1860. Feb. 6th, morning : commotion; thunder- stroke on Mount 
Hymettus ; clouds of uncommon form on this mountain, persisting 
during half an hour. 
1860. July 4th, evening : commotion ; violent thunderstorm on 
Mount Hymettus ; clouds of fantastic forms. 
At the date of this letter (July 7th) M. Schmidt was specially 
employed in observing the new comet. During May 1860 he joined 
Prof. linger of Vienna in a tour through Euboea (where he mea- 
sured Mount Delph, or Diphis, one thousand seven hundred metres 
in height, or about five thousand four hundred feet, Boeotia, and 
back to Athens through Eleusis. Interesting facts concerning the 
topography and hydrogi^aphy of Boeotia were the result of this 
excursion. On July 9th M. Schmidt was to set out for Egina for 
two days. The Greek government has directed the provincial 
authorities to collect evidences concerning earthquakes, and to trans- 
mit them to the observatory at Athens.

" On the Structure of the North-west Highlands, and the relations of the 
Gneiss, Red Sandstone, and Quartzite of Sutherland and Koss-shii-e." By 
Professor James Nicol, F.G.S. 
The author first referred to his paper in the Quart. Journ. Geol. Soc., vol. 
xiii., pp. 17, &c., in which the order of the red sandstone on gneiss, and of 
quartzite and limestone on the sandstone was described, and in which the rela- 
tion of the eastern gneiss or mica-schist to the quartzite was stated to be 
somewhat obscure on account of the presence of intrusive rocks and other 
marks of disturbance. Having examined the country four times, with the view 
of setthng some of the doubtful points in the sections, the author now offered
