near their close, and the eminent and experienced gentlemen who had 
conducted them were still warm in the harness, and ready to aid so 
distinguished a stranger in directing his inquiries, and in comparing 
notes with him regarding some of their conclusions; and it was much 
to their honor that they were willing to impart freely that knowledge 
for which they had toiled so long. In carefully perusing Mr. L.’s vol- 
umes, we have marked those parts which seemed to us of the greatest 
interest to the geologist, and regret that the limits of our present notice 
will not permit us to extract them—this we hope to do on a future 
occasion. 
We have said nothing of the views taken by our traveller of the 
social, moral, and political aspect of things here, because these matters 
belong rather to our literary neighbors. But we must say in one word, 
that we have never read the journal of an English tourist who has seen 
our institutions in so just a light, whose discriminations were more fair, 
and whose criticisms were better worth regarding. We were also 
equally instructed and gratified by remarks in chapter x11, on the state 
of education in the English universities—drawn out by what he saw 
_ of the general condition of educational institutions in this country. 
‘It has evidently been no part of his plan in composing these volumes, 
to acknowledge every act of civility or hospitality which he received 
while here; and in neglecting to do so, he has best consulted the. feel- 
ings of those most concerned, who opened their houses, not that they 
might appear on a tourist’s pages, but that they might enjoy the society 
of an intelligent foreigner and his lady, who, whatever instruction or 
pleasure they might receive, were sure to return at least a full equivalent. 
Now that Mr. Lyell has shown to his fellow laborers at home the 
interest and practicability of a geological and observational tour in 
North America, we trust that his example may be followed by some 
of his distinguished countrymen, whose lives and fortunes are so freely 
devoted to the cause of science. 
2. On the Liquefaction and Solidification of Bodies generally eu- 
isting as Gases; by MicuarL Farapay, (from the Phil. Trans., 
1845, p. 155.)—In this paper Mr. Faranpay has given greater extension 
to his former researches on this subject, (Phil. Trans., 1823, pp. 160 
—189,) has devised methods by which he has added six substances, 
usually gaseous, to the list of those which have been primarily obtained 
in the liquid state; and has. reduced seven, including ammonia, nitrous 
oxyd and sulphuretted hydrogen, into the solid form, beside revising and 
correcting previous results regarding the tension of vapor, Wc. 
The gases were, as in fomer experiments, subjected to considerable 
mechanical pressure and great cold by methods which we will briefly
