Herr Woldrich describes the surface markings of speci- 
mens in his own large collection, and points out the re- 
semblance between certain of these Bohemian examples 
and the peculiar obsidian-bombs from Australia, described 
by Stelzner. Some of the Bohemian occurrences show, 
in fact, a hollow, bomb-like form. A fragment of such a 
specimen is represented in Fig. 8a. Figs. 4 and 6, 
types of sculpture, Fig. 4 exhibiting “finger impressions,” 
and Fig. 6 a network of furrows, having in part a rough 
radial arrangement. The moldavite found both in 
northern and southern Bohemia occurs in sandy de- 
posits which are regarded as belonging to either late 
Tertiary or early Diluvial time. Herr Woldrich con- 
siders that the known facts relating to moldavite and its 
distribution speak in favour of its extra-terrestrial origin, 
but that it is only known to occur in sandy deposits, 
whether in Europe or on other parts of the earth’s surface, 
he regards as a striking circumstance. 
NOTES. 
AT a meeting of the Glasgow University Court held on the | 
13th inst., Principal Story presiding, a petition for leave to 
retire from the chair of Natural Philosophy was presented from 
Lord Kelvin. The Court granted the leave asked, and accepted 
Lord Kelvin’s resignation with deep regret. A remit was made 
to the Principal to prepare a minute to be signed by all the | 
members of the Court, expressing their sense of the great loss 
that the University is now to sustain. Lord Kelvin has 
occupied the chair for fifty-three years. 
Dr. P. F. RAymonp, the successor of Prof. Charcot in the 
chair of Nervous Diseases at the Saltpétriére, has been elected 
a member of the Paris Academy of Medicine.

| THe death is announced in the d4¢henaeum of Dr. Eugen 
Ritter von Lommel, Rector of the University and a member of 
the Academy of Sciences of Munich. He was the author of 
several works, including ‘‘ Das Wesen des Lichts,” ‘* Wind und

THE negotiations which for some time past have been carried 
photographed in natural size, show two characteristic | 0n between the Royal Geographical Society and the University 
of Oxford with a view to the establishment at Oxford of a fully- 
equipped school or institute of geography, for the use, not only 
of Oxford graduates and undergraduates, but of others who 
desire to avail themselves of such an opportunity, have come 
to a satisfactory conclusion, and the school will begin operations 
in October next, under the direction of Mr. H. J. Mackinder. 
The Royal Geographical Society is to contribute 400/, annually 
for five years out of the 800/. required, and the school will be 
under the supervision of'a joint committee of representatives of 
the Society and the University. At a recent meeting of the 
| committee, the staff was appointed, Mr. Mackinder being the 
| head of the school, and dealing specially with historical 
| geography ; Mr. A. J. Herbertson has been appointed assistant 
to the Reader, and will deal with physical geography, carto- 
| graphy, and surveying; Mr. H. N. Dickson has been ap- 
| pointed Lecturer on Physical Geography; and Mr. G. B. 
Grundy will in 1899-1900 lecture on ancient geography. The 
| work of the school will include a course of systematic instruc- 
tion primarily intended for graduates and other advanced 
students, with classes, demonstrations, and practical work in 
physical geography, cartography, and surveying. Courses of 
lectures will also be given with special reference to the his- 
torical and scientific teaching of the University The work 
will be carried on for five days each week during term. The 
lecture-room and laboratory will be in the Old Ashmolean
