NATURE 
If 

p<esent president and committee, Prof. Liston was elected vice- 
yresident, and Mr. Andrew Taylor honorary secretary and 
treasurer. 
THE following is the programme of the lectures on the Ex- 
perimental and Natural Sciences in Trinity Term, in Trinity 
College, Dublin. Mineralogy, 11 A.M., on Mondays, Wednes- 
cays, and Fridays. Demonstrations in Organic Chemistry, 12 
Mondays, Wednesdays, and Fridays. Magnetism, 2 P.M., 
Mondays, Wednesdays, and Fridays. Comparative Anatomy, 
It A.M., Mondays, Wednesdays, and Fridays. Demonstrations 
in Botany, 11 A.M., Tuesdays, Thursdays, and Saturdays. 
Applied Geology, 1 p.M., Tuesdays, Thursdays, and Saturdays. 
THE grace for allowing French and German as an alternative 
for Greek, was submitted to the Senate of the University of 
Cambridge on Thursday last, and rejected by a majority of three 
only. The subject will doubtless be reopened, and probably 
some slight modification of the original scheme will ultimately 
be accepted. 
THE following gentlemen have been elected, by the Senate of 
the University of London, Examiners in Science and Medicine 
for the ensuing year :—Logic and Moral Philosophy: Prof. G. 
Croom Robertsonand Rev. John Venn. Political Economy : 
Prof. W. Stanley Jevons and Prof. T. E. Cliff Leslie. Mathe- 
matics and Natural Philosophy : Prof. H. J. S. Smith, F.R.S., 
and Prof. Sylvester, F.R.S. Experimental Philosophy : Prof. 
W. G. Adams and Prof. G. Carey Foster, F.R.S. Chemistry : 
Henry Debus, F.R.S., and Prof. Odling, F.R.S. Botany and 
Vegetable Physiology: Dr. J. D. Hooker, F.R.S., and Dr. 
Thos. Thomson, F.R.S. Geology and Palzontology: Prof. 
Duncan, F.R.S., and Prof. Morris. Practice of Medicine : 
John S. Bristowe, M.D., and Prof. J. Russell Reynolds, M.D., 
F.R.S. Surgery: Prof. John Birkett and Prof. John Marshall, 
F.R.S. Anatomy: ‘Prof. Geo. Viner Ellis and Prof. John 
Wood. Physiology, Comparative Anatomy, and Zoology : Prof. 
M. Foster, M.D., and H. Power. Obstetric Medicine: Rob. 
Barnes, M.D., and Prof. W. M. Graily Hewitt, M.D. Materia 
Medica and Pharmaceutical Chemistry : Thos. R. Fraser, M.D., 
and Prof. A. Baring Garrod, M.D., F.R.S. Forensic Medicine : 
E. Headlam Greenkow, M.D., F.R.S., and Thos. Stevenson, 
M.D. 
Mr. C. T. CLoucu, of Rugby School, has been elected to 
an exhibition at St. John’s College, Cambridge, of 50/7. per 
annum, for proficiency in Natural Science. There were ten 
candidates. 
SCIENCE appears to have penetrated even into the recesses of 
Christ’s Hospital. Since October 1869, there has been a Chemistry 
class of about fifty boys, in connection with St. Bartholomew’s 
Hospital. The work done is both practical and theoretical ; at the 
first, Dr. Matthiessen was the lecturer, and at his lamented death, 
Dr. H. E. Armstrong. Since Christmas the class has been 
under the care of Dr. W. T. Russell, F.C.S. For some weeks 
past, Prof. Tennant has been lecturing on Mineralogy, and next 
week commences on Geology. This class is very well attended. 
There has been established a permanent class for Natural 
Philosophy, under the care of Mr. James Noon, B.A. We believe 
also that those boys who are intended for the Navy are in- 
structed in theoretical and practical Astronomy. There have 
been wishes expressed for a Museum, and numerous speci- 
mens are constantly brought to Prof. Tennant for informa- 
tion. Itis much to be wished also that some sort of a Natural 
History Society might be established, notwithstanding the city-site 
of the Hospital. 
- WE continue to receive intelligence from the French Academy, 
and are in a position to give the full list of members who were 


present at the sitting on the 21st April, eighteen in number, viz., 
three astronomers, Yvon Villareau, Mathieu, and Langier ; 
one mathematiciau, Chasles; one physicist, Jamin, three chemists, 
Chevreul, Payer, Peligot ; one mechanician, Ameral Paris; and 
the others medical men or naturalists, Milne-Edwards, Blanchard, 
Robin, Trécul, Bienaymé, Duchartre, and Quatrefages. M. Egger, 
of the Academy of Inscriptions, sat with his colleagues, and M. 
Simon Newcomb, the American astronomer, sat at the place 
allotted to foreign learned men. 
THE seventh part of the illustrated work on the butterflies of 
North America, by Mr. Wm. H. Edwards, has just been pub- 
lished, containing numerous well-engraved and coloured plates of 
butterflies. 
Tue Commune has its own balloons, twelve in number, but 
they are kept apart for the private use of members when the final 
exit shall take place. One was sent up into the air, as it was said 
in the political newspapers for carrying away the masonic pro- 
clamation, but it was a little one without aéronaut. 
THE Gardener's Chronicle for last Saturday prints an interest- 
ing letter from Dr. Hooker, dated Tetuan, April 12. In the 
journey from Tangier to Tetuan, Dr. Hooker notices that the 
general features of the flora of the low grounds and moderate 
hills in that part of North Morocco coincide with those of South- 
western Spain. Whole tracts are covered with masses of broom, 
so that the hills precisely resemble those of Scotland or Jersey. 
The previous day a guard had been obtained in order to ascend 
Beni-Hosmar, which mountain had only been visited previously 
by one botanist, Mr. Webb, some forty years since. The party 
ascended to 3,500 feet, and obtained a superb view across the 
Mediterranean to the Spanish coast, and south to the snowy 
crest of Beni-Hassan. It is a splendid rugged mass of limestone 
peaks, separated by very steep narrow-floored valleys, the flanks 
of which are crested with rifted white precipices. The whole 
is clothed with stunted shrubs up to 3,000 feet. They found 
some rare, and some probably new plants, but at a height of 
3,400 feet no signs of a sub-aipine flora. The party did not 
succeed in reaching the summit. 
THE principal object of interest at the soz of the Linnean 
Society on the 26th ult., was again Mr. Wilson Saunders’s col- 
lection of mimetic plants, which was even more remarkable than 
last year. The following is a list of the pairs exhibited :
