A limited number of fellowships for post-graduates 
in chemistry who are desirous of adopting an industrial 
career are being offered by the Salters’ Institute of 
Industrial Chemistry to become operative in October 
next. The fellowships are of the annual value of from 
2501. to 300/. each. Applications, with full particulars

UNDER the auspices of the Pontificia cadet 
Romana dei Nuovi Lincei, a number of public lectures 
on subjects of scientific importance has been given 
recently in Rome. On April 26 and 27 Prof. C. J. 
de la Vallée Poussin, of the University of Louvain, 
lectured on functions of a real variable ; on April 28, 
Prof. G. Gianfranceschi, of Rome, dealt with the 
structure of the atom; and on April 30, Prof. G. 
- Boccardi, of the University of Turin, discussed the 

position of research on the variation of latitude. A 
lecture in commemoration of Louis Pasteur was 
delivered on May 2 by Prof. A. Anile, of the University 
of Naples, who dealt with the life and work of 
Pasteur. The addresses are to be printed and 
published by the Academy in due course. 
Tue Société Frangaise de Physique, the head- 
quarters of which are at 44 Rue de Rennes, Paris, 
was founded in 1873. There are now more than L100 
members, including 250 foreign members. Meetings 
are held twice monthly, and the transactions are 
published in a Bulletin. In addition to the Bulletin, 
members receive every month the Journal de Physique 
et le Radium, which publishes original communications, 
particularly on subjects dealt with at the meetings 
of the Society, and includes a review of a large number 
of French and foreign periodicals. Persons desirous 
of becoming members should send to the president 
a written application, supported by the recommenda- 
tion of two members. The yearly subscription for 
foreign members is 65 francs, with an entrance fee of 
to francs.

In connexion with the visit of H.R.H. the Prince 
of Wales to the East Hecla Works of Messrs. Had- 
fields, Ltd., to which reference was made last weely 
Pp. 759, we have received a description of the equip- 
ment of the works, including the research laboratories, 
which are provided with a very extensive range of 
instruments for the study and investigation of steels. 
In addition to the mechanical laboratories, in which 
alternating and impact tests are conducted as well 
as the older tests, there is a thorough equipment 
for the standardisation of pyrometers, whether. 
thermo-electric, resistance, optical, or radiation. 
The apparatus in this section includes a Harker 
furnace for very high temperatures. Electrical and 
magnetic testing instruments are also included, in 
addition to the usual micrographic equipment. A 
feature of the department is the collection of specimens 
illustrating the researches which led to the discovery 
by Sir Robert Hadfield of manganese steel and of 
low hysteresis steel. Collections illustrating the early 
history of metallurgy were also exhibited on this 
occasion. 
Tue Board of Managers of the Washington Academy 
of Sciences has elected the following honorary foreign 
members in recognition of their prominence in their 
respective fields and their intimate connexion with 
scientific work in Washington: Prof. L. Manouvrier, 
Paris, for his work in anthropology; Dr. C. F. A. 
Christensen, director of Universitetets Botaniske 
Museum, Copenhagen, for his services to systematic 
botany, particularly his monographic studies of 
tropical American ferns of the tribe Dryopterideae ; 
Dr. Paul Marchal, French Ministry of Agriculture, for 
his investigations in biological problems and their 
relation to agriculture, and especially for his research 
work in polyembryony ; Mr. E. C. Andrews, Govern- 
ment geologist of New South Wales, for his work in 
geology, particularly in the fields of origin of coral 
reefs, physiography, origin of the Australian flora, 
mountain formation, and origin of metalliferous 
deposits ; Sir Ernest Rutherford, for his distinguished 
work in chemistry; Prof. F. Omori, professor of 
seismology, Imperial University, Tokyo, for his out- 
standing work in seismology; Prof. G. Stefanini, 
Florence, for his investigations in paleontology and 
stratigraphy, especially the tertiary formations of 
Italy and echinoids in general ; and Prof. Max Weber, 
University of Amsterdam, for his work in zoology. 
In the Journal of the Franklin Institute for May, 
General Squier describes a method of transmitting 
the telegraph alphabet which can be applied to radio 
communication, telegraph lines, and submarine cables. 
Owing to the rapid expansion of radio telephony and 
telegraphy the problem of interference, both natural 
and artificial, has become one the solution of which 
must shortly become imperative. As there are only 
a limited number of lanes through the ether their 
conservation is of international importance. Radio 
waves are used very widely in navigation and for 
radio beacons. In addition, we seem to be on the 
threshold of another great development—“ photo- 
broadcasting,’’ which will require and demand still 
more ether channels to serve the public of the near
