 The distribution assigned to some of the lines in the above 

 tables is subject to correction. The intensities arc deduced 

 from an examination of photographs, taken with verj- varietl ex- 

 ix>sures : some having been e.xiiosed long enough to bring out the 

 fainter lines, and some a short time to give details of structure 

 in the stronger lines. Unless all the photographs have been 

 ex|X)se<I for the same time, there is a liability of the relative 

 intensities of lines in one picture not being the same as those in 

 another picture. Judgment is needed in deciding whether a line 

 is to have an intensity of 7 or 8 assigned to it ; and as in the 

 tables I have not inchuletl lines below intensity 8, it might 

 happen that another series of photographs with independent 

 measurements of intensities would in some degree alter the above 

 arrangement. 



In the following table I have given a list of lines which arc 

 probably identical w ith lines observed in the chromosphere and

Mayor of San Francisco, has just offered the State University 

 R<^ents thirteen acres of land within the city limits, on which 

 to erect buildings for the afiiliatod colleges of the University. 

 In addition to this, he will deed to the Trustee of the city 

 thirteen acres adjoining, as a site for the Sutro library of over 

 200,000 volumes. The gift is valued at ;^300,ooo, and will be 

 worth /^400,ooo when the contemplated improvements are 

 made. 



The Clothworkers' Exhibition, awarded by the Oxford and 

 Cambridge Schools Examination Board to the best candidate in 

 physical science at the examination held for higher certificates, 

 has been gained by T. W. F.igan, Denstone College, StaH'ord- 

 shire. The exhibition, which is of the value of ;^52 lat. a year, 

 is tenable for three years by the holder as a non-collegiate student 

 at either Oxford or Cambridge. 



Mr. W. M. G.vrdner, .\ssistant Lecturer in Dyeing in the 

 Yorkshire College, Leeds, has been appointed Head Master of 

 the Chemistry and Dyeing Department of the Bradford 

 Technical College. 



The Calendar of the Durh.im Collegeof Science, Newcastle- 

 upon Tyne, for the session 1895-96 hsisjust been publisheil, and 

 also separate prospectuses of the day and evening cKtsses. 



Sir \. Roi.LiT askeil the First Lord of the Treasurj- on 

 Tuesday whether the Government intended, and when, to |)ro- 

 pose legisLition in pursuance of the reix)rt of the Gresham 

 Commission or the University of London. In reply, .Mr. 

 Balfour .said that legislation will l)e ini|K)ssible on the subject in 

 the course of the present Session, and he was unable to say what 

 action will be taken by the Government. 



The operations of the City and Guilds of London Institute 

 are divide<l broadly into two branches, viz. the educational 

 work of three London Colleges, and of the Technological 

 Examinations. The new edition of the prograntme of the latter, 

 including regulations for the registration and inspection of classes 

 in technology and manual tiaining, has come to hand. It is 

 more bulky that any of the previous programmes of the examina- 

 tions, which fact may be taken as an indication that the Institute 

 is grtiwing with the extension of tccltnical e<Uication. The 

 technical subjects in which examinations are held now number 

 sixty-three. A practical examination for "electric wircmcn" 

 has been added, and a corresponding addition has been made to 

 the syllabus for the preliminary examination in "lectric lighting. 

 The syllabuses of several other subjects have been modified, and 

 that in wood-work has been rewritten. 



The forty-second Report of the Department of Science and 

 .Art has just been received. \ noteworthy point shown by the 

 statistics contained in it is the diminutiim in the number of 

 science schools, clas,ses, and students under instruction, brought 

 about by the abolition of grants for secimd-class (la-sses in the 

 Elementary Stages of Science subjects. As compared with the 

 previous year, the nundjer t)f scIuk>Is in 1894 hail <iecreasetl by 

 152 — from 2754 to 2602 ; the number of pupils had decreased by 

 about 10,000— from 193,431 to 183,120; and the luimber of 

 classes in <lifl'erent branches of science had decreased by <>o8 from 

 10,341 to 9433. This diminution is attributed to the changes In 

 payments on results, "anil also probably to the opening of 

 numerous technical cbsses by the local authorities in diti'irent 

 parts of the country, which have drawn away the students from 

 the classes in (nire science. The decrease in the number of 

 schools and cl.asses is owing partly to the same cause, and larlly 

 to the amalgamation of smaller S(-hools,or to their absr>rplion in 

 the more pros[«;rous and better .supporteil schools in their neigh- 

 bourhood, many classes in which instruction of a very elementary 

 nature only had been given being at the same time closed." A 

 determination has been made of the average ages at which 

 students in the Department's science classes obtained surcisses 

 in the I-Jemeiilary am' .\dvanced .Stages, It was found thai the 

 average age in D.iy Schools for a student to obtain a firslchiss 

 elementary success was about 14, and for a .second-class 

 Advanced about 15J, while in the evening classes the ages were 

 respectively .ibout 18 and -21. In addition to statistics, anti 

 information as to science instruction and technical education, 

 the Report contains the reports of the work of the (Jeologlcal 

 Survey of the United Kingdom, and of the Committee on .Solilr 

 Physics.
