unit time per unit area at a %\\cn distance— just, for 

 example, as Newton's Second .Axiom defines two masses 

 to be " equal " when the same force produces the same 

 acceleration in both ; an equality which is real if the sub- 

 str.itum at the basis of all bodies is the same, but merely 

 con-'cntional if it is not. 



If the distance of a star is known, we can determine 

 its intrinsic enerjfy, i.e. the quantity of energy which it 

 radiates into all space per unit time. 



Thus, let 1 be tlie intrinsic energy of a star whose dis- 

 tance from the earth is K : let K be the electromotive 

 force of its light as measured by the cell ; let /, /•, €- be 

 the analogous quantities for a candle or any other chosen 

 source of light : and let .A and a be the areas of the 

 aperture of the telescope and the selenium surface in the 

 cell. Then we have

Let us take, for example, a result which I'rof. Hoys 

 recently told me that he had obtained. He found, in 

 conjunction with Mr. Watson, of South Kensington, that 

 if the light of a standard candle was observed across a 

 valley and almost in the line of sight of .-Xrcturus, the 

 light of the candle and that of the star seemed to be 

 equal when the candle was at a distance of five-eighths, or 

 •625. of a mile. 



Now, let .f be the distance at which the candle light 

 seems to be as bright as that of the star. Then

.And if I) and li are the diameters of the telescope 

 aperture and the circular layer of selenium in the cell, 

 we have from (3 



I'ut, now, r = 9 feet, <• = 10, E = 8-2, U = 24 x 25 

 millimetres, d = 2 m.m., as in our experiments, and we 

 find 



.V = 3 JOG feci, nt.nrly

This agrees remarkably well with the observation of

FiWERAL OI- PROFESSOR HUM.EV. 

 I .\ accordance uith his own wish, the late I'rof Huxley 

 ■* was buried at the Marylebone Cemeter)-, I'inchlcy, 

 last Thursday afternoon. The coffin came up from ICast- 

 bourne in the morning, and the numerous mourners 

 assembled at the cemeter>- to meet it. Wreaths from 

 members of the family, and from friends and fellow 

 workers of the great naturalist whose loss we mourn, 

 covered the coffin. The Kfiyal College of .Science, with 

 which Huxley was connected so many years, sent a large 

 wreath, and there were also wreaths from Lady Hooker, 

 Mrs. Tyndall, the members of the staff at the Koyal 

 < iardcns, Kcw, Mr. Herbert .Spenccr,Sir Henry Thompson, 

 Sir Henry Koscoc, Messrs. Macmillan, and the Kditor of 

 Naiikk, among others. 



The funeral service was performed by the Kev. J. 

 Llewelyn Davies, an old friend of I'rof Huxley's, now 

 rector of Kirby Lonsdale, but formerly vicar of .Maryle- 

 bone, where he was for a long time Huxley's neighbour. 



The family was represented by Mrs. Huxley, the two 

 sons, .Mr. Leonard Huxley and Mr. Henry lluxky, and 

 three daughters, the Hon. Mrs. Collier, Mrs. Waller, and 

 Mrs. Lckersley ithe remaining daughter, Mrs. Koller. is 

 in Switzerland with her husband, who is ilL, .Mrs. Heath 

 (a niccc), and two sonsin-lau, the Hon. John I Oilier 

 and .Mr. K. W. Waller.

No announcements of the funeral were sent out, and 

 the large number of distinguished men who attended, 

 and the various learned Societies that sent representatives, 

 did so on their own initiative. The Royal -Society wa> 

 officially represented by Lord Kelvin, Sir John Evans. 

 Prof. Michael Foster, and Sir J. Lister, many of the 

 Fellow s also being present. The C.cological Society wa> 

 represented by Dr. Henry Woodward, Dr. Blanford. 

 and Prof, lionney. Dr. Krankland, Mr. Crookcs, Dr. 

 Thorpe, and Dr. Gladstone «ere the representatives of 

 the Chemical Society. The mourners from the Royal 

 College of .Science included I'rof Riicker, Prof Norman 

 Lockyer, CIS., Prof Tilden, Prof judd, C.H., Prof. W. C. 

 Koberts-.-Vusten, C.15., Prof Howes, Prof Farmer, Dr.

 J. H. Teall, Mr. F. W. Rudkr, and Mr. E. T. Newton,

 the Royal Society not included in the above, there- 

 were present Prof E. Ray Lankestcr, Dr. Dallinger.

 Brunton, Dr. Sclater, Prof Carey Foster, Prof (i. 

 H. Darwin, Sir James Paget, Dr. Burney Yeo, I'rof.

 .Among the other mourners were .Mr. Walter Troughton, 

 representing Mr. Herbert .Spencer, who was prevented 

 bv illness from being present, Dr. T. K. Rose, .Mr. W. 

 Darwin, Mr. .A. H. Heath, Mr. S. Highley, Mr. W. S. 

 Stewart, Major-(;eneral .Sir Richard Pollock and Mr.

 Windsor, the Rev. 'l). 1). Jeremy. Dr. J. Malecki. Mr. 

 J. Spiller and Mr. and Mrs. Briton Riviere. 



The funeral was at first announced to take place at 3 

 o'clock, whereas the time fixed upon was 2'30. Owing to a 

 delay in the train, a number of workers in science, from 

 the .\lidlands and the .North of EnglantI, did not arrive 

 at the cemetery until the ccremonx was over, anil thus, to 

 their deep regret, they were deprived of the nielancholv 

 satisfaction of being present when the remains of an 

 esteemed master and frientl were laid to rest. 



The Miemory of Huxley will always be cherished among 

 men of science, and it is imperative that there should 

 be a permanent memorial of some kind to show the 

 world how great is their regard for him. The 

 memorial should be a truly national one, and not 

 limited to any p.irticular institution. We understand 

 that the Dean of Westminster is willing that a tablet 

 shall be erei ted in the Abbey if desired, and this is 

 one of the forms which the memorial might take. ,Sir 

 William Flower suggests another form, in a letter to 

 the 'I'iiius of .Monday. He writes : 



" In the great hall of our national Musemn of Natinal 

 History the noble statue of Darwin will h.ind down to 

 posterity the image of the man as he appe.ired lo all who 

 knew him in life. Near this will soon be pla( ed another 

 statue remarkable for the accuracy with which the 

 striking personality of Owen is represented, as all who 

 see it now at the Roval .Acidemv Exhibition can testifv.
