304 x 245 mm. 4to. Pages 27-42; 231-256. Tables, 4 plates (1 photographic); tables, 6 engraved plates. Dis-bound. Liveing and Dewar attempted to correlate line and band spectra with atomic and molecular states. They published seventy-eight papers between 1877 and 1904. Dewar and Liveing accurately determined the absorption spectra of many elements (especially metallic vapors) and compounds. They studied the general conditions affecting the excitation of spectra and, in particular, the ultraviolet emission spectra of many metals. George Downing Liveing became professor of chemistry at Cambridge in 1861; he was joined by Sir James Dewar in 1875 who became Jacksonian professor of experimental philosophy and directed the work of that chair to chemistry. "In 1878 they began a long series of spectroscopic investigations which continued till 1900. Their joint papers were republished as a single volume by the Cambridge University Press in 1915. This is the chief record of Liveing's scientific labours." DNB, 1922-1930, p. 511. Dewar: DNB, 1922-1930, pp. 255-257; DSB, IV, pp. 78-81. Liveing: DNB, 1922-1930, pp. 510-512.

Manuskript / Papierantiquität Signiert
All three items in good condition, with light signs of age, and minor traces of previous mounting. The two letters are both 2pp., 12mo, on bifoliums. ONE: Letter to Rücker of 12 May 1898. He explains that if he is 'not at the Society ready to give the Paper at 4.30' it is because he is 'engaged in getting new results [.] In any case I will appear if all goes well.' TWO: Letter to Lady Rücker of 30 May 1907. His wife has had an attack of bronchitis and 'is in the hands of Nurses and Doctor. In fact this place has almost become a permanent hospital for some years.' While he would be happy to join her party in 'happier circumstances', 'Under these circumstances it would be hopeless to make any future engagements.' THREE: Engraving of portrait of a middle-aged Dewar at his desk, pencil in hand, with papers and chemical instruments in front of him. Dimensions of print 8 x 11 cm; dimensions of paper 12 x 14.5 cm. In very good condition. Signed in pencil by Dewar in bottom right-hand corner of border: 'Very Sincerely | James Dewar'. No copy of this portrait in the National Portrait Gallery collection.
