529791_0001This manual on the spectroscope is part of Macmillan’s Nature Series and is bound in publisher’s brick red cloth with gilt and black stamped front cover. Pasted onto the title page is a colorful watercolor spectrum with the initials “J.B.L.” next to it. The frontispiece is a tri-fold colored plate of spectra and there are sixty figures in the text, many illustrating types of spectroscopes. The front pastedown endpaper has the signature of previous owner David Peck Todd (1855 – 1939). An American astronomer and director of the observatory at Amherst College, Todd was chief astronomer at the Lick Observatory during the transit of Venus in 1882 and created the first known photographs of the transit. Spectroscopic measurements helped confirm the theory of the existence of an atmosphere on Venus, which appeared as though surrounded by a halo of light.
