On the Structure of a Lignite from the Old Red Sand- stone. Trans. Bot. Soc. Edin. vol. x. p. 312. The author proposes to name the wood which he describes PalceopUys MiUer'd. It was found by Hugh Miller at Cromarty. Von Mueller, F., and R. Brough Smyth. Observations on some Vegetable Fossils from Victoria. Geol. Mag. vol. vii. p. 390. The specimens were fruits from surface deposits, and were obtained from one of the deep leads at Haddon. One is a coniferous fruit allied to Solfnoslrobtis, of Bowerbank, to which the name of Spondi/Iostrobus Smylhii is given. Tlie others are not named, but suggestions are given as to their affinities, and these indicate, according to Von Midler, a flora analogous to that of the existing forest-belt of Eastern Australia.
