quick eye caught the arraugement in Mr. M.'s specimen, compared 

 not inaptly to those ornamental curves, a feat of the turning-lathe, 

 which one sees roughening the backs of ladies' watches. Mr. Miller's 

 specimen exhibited, as it lay in the rock, what, so far as he knew, no 

 other specimen of Ulodendron had yet shown, a true branch shooting 

 out at an acute angle from the stem, and fretted with scales of a pecu- 

 liar form, verging from irregularly rhomboidal to irregulai'ly polygonal. 

 It has been shown by Messrs. Lindley and Hutton, on the evidence 

 of one of their specimens, figured in the ' Fossil Flora,' that the line 

 of circular or oval scars, so remarkable in this genus, and which are 

 held to be the impressions made by a rectilinear range of cones, an 

 almost sessile row existed in duplicate, occurring on two of the sides 

 of the plant directly opposite. Its cones were thus ranged all in one 

 plane. The branch struck off from one of the intermedial sides, at 

 what in the transverse section would be at right angles with the 

 cones ; and though little can be founded on a single specimen, such, 

 certainly, is the disposition of branch that seems best to consort with 

 such a disposition of cone. It may be added, said Mr. M., that if all 

 the branches were also ranged in one plane like the cones, such a 

 disposition would not be quite without example in the vegetable king- 

 dom, even as it now exists. " Our host," says the late Captain Basil 

 Hall, in his brief description of the Island of Java, " carried us to see 

 a singular tree, called familiarly the ' traveller's friend,' — Urania being, 

 I believe, its botanic name. We found it to differ from most other 

 trees, in having all its branches in one plane, like the sticks of a fan 

 or the feathers of a peacock's tail." Influenced, perhaps, by Captain 

 Hall's description, and the figure of Urania given in his work, Mr. M. 

 had been accustomed, he said, to think of Ulodendron, though his 

 evidence on the subject was still far from ample, as a plant somewhat 

 resembling in its contour the old Jewish candlestick, as sculptured on 

 the arch of Titus. Mr. M. then went on to show that Ulodendron was 

 not, as surmised by the authors of the ' Fossil F'lora,' a mere form of 

 Lepidodendron ; though not improbably another of their genera, 

 Bothrodendron, was a mere form of it. At least, Ulodendron, when 

 decorticated, exactly resembles the latter plant, being mottled over 

 with minute dottings quincuncially arranged, and presenting its recti- 

 linear line of oval scars devoid of the ordinary sculpturings. After 

 several remarks on Lepidostrobus variabilis, which, as shown by spe- 

 cimens on the table, could not be the cone of Ulodendron, as Messrs. 

 Lindley and Hutton had surmised, but was unequivocally, as had 

 been inferred by Adolphe Brongniart, that of Lepidodendron, Mr. M,
