course of his description Prof. Marsh remarks that, 

 from the relatively large size of the humerus, the horned 

 Dinosaurs were evidently quadrupedal ; and since the 

 presence of a postacetabular process to the pubis is 

 evidently (as exemplified in birds and Iguanodon) in 

 some way connected with the bipedal progression, it 

 may be a fair inference that, owing to the resumption 



of a quadrupedal progression in the forms under con- 

 sideration, this process has been lost. We may note 

 that the pubis of Triceratops seems undoubtedly 

 to correspond with the pre-acetabular portion of the 

 pubis of Stegosaurus, and not with the pubis of Megalo- 

 saunis, which represents the postacetabular portion of the 

 latter.

The nature of the dentition clearly shows that the 

 loomed Dinosaurs of the Laramie were of herbivorous 

 liabits, and as it seems impossible that any carnivorous 

 Dinosaurs could have successfully waged war against such 

 giants, we may fairly regard them as the lords of the 

 plain in the distant Cretaceous epoch. 



In conclusion we may venture to express the hope that 

 future "finds" will enable the palaeontologists of the 

 United States to give us ere long a complete restoration 

 of the skeleton of these mighty denizens of a long-past 

 epoch.

THE MEETING OF THE BRITISH ASSOCIA- 

 TION AT LEEDS. 



C\^ September 3 the sixtieth meeting of the British 

 ^-^ Asso ciation will be opened at Leeds by the President- 

 elect, Sir F. A. Abel, F.RS. The address, the lectures to 

 the Association, and that to the operative classes will be 

 delivered in the Coliseum, in which upwards of 3400 

 persons can be well and easily accommodated. By the 

 courtesy of the Mayor and Corporation, the Victoria Hall 

 will be used as the reception-room, and other rooms in 

 the Town Hall will be provided for the various offices. 

 Excellent Section rooms within short distances of the 

 Town Hall have been secured by the kindness of various 

 public and private bodies. 



A guide-book, giving an account of the geology, history, 

 places of interest, and manufactures of Leeds and the 

 district, has been prepared, and a list of lodgings and hotel- 

 accommodation has been drawn up. Various facilities 

 are offered by the railway companies. 



His Worship the Mayor of Leeds proposes to invite 

 the members and associates to a reception and conver- 

 sazione in the Municipal Art Gallery ; a soiree will be 

 given by the Executive Committee ; and an afternoon 

 reception at the Yorkshire College. 



From the facility of access due to its central position 

 in the railway system, from the number ^nd variety of its 

 industries, and from the beauty and interest of the country 

 by which it is surrounded, Leeds offers exceptional advan- 

 tages to visitors, of which many eminent members and 

 foreign men of science have already expressed their 

 intention of availing themselves. 



Members interested in applied science and manu- 

 factures will be able by the courtesy of employers of

labour to acquaint themselves with most of the modern 

 processes by which the wealth of England is being 

 augmented. They will be able to follow the smelting 

 and working of iron until it is converted from clay-iron- 

 stone and hematite into tools, engines, pumps, textile 

 machinery, and, in short, into everything which can be 

 made of iron or mild steel. They can inspect the 

 modern improvements in the old industry of Leeds by 

 which wool, shoddy, and mungo are converted or recon- 

 verted into woollens or worsteds, and subsequently into 

 clothes. Tanning, boot and shoe making, brewing, and 

 the manufacture of sanitary, fire-resisting, and artistic 

 earthenware employ a large number of hands ; while 

 among minor industries may be noted the manufacture of 

 sulphuric acid and other chemicals, of bottles, of paper, 

 of soap, of matches, and of soda-water. 



Those interested in geology or scenery will find on the 

 coast and in the diversified strata exposed, much that will 

 instruct and interest them ; while, to the historian, the 

 architect, and the archaeologist, the minsters, the cathe- 

 drals, the abbeys, the churches, the castles, the Roman 

 remains, and the historic houses will furnish many objects 

 worthy of attention. 



Excursions may be taken or will be organized, in many 

 cases by invitation, to most of the following places : — 

 Add Church, Kirkstall Abbey, Temple Newsam, Farn- 

 ley Hall, Harewood House, Boston Spa, Low Moor 

 Iron-works, Pontefract Castle, the Ruskin Museum, 

 Walton Hall and Wakefield, Aldborough, Beverley 

 Minster, Bolton Abbey and Skipton, Castle Howard, 

 Ingleborough, Harrogate, Hemsley and Rivaulx Abbey, 

 Malham Tarn and Gordale Scar, Richmond, Ripon 

 Cathedral and Fountains Abbey, Settle and the Victoria 

 Cave, Scarborough and the coast, Wensleydale, and York.
