THE MECHANICSVMAGAZINE. LONDON, FRIDAY, JANUARY 18, 1861. THE INSTITUTION OF NAVAL ARCHITECTS. This Institution, -winch a score of eminent shipbuilders met to organise in London exactly a year ago*, is this week sending forth to the world, as its first-fruit, a splendid quarto volume of Transactions—the first, we hope, of many. The distribution of several hundreds of large volumes like this will necessarily occupy some days ; but many scores of them are already in the hands of the Members and Associates of the Institution, and, so far as we have yet learnt, have been received with even more than satisfaction. The contents of the volume are full of inte rest and value, comprising as they do a great variety of papers, both theoretical and practical, by some of the foremost authorities of the day. After the lists of Officers, Members, and Asso ciates, the Rules and Regulations, &c., and an account of the origin of the Institution in the form of an introduction by the Secretary, the volume proceeds with the addresses, papers, and discussions of the inaugural meetings in March last. The inaugural address of Sir John Pakington is a model of good sense, and proves that the officers of the Insti tution have acted wisely in electing him as their President. The Earl of Hardwicke’s address, although less free from the colour of political feeling, is a very cordial manifestation of sym pathy with the objects of the Institution. These addresses are followed by the first paper read—that on “ The Present State of the Mathe- “ matical Theory of Naval Architecture,” by the Rev. Dr. Woolley. This paper is in every re spect worthy of its prominent position, being a masterly review of its subject, and one which displays an independence of thought and a freedom of inquiry which are somewhat novel in connection with the science of naval archi tecture, and which promise much for its pro gress under the auspices of the Institution. Mr. Barnes’ account of “ Some Experiments for “ Finding the Heights of the Centres of Gravity “ of Her Majesty’s Ships ” follows Dr. Woolley’s exposition ; of this paper Mr. Scott Russell said,—“ This is one of the most valuable papers “ we naval architects have had submitted to us “ for many years.” Mr. Maudslay’s paper “ On a Proposed Form of Ship, with a Diagonal “ Midship Section ” succeeds, and is followed by an interesting discussion. Then come the papers “ On the Strength of Iron Ships,” by Mr. Grantham and Mr. W. Fairbairn, and a discussion upon them of a most serious and weighty character. In this discussion, Messrs. Martin and Ritchie, the two princi pal Surveyors of Lloyd’s, bore important parts, while Mr. Scott Russell undertook the task of criticising Mr. Fairbairn’s views, and showing that his suggestions, where they were practicable, had been anticipated by some shipbuilders. This discussion, dealing as it does from first to last with considerations that are vital to the shipbuilding profession, will doubtless be read with great interest. It is followed by Lloyd’s Table of Dimensions, and by a full report of Lloyd’s experiments upon iron plates and modes of riveting applicable to the construction of iron ships. Professor Airy’s paper on the “ Connection between the “ Mode of Building Iron Ships and the Ultimate “ Correction of their Compasses” succeeds these, and is itself succeeded by a discussion of the topic, in which Mr. Archibald Smith and other gentlemen shared. Mr. White’s account of his mode of building diagonal ships follows, and, after a discussion upon this, we meet with a paper on “ Tonnage Measurement,” by Mr. Samuel Read, late Master Shipwright of Sheer ness Dockyard, and with another on the “ New “ Tonnage Law of 1854,” by Mr. Moorsom, Sur veyor-General for Tonnage. In the latter paper are urged those changes which have been car ried out by the Board of Customs, with the sanction of the Board of Trade, since the paper was read. We next have Mr. Barnaby’s essay on “ Inventions for the Improvement of Naval “ Architecture,” to which we last week referred at some length, and which, in addition to the portions which we then more particularly noticed, contains a very able sketch of the pro gress of naval construction at successive periods of 100 years, from a time just anterior to the introduction of gunpowder up to the present moment. From this paper we also gather a fact which is well worth recording here, viz., that the University of Cambridge has had the distinguished honour of contributing to the science of naval architecture no less than five of its ablest writers, viz., the celebrated Phi- neas Pett, the equally celebrated Attwood, Professor Inman, Canon Moseley, and Dr. Woolley, the latter two of whom are living authors. Mr. Barnaby’s essay is followed by a paper on “ Chain Cables,” contributed by Mr. Lenox, the first chain cable manufacturer in the kingdom. Mr. Robert Murray’s paper on “ Means and Appliances for ^Economising Fuel “ iu Steamships ” comes next, and then Mr. Scott Russell’s two lectures on the “Wave-line Priu- “ciple of Construction,” with the second of which the March meetings concluded. The The publication of these lectures in the present volume affords the first convenient opportunity of studying, this remarkable theory that ship builders and other men of science have had presented to them. Previously, a knowledge of the wave-line principle could only be ob tained from scattered publications. The author promises, we are happy to observe, a further paper in which he will investigate the practical changes which are involved in the application of the wave-line principle to ships. The volume concludes with a table of dimensions of fifty steamers, prepared by Mr. Robert Murray. If the Council of the Institution would con sent to sell this volume to the public, they would doubtless soon dispose of the edition. But this they refuse to do. Its circulation will be strictly limited to the Members and Asso ciates of the Institution, to all of whom it is sent by the Secretary. Those of our readers who want the book must, therefore, make application for entrance to the Institution. For their encouragement we extract from the laws the following clause :—“ The class of Associates “ shall consist of persons who are qualified, “ either by profession or occupation, or by “ scientific or other attainments, to discuss “ with naval architects the qualities of a ship, “ or the construction, manufacture, or arrange- “ ment of some part or parts of a ship or her “ equipment.” It will be seen from these words that the class of Associates embraces gentlemen of very varied professions. Wo are happy to observe that persons of very high position have hastened to become Associates of the Institution, for in the list of Associates we find such names as those of Captain A. B. Beecher, R.N., Captain Sir E. Belcher, R.N., G. Bentinck, Esq., M.P., Admiral W. Bowles, C.B., the Marquis of Breadalbane, the Duke of Buccleucli, Lord Colchester, Captain the Hon. J. Denman, R.N., Captain the Hon. J. R. Drummond, R.N., C.B., Rear-Admiral the Hon. A. Duncombe, the Earl of Dur ham, the Earl of Gifford, Captain G. Gold smith, R.N., Vice-Admiral Sir Thomas Her bert, K.C.B., Vice-Admiral W. J. Hope John stone, Rear-Admiral Sir T. Maitland, C.B., Vice-Admiral W. F. Martin, Captain Sir F. Leopold M’Clintock, R.N., Vice-Admiral H. Meynell, Rear-Admiral the Hon. F. T. Pelham, C.B., Rear-Admiral W. Ramsay, C.B., the Earl of Rosse, J. H. Smyth-Pigott, Esq., Viscount Somerton, C. R. M. Talbot, Esq., M.P., Viscount Templeton, G. Tomline, Esq., M.P., Lord Willoughby d’Eresby, and many other persons of like distinction. At the end of the first year of its existence we find no less than 320 names—many of them representing, as we have seen, some of the most influential classes in the kingdom—on the Institution’s lists. No surer guarantee of success than this could be desired. During the past year but one series of meet ings, extending over three days, was held by the Institution. During the present year the holding of two series of such meetings is con templated, we believe, by the Council. The first series will be held about the first week in March; the second about the beginning of July ; a volume containing the proceedings of all these meetings will be published at the end of the year, and will form the second annual volume of the Institution’s Transactions. At the meetings that are to be held in March the construction of iron-plated ships-of-war will be discussed by several shipbuilders, engineers, and naval officers of eminence ; and as Parlia ment will then have assembled, many of its Members will, in all probability, attend for the purpose of enlightening themselves on this grave and national question. DEEP-SEA SOUNDING MACHINES. What is a mechanical invention ? Where does it begin, and where end ? Is it an idea, or an apparatus ?—an abstraction, or something that may be seen and handled ? Is it single or complex ? Does it spring into existence com plete, or is it capable of growth ! Is it of ne cessity the offspring of one brain, or may many minds contribute to it ? All these questions, and some others, are suggested by the letter from the pen of Dr. Wallieh, on deep-sea sounding machines, which we publish on another page. At first sight it may appear that a sentence which occurred in our article of the 28th December has given rise to this, as well as a former communication from the same gentleman ; but, although this may be true in a certain sense, it must be evident to every careful reader of Dr. Wallich’s communi cations that differences of opinion and feeling, which were sure to find expression in some form or other, existed before any notice of the “Bulldog machine” was taken by us. Wo hope, however, that this is the last time wo shall have occasion to speak of them. The whole business is very simple, and con sistent with perfect good faith on the part of all concerned. A little excess of sensitiveness —a little haste in the use of words has caused it all. The matter presents itself to us as fol lows :—During the late expedition of the Bull dog, the officers of the ship, as was natural under such a commander as Sir Leopold M’Clintock, exerted themselves to forward the special objects of the voyage, and,, among other things, sought to improve upon the imper fect machines which had been furnished to them for bringing up bottom from great depths. In this work the commander was particularly aided by Dr. Wallieh, the naturalist of the We write on the 16th of January.
