〃In due course of time the entire of the remaining nebulous mass would become affected with rotation from the more rapidly moving centre； and would assume what appears to me to be their inherent normal condition； namely； spirality； as the prevailing character of their structure； and as that is actually the aspect which may be said to characterise the majority of those marvellous nebulae； as revealed to us by Lord Rosse's magnificent telescope； I am strongly impressed with the conviction that such reasons as I have assigned have been the cause of their spiral aspect and arrangement。
〃And by following up the same train of reasoning； it appears to me that we may catch a glimpse of the primeval cause of the rotation of every body throughout the regions of space； whether they be nebulae； stars； double stars； or planetary systems。
〃The primary cause of rotation which I have endeavoured to describe in the preceding remarks is essentially cosmical； and is the direct and immediate offspring of the action of gravitation on matter in a diffused； nebulous； and； as such； highly mobile condition。
〃It will be obvious that in the case of a nebulous mass； whose matter is unequally distributed； that in such a case several sub…centres of gravity would be elected； that is to say； each patch of nebulous matter would have its own centre of gravity； but these in their turn subordinate to that of the common centre of gravity of the whole system； about which all such outlaying parts would revolve。 Each of the portions above alluded to would either be attracted by the superior mass； and pass in towards it as a wisp of nebulous matter； or else establish perfect individual and distinct rotation within itself； and finally revolve about the great common centre of gravity of the whole。
〃Bearing this in mind； and referring to some of the figures of the marvellous spiral nebulae which Lord Rosse's telescope has revealed to us； I shall now bring these suggestions to a conclusion。 I have avoided expanding them to the extent I feel the subject to be worthy and capable of； but I trust such as I have offered will be sufficient to convey a pretty clear idea of my views on this sublime subject； which I trust may receive the careful consideration its nature entitles it to。 Let any one carefully reflect on the reason why water assumes a rotatory motion when a portion of it is permitted to escape from an aperture in the bottom of the circular vessel containing it； if they will do so in the right spirit； I am fain to think they will arrive at the same conclusion as the contemplation of this familiar phenomenon has brought me to。
〃 BRIDGEWATER FOUNDARY； June 7； 1855。〃
I was present at a meeting of the Geological Society at Manchester in 1853； in the discussions of which I took part。
I was much impressed by an address of the Rev。 Dr。 Vaughan （then Principal of the Independent College at Manchester）； which is as interesting now as it was then。 After referring to the influence which geological changes had produced upon the condition of nations； and the moral results which oceans； mountains； islands； and continents have had upon the social history of man； he went on to say： 〃Is not this island of ours indebted to these great causes？ Oh； that blessed geological accident that broke up a strait between Calais and Dover！ It looks but a little thing； it was a matter to take place； but how mighty the moral results upon the condition and history of this country； and； through this country's influence； upon humanity！ Bridge over the space between； and you have directly the huge continental barrack…yard system all over England。 And once get into the condition of a great continental military power； and you get the arbitrary power； you cramp down the people； and you unfit them from being what they ought to beFREE And all the good influences together at work in this country could not have secured us against this； but for that blessed separation between this Isle and the Continent。〃
In 1853 I was appointed a member of the Small Arms Committee for the purpose of re…modelling and； in fact； re…establishing the Small Arms Factory at Enfield。 The wonderful success of the needle gun in the war between Prussia and Denmark in 1848 occasioned some alarm amongst our military authorities as to the state of affairs at home。 The Duke of Wellington to the last proclaimed the sufficiency of 〃Brown Bess〃 as a weapon of offence and defence； but matters could no longer be deferred。 The United States Government； though possessing only a very small standing army； had established at Springfield a small arms factory； where； by the use of machine tools specially designed to execute with the most unerring precision all the details of muskets and rifles； they were enabled to dispense with mere manual dexterity； and to produce arms to any amount。 It was finally determined to improve the musketry and rifle systems of the English army。 The Government resolved to introduce the American system； by which Arms might be produced much more perfectly； and at a great diminution of cost。 It was under such circumstances that the Small Arms Committee was appointed。
Colonel Colt had brought to England some striking examples of the admirable machine tools used at Springfield； and he established a manufactory at Pimlico for the production of his well…known revolvers。 The committee resolved to make a personal visit to the United States Factory at Springfield。 My own business engagements at home prevented me accompanying the members who were selected； but as my friend John Anderson （now Sir John）； acted as their guide； the committee had in him a most able and effective helper。 He directed their attention to the most important and available details of that admirable establishment。 The United States Government acted most liberally in allowing the committee to obtain every information on the subject； and the heads of the various departments； who were intelligent and zealous； rendered them every attention and civility。
The members of the mission returned home enthusiastically delighted with the results of their inquiry。The committee immediately proceeded with the entire re…modelling of the Small Arms Factory at Enfield。 The workshops were equipped with a complete series of special machine tools； chiefly obtained from the Springfield factory。 The United States Government also permitted several of their best and workman and superintendents to take service under the English Government。 Such was the origin of the Enfield rifle。 The weapon came as near to absolute perfection as possible； It was perfect in action； durable and excellent in every respect even in it's conversion to the breechloader it is still one of the best weapons。 It is impossible to give too much praise to Sir John Anderson and Colonel Dixon for the untiring and intelligent zeal with which they carried out the plans； as well as for the numerous improvements which they introduced。 These have rendered the Enfield Small Arms Factory one of the most perfect and best regulated establishments in the kingdom。
CHAPTER 20。 Retirement from Business。
I had been for some time contemplating the possibility of retiring altogether from business。 I had got enough of the world's goods； and was willing to make way for younger men。 But I found it difficult to break loose from old associations。 Like the retired tallow…chandler； I might wish to go back 〃on melting days。〃 I had some correspondence with my old friend David Roberts； Royal Academician； on the subject。 He wrote to me on the 2d June 1853； and said：
〃I rejoice to learn； from the healthy tone that breathes throughout your epistle； that you are as happy as every one who knows you wishes you to be； and as prosperous as you deserve。 Knowing； also； as I do； your feeling for art and all that tends to raise and dignify man； I most sincerely congratulate you on the prospect of your being able to retire； in the full vigour of manhood； to follow out that sublime pursuit； in comparison with which the painter's art is but a faint glimmering。 'The Landscape of other worlds' you alone have sketched for us； and enlightened us on that with which the ancient world but gazed upon and worshipped in the symbol of Astarte； Isis； and Diana。 We are matter…of…fact now； and have outlived childhood。 What say you to a photograph of those wonderful drawings？ It may come to that。〃* ＇footnote。。。 It did indeed 〃come to that；〃 for I shortly after learned the art of photography； chiefly for this special purpose。 。。。＇
But I had something else yet to do in my special vocation。 In 1854 I took out a patent for puddling iron by means of steam。 Many of my readers may not know that cast…iron is converted into malleable iron by the process called puddling。 The iron； while in a molten state； is violently stirred and agitated by a stiff iron rod； having its end bent like a hoe or flattened hook； by which every portion of the molten metal is exposed to the oxygen of the air； and the supercharge of carbon which the cast iron contains is thus 〃burnt out。〃 When this is effectually done the iron becomes malleable and weldable。
This state of the iron is indicated by a general loss of fluidity； accompanied by a tenden
