Mr. Fairbairn on High Pressure Steam. At the opening of the Liverpool School of Science Mr. Fairbairn said :—' As a laborer in the field of science more particularly practical science I am sure you will allow me to give you a few examples of the great advantages which the industrial arts receive from the exact sciences and particularly from those constructions which are of much greater advantage to the industry and property of the community. With regard to steam I am quite sure every person here present must be aware of the very great advantages of that source of power that immense power we

At the opening of the Liverpool School of Science Mr. Fairbairn said :—' As a laborer in the field of science more particularly practical science I am sure you will allow me to give you a few examples of the great advantages which the industrial arts receive from the exact sciences and particularly from those constructions which are of much greater advantage to the industry and property of the community. With regard to steam I am quite sure every person here present must be aware of the very great advantages of that source of power that immense power we gee daily before us ; and if we look back to the days since James Watt lived to the present time every body will be convinced of the great improvements that have taken place by the application of science to that particular element. I recollect well in the early part of my own history that the steam engine never Worked above 7 Is to 8 lbs upon the square inch ; It then reached 20 Ms then 60 lbs. But now if we look at the locomotive engine the pressure is upwards of 160 Is and even 200 lbs upon the square inch. This is a great advantage and if we may judge by the great improvements which are taking place with re gard to the steam engine the locomotive as well as the condensing engine I am inclined to think that we are not by any means arrived at the full economy of the production of steam in this country and all other countries. Instead of working at the rate of 200 Ms upon the square inch I think it is very likely that it will reach 600 lbs.' Mr. Fairbairn said he would next allude to the application of iron to all the purposes of the industrial arts. That application was he said by no means limited and it would con tinue to extend. He instanced the construction of the Conway and Britannia bridges in proof of the principle of construction by experimental research. He had every confidence that the institution which they had inaugurated would be highly productive and prove of bene
