ON STANDARDS FOR THE ANALYSIS OF IRON AND STEEL. 53 



because of the interest this firm has always shown in promoting the 

 cause of scientific metallurgy. 



Professor Langley further says: — 'lean make the fifth standard, the 

 0"08 carbon suggested by your Committee, only it will take probably 

 about two montlis. I will start upon it in a short time, as soon as I 

 can make the right kind of stock, which will have to be Bessemer, for I 

 can blow a heat as low as that without trouble.' 



Within the last few days a letter has been received from Professor 

 Langley as representing the University of Michigan, and from Mr. 

 William Metcalf, on behalf of the American Society of Civil Engineers, 

 stating that the samples have been despatched to each of the four 

 conntrios previously mentioned (Great Britain, France, Germany, and 

 Sweden). It is hoped that the analyses will be commenced almost im- 

 mediately, and that by the next meeting of the Association the work may 

 be in a forward condition. 



Third Report of the Committee, consisting of Professors Tilden 

 and Eamsat and Dr. Nicol (Secretary), appointed for the 

 purpose of investigating the Properties of Solutions. 



The Committee have to report that the work of investigating the solu- 

 bility of salts in the solutions of other salts has been continued during 

 the past year. Further experiments have also been made with the object 

 of determining the law governing the solubility of various salts in 

 alcohol and mixtures of alcohol and water of diti'erent strengths. In this 

 way a vast amount of additional data has been gathered together, but 

 the work of generalising from these has not progressed to the extent that 

 it was hoped last year, and the Committee must thei'efore ask for re- 

 appointment. 



Third Report of the Committee, consisting of Professors Tildex, 

 M'Leod, Pickering, Ramsay, and Young and Drs. A. E. Leeds 

 and Nicol (Secretary), appointed for the purpose of reporting 

 on the Bibliography of Solution. 



The Committee have to report that considerable advance has been made 

 in their work, with the following result : —
