Campbell, Ann Arbor, Mich.—Any one at all familar with re-search work can at once see that Mr. Nead has condensed into histables and curves the results of a carefully planned set of experimentswhich must have involved a great amount of work on his part. Hedeserves much credit for the way in which he has carried out these ex-periments, for it is to the results of such systematic experimentation thatwe must look for further knowledge of the underlying causes whichdetermine the physical properties of steel. It will probably be manyyears before we have sufficient knowledge of all the factors of the problemof the constitution of steel, but every set of carefully carried out experi-ments such as Mr. Nead has made adds something to our knowledge andbrings us a lit
