A New Edition of the Work of the late Mr. TREDGOLD, edited-with further Experimental Researches on the Strength of Cast Iron and other Metals-by EATON HODGKINSON, F.R.S., now being much called for, and holding the highest reputation as a Standard Work of reference, for the use of the Scientific and Practical Builder, is now presented together as a fifth edition of Tredgold, and a second edition of Mr. Eaton Hodgkinson's "Experimental Researches."

It is intended by Mr. Hodgkinson to publish in a collected volume, all his valuable experiments scattered in the publications of several Scientific Works, viz.: "Transactions of the Royal Society of London," "The House of Commons' Report on Iron," and "The Memoirs of the Manchester Society."

The Second portion of this Work may be had separately for the convenience of those who desire to possess, alone, Mr. Hodgkinson's "Researches."

November, 1860.
