The FRANKLIN I[lgSTITUTE ~OUR~TAL for November, 1881, contmns a description of a belt dynanometer involving the apl}lieatien of a new principle. Two {'orms of the machine were described and illustrated and a thiM form briefly indicated.

This third form has been developed and a dynanometer has been donstructed for the use of the Franklin Institute, as represented in tile annexed print from a gelatine plate produced by the beautiful photographic process employed by Mr. F. Gutekunst of this city.

This machine consists of a double gallows frame constructed of wood, fi'amed together at the fi}ot and sustaining at the top a cross block, from which the scale beam is suspended. This beam (by Fairbanks & Co.)is of bright steel, capable of weighing 300 lbs. and graduated to 25 lbs. by pounds and tcnths, the pound marks being "95 inch apart.

When the indicator is employed, a spring balance is attached near to the extreme end of the beam so as to exhibit 25 lbs. by pounds and tenths.
