Improved stethoscope designed by George P. Cammann of New York introduced in 1855 is very similar to this design. The large bell-shaped chest piece was often helf before the patient’s mouth while the chest was percussed, to amplify “cracked pot” sound. Smaller chest pieces were used for ordinary auscultation. George Tiemann was the first to manufacture to Cammann stethoscope. This example was probably produce c. 1860 or later: it features longer flexible tubes attached by gutta percha connectors to the binaural ear tubes. The two parts of the instrument could be detached for carrying: this example could not be detached at time of cataloguing.
