Presfernal Calcißcatio7i.—\Jnäernesiih the sternum and sympa-thetically affecting this bone in part, a peculiar calcification processoccurs in fattened cattle and sheep. This deserves to be mentionedon account of its scientific interest and the possibility of its beingmistaken for tuberculosis. In the animals in question one observes, Fig. Presternal , seetion of ihe sternum; 5. normal sternal päd; c, lime deposits. in the päd formed of elastic and fat tissue, tumors with a roughenedsurface and hard consistency, frequently of the size of a hazel nutor that of the fist. After making a cross-section of the sternumwith a saw, it is apparent that the tumors consist of a strong con-nective tissue framework, in the cavities of which a pure whitegypsum-like mass is deposited. This mass consists of carbonateand Phosphate of lime. The periphery of the tumors is delimitedby strongly-developed conuective tissue. In some cases, but notregularly, the tumor penetrates into the sternum in consequence ofa proliferation of the part of the sternum which is directly in con-tact with the tumor. 8KELETAL MUSCCLATÜRE 355 No parasitic cause Las been discovered for the above describeddepositiou of lime underneatli the sternum.
