Simple cysts.—Some writers mention these as occur-ring in the heart. They are, however, extremely rare, andtheir exact pathological significance has still to be worked Ogle met with a blood cyst in the pericardium which hethinks was due to the rupture of one of the branches of the Parasites.—A Treatise on the Entozoa of Man and Animals, by Dr SpencerCobbold, p.

I met with in ^^ post-mortem theatre of the EdinburghRoyal Infirmary during the past session (the specimen oc-curred in a case of Dr WylHes, with whose permission it isrepresented here) a cyst the size of a small orange, con-taining partly fluid and partly clotted blood, is situated inthe anterior wall of the left auricle, between the auricleand the posterior surface of the base of the aorta. The aorticorifice was extremely stenosed, the two cusps (there were onlytwo cusps) being converted into thick, dense, calcareousmasses; there had apparently been old ulceration at the baseof the cusps, and between them a depression, which passedbackwards in the direction of the cyst, existed, and se
