thicken, and come to the consistence of a stiff and glutinous gelly. These 

 vesiculae * were doubtless formed from the tenacity of the matter between the 

 membranes of the bladder, in its oblique passage through them ; for that being 

 so glutinous, it was here detained till its surface was condensed into a firm 

 coat, and so by the coming of more matter was forced into the cavity of the 

 bladder. This I suppose, from our finding two of these ova in a distinct sinus 

 from the rest, between the coats of the bladder, at the entrance of each 

 ureter. 



The liver we found very large and hard, of the colour and substance of a 

 boiled one. It adhered to the peritonaeum on the external part, and by its vast 

 size had so straitened the thorax, that there was very little room for the lungs. 

 The lungs were of a livid colour, adhering close to the pleura on the right side ; 

 upon incision, we found them wholly replete with a purulent matter, and a 

 stone of the size of a cherry-stone in one lobe. — Dividing the pericardium, we 

 found a fungous substance covering the heart all over ; and fibres from it, that 

 ran to the pericardium in a great number ; so that they were by these fibres 

 every where united. — The heart was very large ; the right auricle and ventri- 

 cle were one large undivided cavity, and therein a large polypus ; which ran up 

 the descending branch of the vena cava, to the very jugular ; another part was 

 distributed to the pulmonary artery. In the left ventricle was another polypus, 

 not so large as the former : it had two branches, one in the pulmonary vein ; 

 another in the arteria magna or aorta. One of the vesiculae being opened, had 

 a large cluster of small ova, as large as grapes, all replete with liquor. All the 

 rest contained nothing but serum. 



On an extraordinary Effect of the Power of Imagination. Communicated by 

 Mr. Edward Smith, Sec. to the Phil. Soc. at Dublin, as it was brought before 

 that Company. By Mr. St. George Ash, R. S. S. N° 188, p. 334. 



One Elizabeth Dooly, of the county of Kilkenny, aged 13 years, in January 

 last. Her mother, when with child of her, was frightened by a cow, as she 

 milked it ; thrown down, and struck on the temple, near the eye, by the cow's 

 teat. This child has exactly in that place a piece of flesh resembling a cow's 

 teat, about 3 inches and a half in length. It is very red ; and has a bone in the 

 midst about half its length. It is perforated, and she weeps through it. When 

 she laughs, it wrinkles up, and contracts to two thirds of its length ; and it 

 grows in proportion to the rest of her body. She is as sensible there as in any 

 other part. 



• It is probable that these vesiculae were hydatids.
