The epithelial cells are not arranged on any definite plan, but are closely packed in irregularly shaped alveoli. If the alveoli are large and the intervening stroma is scanty and delicate, the tumour is soft and brain-like, and is described as a medullary or encephaloid cancer.
Such is the story, so far as Sutherland and Caithness are concerned, of Hakon's expedition as told in his Saga, which adds that after losing one ship in the Pentland Firth, while another was all but sunk in the Swelchie near Stroma, he sheltered for the night in the Sound north of Osmundwall, and finally landed again near Ragnvaldsvoe and went to Kirkwall.
We were making for South Ronaldsay, and had been beating about all night, making very little headway; and when the mist lifted before noon, it was discovered that we had been driven down by the current, and had come nigh to running into the black rocks of Stroma Island.
Peuch found that in one case the ovaries were of normal size three years after the establishment of the menopause. Kiwisch describes the structural change in this gland as consisting, on the one hand, of an increase of the connective-tissue stroma; and, on the other hand, the Graafian vesicles themselves undergo retrograde change.
But I heard an old woman crooning it to a child in a solitary cottage on the shore of Stroma, near the Swalchie whirlpool, and that was the tune she sang it to, if singing it could be called. 'I don't quite understand it, Mr. Ericson, said Mysie. 'What does it mean? 'There was once a beautiful woman lived there-away, began Ericson.
In the connective tissue stroma of the ovary between the follicles are scattered, or in some cases aggregated, epithelioid cells known as the interstitial cells, and it is stated that the cells of the theca interna are exactly similar to the interstitial cells.
If the cells undergo degeneration and absorption and the stroma contracts, the tumour becomes still harder, and tends to shrink and to draw in the surrounding parts, leading, in the breast, to retraction of the nipple and overlying skin, and in the stomach and colon to narrowing of the lumen.
This took place to the northwest of Stroma Island, and ever since the sea there has not rested, for as the water falls through the eye of the quern, it roars and rushes about, and the quern goes on grinding and grinding salt, and giving its saltness to the whole ocean.
