The disease is, for the most part long stationary, when, without any apparent cause, the action of the vessels acquire vigour, the pulsation becomes ‘ perceptible, and the tumour sensibly increases. The colour of the tumour is a blackish blue or purple, and on the most prominent part there is an excrescence like a mulberry, which bleeds profusely from time to Under this head I put such tumours as are of a fleshy rzon~ :istence, and not distinctly of glandular origin, but which spread equally around. culiar action. Fuse us HEMATODES of Mr. Hey. This disease may take its origin in muscle, cellular membrane, or even bone. Some times it begins as a distinct tumour; sometimes as a general enlargement of the part; as of the leg, thigh, or shoulder, generally it is not painful. It is irregularly soft, (of uneven density,) and to the feeling there is a sensation of extravasab ed fluid, yet not of a fluid in a distinct sac. There is no in regular hardness ; and no puckcring of the skin. If it be seated under the fascia the distension has a considerable elasticity. The veins on the surface are much enlarged.

It destroys the patient by hnemorrhagy. When dissected it is like a mass of placenta.

When its contents are examined after extirpation, there is a greasy, ash coloured substance in the midst of a vascular bed.

I have dissected a tumour oi" large size, which it was impossible to say resembled most the steatomatous tumour, or the vascular tumour described by Mr. John Bell, and in the substance of the tumour there were many cells full of liquid blood. These cells were not the irregular cavities of varicose vessels, but of a perfectly regular form, they had a smooth secreting surface. I would have called them hydatids but for their contents. The nature of the osrzo-srnnronmrous and osrro-ssaconames tumours is but little known; the first term implies "1a ' «mmw‘ mm mossy |
