osseous matter

It is just at the critical moment that my osseous matter invariably plays me a trick.

"There must be some osseous matter behind my dura mater!"

Hitherto I had been tearing at it madly and making it worse; now I had got the end of the skein—"osseous matter"—and would soon unravel it.

"Osseous matter, osseous matter," I murmured mechanically, and it sounded so like an echo of her words that I am sure she thought me going mad.

In the female this is less strong and thick, and contains less osseous matter than that of the male.
