osseous matter

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

"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.

"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.

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