Old Insulation

I have a 1948 Cape that has some old insualtion. The current insualtion in the attic is a brownish colored sawdust material encased in a black covering. What kind of insualtion did they use in homes built in the late 40's.

Thanks for the feedback. I'll do a little more research and see if I can narrow it down. Can I put new insulation over this or does the old need removed first?
