When I attempt to evaluate the expresssion

	 Limit[ x - Log[1 + E^x],  x -> Infinity]

I simply get back the original expression.  It seems to me that this
should evaluate to zero.

For that matter, when I evaluate the expression

	Log[E^x]

I also get back the original expression, instead of x.

I would appreciate any thoughts concerning these results.

I am running Mathematica 3.0.1 under Windows 95.
