Was Lincoln’s coffin opened in February 1866 ?

[RJNorton]

I was curious about the sentence which reads, "The face was examined through the glass covering which underlies the outer strata of the case..."

What glass covering?

Also, I am curious as to why this might have happened in the first place. The article says the Missouri Democrat was the source and gives a February 10 date, so this allegedly happened fairly early in February. We know the remains were identified December 21, 1865. So why, less than two months later, would yet another "official identification" even be necessary? Was the December 21 opening not considered "official?"

I searched for other newspapers that carried this same article and found quite a few. For example The Launceston Examiner (Tasmania, Australia) carried the article on June 13, 1866, and gave its source as the March 13, 1866, London Evening Sun.
