If you look at it at 400% there are some oddities. It could be a relic of a bad copy, but some letters seem to be "enhanced". For example the small 'e' in the word intrepidity in the first line. Looks like upper part of the 'e' is more rounded, than the 'e' in the word 'while' three words later in the same line.
Further down, in the 18th line 'Upon sweeping', the two 'e's look strangely different.
Like I said, it could be a relic of the copier.
