Tonks:
It has been years since Snape was a teen and while the spells in the 
book are rather advanced for a student, Snape knows them by heart 
and they are rather elementary to him now.  It is an old book, and 
he has forgotten about it. Maybe he expected to resume the Potions 
Masters position next year, after all everyone knows that the DADA 
position is jinxed, so he left some of his old stuff in that 
classroom cupboard.  He never expected Slug to tell a student to 
look for and use a book there. Who in there right mind would loan a 
book to a student!!  Snape would never do that, and it would never 
occur to him that Slug would.  Snape thought it was safe and he half 
forgot about it too.  I would have kept it somewhere else, but I am 
the semental type. To Snape it is just an old book. I think that he 
just forgot that it was there.
