When I went to the bookstore during lunch today, the grammar book was still there, so I bought it for $25.00.
It's by Richard Green Parker A.M., 20th Edition, published 1855. Pretty good condition for a book over 150 years old.
All I have to say is....wow. Another book for my old book collection.
I came here tonight just to find out if you bought it. So glad you did! Sounds like an excellent find.
