Looking back into book...

I printed my book and then when looking back into it I spotted a few mistakes, one was that some of the explanations of images were in the wrong font, they were times instead of baskerville.
Also some of the spacing was different throughout the book, I wanted to keep the spacing between the type at 100 and some of the spacings were 150!

This is quite minor and some people will not notice it but it has annoyed me as I really notice it now. Seeing as they are only minor mistakes I am not going to worry about changing them if I do not have time but all mistakes have been adjusted through out the book if i was to print it again.
