recenlty got given this book ,-
Vivisection or Science - by Pietro Croce,
bought from [link= http://www.animalaidshop.org.uk/books.htm ]Animal Aid[/link] and although only on page 25 have found it to be a fantastic informative book.
Written by a once vivsector , he reports on why it is so pointless and gives examples of how people in the late 1800s also voiced their opposition to animal experiments with regards to that it just does not work.

A great book worth reading

I was also given Vivisection Unveiled by Tony Page, again available from [link= http://www.animalaidshop.org.uk/books.htm ]Animal Aid
[/link]I have yet to read it all but have looked through it and cant wait to get started on it either.

Both books look also at the different results that come from same animals but different genders/sexes and also the different results from when experiments on animals are performed at night and in day aswell and the very different results recieved by these situations.
