SIR - I could not disagree more with Jo Tanner in her defence of vivisection.

Humane alternatives exist in the form of National Anti-vivisection Society and the Lord Dowding fund for Humane Research. They unfortunately do not receive any Government funding - but why would they? Because governments don't really want you to find out the despicable and barbaric ways in which animals are used and abused in laboratories. There's far too much profit in pharmaceutical companies - after all, that's all that matters, isn't it?

I appeal to anyone who has at any time owned and loved an animal to research the real truth about vivisection - but be prepared for other distress at what you will see - and go on, do something about it! Write to your MP and contact companies asking for their policies on animal testing.

Like the concentration camps, these animal torture centres must go.

MAL BROWN,

Great Witley.
