There's
Mack, R. ed. 1988 Dictionary for Veterinary Science and Biosciences.
German-English/ English-German, with Trilingual Appendix: Latin Terms.
Berlin and Hamburg: Paul Parey Scientific Publications.
There's also another similar dictionary, (also on open shelves at the
British Library Boston Spa) which is French/German/English, but I don't have its
full reference.
