There was once (around 1850) a theory about how snails could communicate "wirelessly" through great distances, allowing free communications around the world. This theory's practical result is known as the Pasilalinic-sympathetic compass, vulgarly known as the Snail telegraph !!
Cf. http://en.wikipedia.org/wiki/Jules_A...nd_experiments
There is a book in english with a chapter about the snail telegraph : http://books.google.com/books?hl=fr&...#search_anchor
I also stumbled on a whole article about it : http://en.wikipedia.org/wiki/Pasilal...thetic_compass
If you can, read the french page about Jules Allix : http://fr.wikipedia.org/wiki/Jules_A...ons_et_projets
And this book (which you can read online, unlike the english one) describes these "escargots sympathiques" : http://books.google.fr/books?id=QLw0...ad=0#PPA242,M1
There is also an article reproducing Allix's praise about Benoît and Biat-Chrétien work on the "Boussole pasilalinique sympathique" : http://pareiasaure.ifrance.com/allix.html
And a satirical lithography from 1869, pasted below :
