When did the word telepathic appear in Watership Down?

In "Watership Down" by Richard Adams, the Word "telepathic" appears in the context of describing the psychic connection between rabbits, particularly in relation to the character El-Ahrairah. The book explores themes of communication and understanding among the rabbits, enhancing their world. Although I can't provide the exact page or location where the term is used, it contributes to the fantastical elements of the story.
