Beatrix Potter 
The Tale of the Flopsy Bunnies [EPUB ebook] 

FOR ALL LITTLE FRIENDS OF MR. MCGREGOR & PETER & BENJAMIN

It is said that the effect of eating too much lettuce is ‘soporific.’
I have never felt sleepy after eating lettuces; but then I am not a rabbit.
They certainly had a very soporific effect upon the Flopsy Bunnies!
When Benjamin Bunny grew up, he married his Cousin Flopsy. They had a large family, and they were very improv-ident and cheerful.
I do not remember the separate names of their children; they were generally called the ‘Flopsy Bunnies.’
