A springer spaniel!
The cross section of arch rib except the part closed to the arch springer is new dumbbell-shaped section which is different from the traditional one.
My surprise and perplexity were great to discover, by touch more than vision, Miss Isabella's springer, Fanny, suspended by a handkerchief, and nearly at its last gasp.
Perhaps a better role model for bo was Millie the springer spaniel, who not only "dictated" a book to her owner, Barbara Bush, but also gave birth to a camera-ready litter of puppies.
