In which we see monsters

Suppose, just for kicks, that you were an eighteenth century French veterinary student attending school outside of Paris. Naturally, you would be looking for fun, which would, naturally, lead you to want to go into Paris where there were interesting things happening. Equally naturally, the people running the vet school would want to keep you out of Paris, largely because of the interesting things that were happening there, and so they would attempt to provide you with entertainment options that kept you outside of Paris. And, naturally, the sorts of things that would keep you entertained would be things like this

and this

and this

and this.

All of which are housed in the Musée Fragonard at the École Nationale Veterinaire d'Alfort just outside of Paris. It is the oldest museum in the Paris region (housed in the second oldest veterinary school in the world), though it has only been open to the public for about 15 years. It is the ideal place to visit if you want to see the dried large intestine of a horse, or the bronchial tubes of a goat, or the uro-genital system of a bull.  It is also the ideal place to visit if you want to see human bodies that have been dried out and then painted so that their entire circulatory system is visible, and want to learn exactly how to go about creating such scientific models. 

And it is the place to go if you want to see monsters. Not, mind you, the Loch Ness Monster, or the Yeti, or the Kraken, but real monsters: calves with a single body and two heads, sheep with a single head but two complete bodies, calves with one head with two faces, lambs with a single body and head but eight legs and two separate spinal columns, a baby with legs fused together to make a tail, calves whose internal organs had not developed properly, and who as a result are hopelessly twisted, a pig with a single eye in the center of its bulging forehead, all preserved for the enjoyment and enlightenment of our veterinary student.
