This is a 1929 film, so obviously the first one is done with special effects. It's extremely graphic nonetheless:
A woman's eye is slit open with a straight razor, causing liquid to ooze out. They actually used a cow carcass for the effect, so it is real to some degree.
A severed hand is shown, with bone protruding from wrist.
A man's hand has a hole in it, which ants crawl out from.
A woman is forcibly molested.
Two dead donkeys are seen, one is dripping blood from its nose, and has maggots crawling in the eye sockets.
A man is shot.
