Now that our Bengal is well, she is chasing our new kitten

Any ideas for a solution to this problem?:

We have three cats: Merlin ( Male flame-point Himi), Guinevere (female Bengal), and Tama-Chan (female kitten). The Bengal is being very aggressive towards the female kitten. She chases her, swats at her, and tries to trap her. Merlin, is being an absolute angel to the new kitten. He licks her, plays with her, lets her eat his food, drink his water, steal his bed.

We have had the kitten for about three weeks now. Any ideas?
