It would help to know the age of the child. However, a child that bites can be removed from school or child care as a medical danger (HIV, hepatitis B etc.). You take the child, facing you, and with stern eye-to-eye contact, you say "no biting"-hold the look, and give a time out each event. Age makes a big difference.
Discuss with your pediatrician the behavior for helpful suggestions.

I suppose that other child must be doing something to antagonize the biting child and the biting child doesn't know a better way of getting his/her point across.
1) Talk to the student and find out why the child keeps biting the other. If the other child is doing something. Have them both discuss together. With young children, as I assume both of these are, this won't do much, but it is showing them that they need to talk to each other about a situation.
2) Tell the biting child it is not okay to bite people and seeing as this is the fourth consecutive time, give a consequence. Time out usually works with younger kids, especially if they are alone and see everyone else playing together.
Also tell the other student to stop whatever they are doing to anger the other child if this particular child is doing something wrong. Whether it be a sharing issue or name calling. If it keeps happening they need a consequence too.
You may also need to keep these two children seperated from each other for a day or two until they can get along.
3) Make sure to teach the children some nice ways to deal with problems that don't involve biting. The one child may have bitten the other simply because he/she didn't know another way to get his/her point across.
