Should I call this potential employer, and what should I say?

About 3 months ago I asked my attorney to let me know if she heard of any openings for a legal secretary. I feel I would really like to work in the legal field. Within two days she emailed me of just such a position. At this other firm the girl they have currently is a student and will be returning to school in August. So I called, and the head secretary asked me to bring my resume by. She seemed really happy to have it, and seemed happy that I was interested.

She said they would be interviewing in July, and made sure she had my number and email.

Well, it’s July 17th and I haven’t heard anything yet. Should I contact her, and what should I say?
