the museum-can't find the skeleton's arm

Hi, I am stuck on the museum scene (I believe it is the louvre day 5). I got the skeleton's legs, torso, skull, and left arm attached but now I can't find the right arm anywhere! Can anyone tell me where it is located? I would really appreciate it!

anitahill,
I think there's one hidden in the wing in the upper right hand corner, and one in the glass table, lower mid-left.
