Can you help Identify this Liturgical Object?

Dear readers,

Perhaps you can help identify an object that was found in strorage at the Episcopalian diocese of Oregon office.  A Episcopalian priest of the diocese has asked  my help, but I myself haven't a clue.

Notice that this glass dish has a cover with four holes in it.  I would have assumed a dish for chrism, but I don't understand the need for the holes.   Three photographs of the object follow:







Thanks for your help!
