The billing sheets for Probe Station #1 in lab 2261 have been lost. The first one disappeared on the 14th of the month, and the second one disappeared last evening. If someone accidentally took them out of the lab, could you return them to me tomorrow sometime. I am asking people to be honest and email me the number of times they used the system in October. This way we can bill for use of the system. Thank you, Dave Lubelski
