Narrative:

En route; at FL250 we received an EICAS message stating engine bleed 1 valve closed; about 25 seconds after we had a wing and stabilizer anti ice fail and then a warning EICAS message anti ice fail in icing conditions. I was the pilot not flying and; after consulting with the captain; I declared an emergency; stated the problem and asked for lower. The controller assigned us FL240 and then down to 16;000. As I retrieved my manual to troubleshoot the closed message; all of the messages went away. After discussing with the captain; we cancelled the emergency due to the fact everything was working correctly and we continued down to 10;000 where ground contact was made leading to an uneventful visual approach to runway 35. I reviewed my manual for all of the messages that were presented in the event they returned. All procedures were complied with and maintenance was contacted on arrival with a description of the event.
