MESmith 1993 JOURNAL Bariloche, Prov. Rio Negro, Argentina Dec. 11 I attended the Argentine Mammal Society meetings in Bariloche Dec. 8-10. I presented a poster on abortion relationships, based on our paper in press in the Biol. J. Linn. Soc. I had a chance to talk with several Argentine mammalogists, which worked out well. On Dec. 11 I left Bariloche for the flight home. I poured off all the liquid nitrogen from the tank at the airport in Bariloche. When I reached San Francisco Gary met me and we went directly to Barker Hall to deal with the frozen tissues. They were still frozen solidly after 27 hours in transit.
