Dear Colleagues, We are working right now with some bone remains taken from a historical site in Old Havana, which was apparently at one time a slaughterhouse, and we are very interested in studying livestock bone measurements. Unfortunately, we do not have access to materials relevent to this topic. We would like to request your help in sending us some of the works on this subject. We are particulary interested in the work of A . von den Driesch: A guide to the measurement of animal bones from archaeological sities. Peabody Museum Bulletin 1. Cambridge , Mass., Harward University,1976. Any help you can give would be very much appreciated. Thanks, José M.
