We are interested in using a fusion process to complete information prior to the reasoning process about scientific discoveries. In particular, using fusion to complete the set of experiments used as the source of information of the process that led Claude Bernard to his discovery about the effects of curare. Our reconstruction of the discovery process is based on his experiments as they are illustrated in his notebooks. Our main problem is the lack of some important information in his notebooks containing descriptions of his set of experiments. In order to fill in the gaps in his set of experiments, we propose to use fusion between experiments. Prior to fusion, we must ensure that the experiments are compatible according to some similarity measures and depending on the objectives of the fusion. The paper presents our domain-independent approach for similarity checking and fusion, including similarity and fusion strategies.
