Hi, I have sent 2 emails asking for these 2 articles German, I checked and find that I note the same reference. Please see below the 2 correct references that a ENT doctor asked for: Laryngorhinootologie. 1996 Dec;75(12):783-92. <http://www.ncbi.nlm.nih.gov/pubmed/9081287> [The Eustachian tube and its role in the history of otology. Images from the history of otorhinolaryngology, presented by instruments from the collection of the Ingolstadt German History Museum]. [Article in German] <http://www.ncbi.nlm.nih.gov/pubmed?term=Feldmann%20H%5BAuthor%5D&cauthor=tr ue&cauthor_uid=9914797> Feldmann H. Laryngorhinootologie. 1996 May;75(5):311-8. <http://www.ncbi.nlm.nih.gov/pubmed/8672218> [History of the ear speculum. Images from the history of otorhinolaryngology, highlighted by instruments from the collection of the German Medical History Museum in Ingolstadt]. [Article in German] <http://www.ncbi.nlm.nih.gov/pubmed?term=Feldmann%20H%5BAuthor%5D&cauthor=tr ue&cauthor_uid=9914797> Feldmann H. Sorry for this mistake, it is in the same German journal. Regards.
