| Title | Paper, 'Note on the production of sounds by the air-bladder of certain siluroid fishes' by Thomas William Bridge and Alfred Cort Haddon |
| Date | 1894 |
| Description | The authors write: 'Dr. William Sörensen, of Copenhagen, has drawn our attention to the fact that, in our memoir on “The Air-bladder and Weberian Ossicles in the Siluroid Fishes,” published in the ‘Philosophical Transactions’ last year (vol. 184, pp. 65—333), we failed to do justice to the results of certain investigations which are embodied in his paper, entitled “Om Lydorganer hos Fiske: en physiologisk og comparativ-anatomisk Undersögelse,” and published at Copenhagen in 1884. In this paper Dr. Sörensen treats of the various methods of sound production in Fishes in general, and in the case of the Siluroid Fishes, describes the production of sounds by means of certain stridulating mechanisms (friction of the dorsal and pectoral spines), the “elastic spring” apparatus, and the paired extrinsic muscles of the air-bladder in the Pimelodinæ. We do not here wish to criticise his morphological conclusions, but to point out that, contrary to the assumption on pp. 270 and 301 of oar paper, Dr. Sörensen did make some experiments on living Fish.'
