112 PROCEEDINGS OF THE SOCIETY. 



in insects, and suggested that they would form a highly interesting 

 subject for the further examination of microscopists, the more par- 

 ticularly as Professor Graber stated that for want of time he had been 

 unable to complete the observations that required to be made in 

 order to establish their exact character. The organs described were 

 drawn on the black-board by Mr. Stewart (see p. 45, and Plate IV. 

 Figs. 1, 1 a, 1 b, 2, and 2 o). 



Dr. Matthews inquired if the hairs were supposed to perform the 

 function of otoliths. 



Mr. Stewart regarded the mode of nerve-termination of these 

 organs as presenting the closest resemblance to that of the human 

 auditory apparatus. He thought there seemed in all cases a special 

 provision to prevent the otolith from touching the hairs. If they 

 examined it in the bony fish they would find that there was an otolith 

 convex on the side facing the brain, and this would come in contact 

 with the hairs, but for the fact that they also constantly found deep 

 grooves, which seemed as if they were to ensure that the otolith 

 should be in as close a connection as possible without resting upon them. 



The Chairman proposed a vote of thanks to Mr. Crisp for his very 

 interesting description of the important observations referred to, and 

 to the authors of the other papers which had been read that evening, 

 which was carried unanimously. 



The List of Fellows nominated for election as members of the 

 Coimcil at the ensuing annual meeting, was read in accordance with 

 the 44th bye-law. 



The following objects were exhibited : — 



Mr. Ingpen : — (1) An old camera lucida, of the form designed by 

 Amici, in which the image of the object is twice reflected, first by an 

 opaque, and then by the first surface of a transparent mirror; the 

 method being identical with that of Dr. Hofman described at the last 

 meeting. (2) Also another, by Amici, in which the image of the 

 object was reversed by a right-angled prism. 



Dr. Matthews: — Specimens exhibiting parasitism of a coral on a 

 sponge. 



Mr. F. H. Ward : — Sections of mistletoe from an apple-tree — 

 double stained. 



Mr. Crisp : — (1) The Sorby miniature micro-spectroscope (see 

 J). 81). (2) Kecklinghausen and Meyer's pathological micro-photo- 

 graphs. (3) Specimens of microscopic printing issued by the 

 Security Printing Company. (4) Muhr's " Wall Charts " of the 

 anatomy of the head of insects. 



Mr. Heneage Gibbes was elected a Fellow of the Society, and 

 five gentlemen were proposed for election at the next meeting.
