is a small boss covered with minute hairs, without ring bases/ 

 and bluntened, probably open ; they have internal ring (not 

 spiral) structure similar to an artery. The examination of the 

 mandibles of a gadfly, Tabanus bovinus, will show the most 

 wonderful saw in the world, having 10,000 to 16,000 teeth per 

 inch on one edge, while the other is the keenest blade in exist- 

 ence. After describing the sting of a hornet, Vespa crabro, 

 he draws attention to the pygidium of a flea. If the right- and 

 left-hand edges are examined, a Eustachian tube will be seen. 

 The apparatus corresponds to the drum of an ear, and must 

 have an air-passage to equalise the pressure on either side. At 

 the base of the haltere in a blowfly a similar tube is easily seen. 



At the 509th Ordinary Meeting of the Club, held on June 22nd,

 event, but they had since thought it necessary to abandon the 

 idea, as it was felt that any kind of rejoicing would be out of 

 harmony with the prevailing feeling at the present time, and 

 he thought they would all be agreed that the most dignified 

 thing they could do under the circumstances was to defer that 

 celebration. He wished also in the first place to say that the 

 Hon. Editor had inserted in the last number of the Journal a 

 very interesting account of the early history of the Club, which 

 would no doubt be read with great pleasure by the members. 

 Another point was that they had the pleasure of seeing that 

 evening present at their meeting three of the original members 

 of the Club Mr. R. T. Lewis, who had acted as their Honorary
