The Secretary called attention to a paper in the *' Proceedings of the 

 Literary and Philosophical Society of Manchester," recommending napthaline 

 as a support for soft tissues when cutting sections. Its melting point was low, 

 and it did not shrink in cooling ; but he thought its scent very disagreeable. 



Mr. T. W. Burr believed that when it was properly refined its scent was 

 much better, and it was something like camphor in appearance. 



The following gentlemen were balloted for, and duly elected members of the 

 Club:— Mr. Thomas J. Baker, M.R.C.S., Major Frank Bolton, Mr. Horace 

 Dashwood, Mr. John R. Davies, Mr. John M. Knight, and Mr. John R. 

 Williams. 



The Secretary read a paper by Mr. William Webb, in reply to the letter from 

 Dr. J. J. Woodward, on Nobert's Tests, which was read at the preceding meet- 

 ing of the Club. In this paper Mr. Webb adhered to his opinion as to the 

 character of the higher bands, and the absence of true lines upon them. With 

 regard to his expression *' aerial polarised black lines of light,'" he endeavoured 

 thereby to convey his belief that they were lines of light in air, not on the 

 glass, and produced by a complication of refracted rays, the first refraction 

 being in the body of the glass, and the other refractions being of the emergent 

 rays from the parallel surface, and the opposite and unequal surfaces of the 

 bevelled sides of the incisions. His former paper was directed to the impossi- 

 bility of ruling bands to the aoWoo ^^ ^^ inch, and he should be agreeably sur- 

 prised if Dr. Woodward succeeded in resolving them. One of the objects of hia 

 paper was to bring out a discussion on the subject.
