THE Committee regret that it proved impossible for them to complete 
their report, recommending a series of screw threads, in time for the 
present meeting of the Association. They therefore content themselves. 
with asking to be reappointed, in the hope that a little additional time 
will enable them to finish their work. 
Report of the ‘ Local Scientific Societies’ Committee, consisting of 
Mr. Francis Gatton (Chairman), the Rev. Dr. Crosskny, Mr. 
C. E. De Rancz, Mr. H. G. Forpuam (Secretary), Mr. Joun 
Hopkinson, Mr. R. Mutpora, Mr. A. Ramsay, Professor Sorias, 
Mr. G. J. Symons, and Mr. W. Whitaker, appointed by the 
Council in compliance with the following resolution referred to 
the Council by the General Committee : 
That the Council be empowered to appoint a Committee, as recom- 
mended in their Report adopted by the General Committee on August 23, 
in order to draw wp suggestions upon methods of more systematic observa- 
tion and plans of operation for Local Societies, together with a more 
uniform mode of publication of the results of their work. It is recom- 
mended that this Committee should draw up a list of Local Societies 
which publish their proceedings. 
Tse Committee have communicated with all the societies known to 
them which aeppar to fall under the designation of ‘Local Scientific 
Societies which publish their proceedings,’ giving to this definition a 
somewhat liberal interpretation, and they submit a tabular list of these 
societies with notes of their publications and other particulars. They 
are about 170 in number, and seem, from their rules and publications, 
to be centres whence local scientific information may conveniently be 
obtained. 
The Local Societies differ widely in character. Those which are 
established in large towns, and are not particularly well situated for 
carrying on systematic local investigations, are often of high scientific 
rank, and their affairs are administered in a business-like manner by a 
recular staff. On the other hand, there are numerous smaller societies.
