Conference, copies of which have been sent by the Association 
to our President and one of our secretaries. In the course of the 
discussion, Professor H. H. Turner, of the University Observatory 
at Oxford, pointed out the great value of taking pairs of photo- 
graphs on the stereoscopic plan, as explained in his paper ‘‘ On 
a simple method of accurate Surveying with an Ordinary Camera ”’ 
(Monthly Notices, R. Astronomical Society, December, Igor, 
LXII., 126). It is probable that Mr. Harrison’s suggestions as 
to County Surveys will be brought forward for renewed discussion 
at the meeting of the British Association at Leicester in 1907.

SOUTH EASTERN UNION OF SCIENTIFIC SOCIETIES. 
CONGRESS AT EASTBOURNE. 
Report to the Council of the Hampstead Scientific Society of its 
Delegate at the Congress. 
I attended the Congress of the South Eastern Union of Scientific 
Societies held at Eastbourne last June, as delegate of our Society. 
There were present delegates from twenty-eight societies, and 
a number of valuable papers were read. Conspicuous among 
them was that of Mr. Jonathan Hutchinson on ‘“‘ The Educational 
Value of Museums.” This should be circulated widely and placed 
in the hands of every body of local government and every scientific 
society. 
I fear our Society does not realise the benefits which accrue 
to it through affiliation with the Union. There is a long list of 
names of expert referees in various branches, whose knowledge 
is at our service. Lecturers are willing to come to us, in many 
cases for expenses only. Lantern slides and lectures are to be 
had on payment of carriage. Our Society will benefit by its 
affiliation in exact proportion as it makes use of the Union. 
As it seems right for us to make some return, I propose to submit 
my name as a lecturer of the Union. 
__ The object of the Union is, of course, to bring workers in science 
into closer touch, and I have reason to believe that it would, in 
some future year, welcome an invitation to hold its Congress in 
our midst.
