CORRESPONDING SOCIETIES. 59 
Society of Antiquaries, and it was hoped that this would become an 
_ annual gathering. They did not intend to compete with the Correspond- 
- ing Societies Meeting in this matter; they rather looked upon the 
_ Societies meeting here as representing the biological side of all the 
questions brought forward, whereas. the Society of Antiquaries repre- 
sented the purely archeological side. The survey of Kent had been pub- 
lished, others were in hand. The scale was only eight miles to the inch, 
but that scale would be found of sufficient size to note all the dis- 
coveries, and by means of the index he thought it would prove a most 
useful addition to the archeological publications of the country. 
: In conciuding the business of the first meeting the Chairman ex- 
pressed their indebtedness to Professor Meldola, who had acted as 
Secretary to the Corresponding Societies Committee throughout the 
year, and to Professor Lebour, who had consented to act as Secretary to 
the present Conference. 
At the second Conference the chair was taken by Mr. Wm. Topley, 
F.R.S., the Corresponding Societies Committee being also represented 
by Dr. Garson. The Secretary having read the minutes of the first Con- 
_ ference, the Chairman suggested that it would be convenient to follow 
the usual course, and before going to miscellaneous business to take up 
the suggestions and recommendations from the various Sections. 
Section A. 
Temperature Variation in Lakes, Rivers, and Hstuaries—Dr. Mill 
stated that the report of the Committee appointed last year had been 
adopted by Section A with a recommendation for its reappointment with 
a grant. The object of the Committee was to accumulate as great a number 
of data with regard to the temperature of the surface of lakes, rivers, and 
estuaries, and the sea near the shore, as could possibly be obtained, in 
order to discuss these in connection with the meteorology of the country. 
It was a problem of some difficulty, and the object sought to be obtained 
in bringing it before the Corresponding Societies was to spread the work 
over a very wide tract of country, so as to get such diverse conditions as 
it was impossible to obtain by a few isolated workers. As a result of the 
circulars sent to the Corresponding Societies last year, they had obtained 
twenty-four sets of observations on the rivers and some estuaries in Eng- 
land, twenty-one in Scotland, eleven in Ireland, and one in the Isle of 
Man. He did not think it necessary to read the names of the rivers, 
but he would merely say that he would be very pleased if the Delegates 
present, representing Societies which had not yet seen their way to take 
up this work, should, on their return, be able to find out some members 
able and willing to make these daily observations on exposed water in 
their own neighbourhood. He would be very pleased if they would 
communicate with him, or any other member of the Committee, and 
instructions would be immediately sent for setting the observations going. 
He had a report recently from the Manchester Geological Society 
showing the observations made there on the reservoirs of the Oldham 
- Waterworks—observations of great interest, and evidently, from the 
_ record published in the Transactions of the Manchester Geological Society, 
carried out with great detail and in a thoroughly satisfactory and trust- 
worthy manner. The success of the research depended entirely on the
