LIVERPOOL ASSOCIATED SOIREE.—On Wednesday, Dec. 2oth, 
the learned and Scientific Societies of Liverpool held their Annual 
Soiree at St. George’s Hall, at which, amongst various other lec- 
tures and papers upon scientific subjects read on the occasion, was 
an interesting lecture upon ‘The Transformation of Insects,” as 
exemplified in the silk worm, the gnat, and the locust, by Dr. 
Hicks, which was illustrated by drawings shewn by the lime 
light, and another by Professor H. N. Moseley, on “ Life in the 
Surface Waters of the Ocean.” The objects exhibited ranged 
over a large and extended field of science and art. The ex- 
hibition of Microscopic objects by the members of the Micros- 
copical Society of Liverpool and the Chester Society of Natural 
Science were of the usual satisfactory character: Mr. T. S.-Shep- 
heard, of Chester, exhibited the rare rotifer Fedalion mira, and 
amongst the miscellaneous objects might be found a selection of 
botanical slides, by Mr. C. Vance Smith, illustrating the works of 
Sach and Thomé, and a series of original drawings from the micro- 
scope, by Mr. Rochfort Connor, illustrative of the adulteration of 
tobacco, snuff, beer, pepper, tea, coffee, and other excisable com- 
modities, which had been kindly lent by Dr. J. Bell, of the Inland 
Revenue Laboratory, and which drawings, we were informed, are 
the standards of reference at Somerset House. 
The Soiree was attended with its usual success, and we think 
that the example of an “ Associated Soiree” of Scientific Societies 
might be successfully and very advantageously followed by other 
large cities and towns.
