44 PROCEEDINGS OF SOCIETIES. 



The Scientific Evening. 



The last Scientific Evening of the season was held, by the kind 

 permission of the authorities, in the great hall of King's College, 

 on the 14th May, when there was a large attendance of Fellows and 

 an excellent display of objects and apparatus. 



It is gratifying to find that the opportunities afibrded by these 

 " Scientific Evenings " for the careful examination of objects and 

 apparatus, and for friendly conversation thereupon, continue to be 

 highly aj)preciated. 



The subjoined list will show that various departments of micro- 

 scopical science received valuable illustration from the novelty, rarity, 

 or remarkable merit of the objects, or from new means for their 

 exhibition. 



The Society was indebted to Messrs. Home and Thornthwaite, 

 Baker, and How, for the loan of a large nimiber of excellent lamps of 

 the most approved patterns. 



The Society exhibited the following from the late Mr. Farrant's

After death the tumor, which occupied the greater part of the 

 abdomen, was found to be a multilocular cyst, and to contain a glairy 

 fluid.
