SOCIAL MEETING. 



HE thirty-third winter session of the Club was inaugu- 

 rated in a successful manner by a conversazione on 

 Thursday evening, 14 November, in the Exhibition 

 Hall, when over 600 members and friends attended. Some 

 graceful plants decorated the upper end of the hall adjoining 

 the well-stocked conservatory, whilst the side hall was utilized 

 for lantern displays. These annual social evenings of the Club 

 have long been well known for their enjoyable way of exhibiting 

 the work done during the year, and also because they give a 

 wider opportunity to the less scientific members and visitors to 

 learn a little practical science in an unusually acceptable way. 

 On this occasion the presence of some of the leading scientists 

 from Dublin and the fact that microscopy in all its branches

 at the hall at seven o'clock a refreshing cup of tea and its 

 accompaniments were provided by the lady members, which 

 lasted until eight, when the tables were cleared, and their space 

 soon occupied with different exhibits. The business of the 

 evening began by the President (F. W. Lockwood, C.E.)

 those who had come from Dublin to assist their friends and 

 co-workers in Belfast. This over,
