MIDLAND UNION OF NATURAL HISTORY SOCIETIES. 
A meeting of the Committee of Management of the 
Midland Union was held on the 17tli of April, at which the 
arrangements for the Annual Meeting in the summer were 
discussed. It was finally determined to make a change in 
the method of holding the Meetings, so as on the one hand 
to diminish the labour and also the pecuniary risk for the 
Society of the town where the Meeting is held, and on the 
other to make the programme more suitable to the wants 
of those members who can only spare one day to the 
Meeting, and of those who can attend the whole, as well as 
of those who coming from the longer distances yet do not 
wish to give up the whole of two days. It is therefore 
proposed that on the afternoon of the first day of the 
Meeting there shall be an opportunity for seeing the local 
objects of interest; that the business meetings shall take 
the place of the Conversazione in the evening, and that the 
Excursion or Excursions on the next day shall start at such 
an hour as shall permit of the members who live near 
taking part in them, and yet shall get back in time for the 
visitors to get away by evening trains. 
It will be seen that the labour for the local Society is by 
this means reduced to the very small amount necessary to 
arrange an interesting route for an excursion and to order the 
vehicles.
