The Council have to announce the completion of the first volume 

 of the Society's * Transactions ' and the commencement of the 

 second, two parts of each having been published during the year. 

 The publication of so much matter has added considerably to your 

 expenditure, but the large number of members who reside at too 

 great a distance from Watford to attend the meetings or derive any 

 benefit from their membership besides the receipt of the ' Trans- 

 actions,' seems to be a sufficient justification of the endeavour to 

 give as complete a record of the proceedings of the Society as 

 possible. 



For the illustrations which have appeared in the first volume of 

 the ' Transactions ' the Society is in most cases indebted to the 

 liberality of authors, Mr. Lobley having provided the woodcuts 

 illustrating his lecture on the Cretaceous Rocks of England ; Mr. 

 Pryor the map of Hertfordshire showing his proposed botanical 

 districts ; and Mr. Harford the plate illustrating his lecture on the 

 Polarisation of Light. To the Dii^ector of the Geological Survey 

 of England, and the Council of the Geological Society of London, 

 the Society also is indebted for the woodcuts illustrating the 

 lecture by Professor Morris on the Physical Structure of the 

 London Basin.
