SESSION 1906-1907. xxxix 



St. Albans, after the Rothamsted field meeting, and to Mr. and 

 Mrs. Mawley, at Berkhamsted, for their kindness in receiving or 

 entertaining the members at the above meetings ; also to Dr. and 

 Mrs. Morison for receiving and entertaining the members and 

 friends at the conversazione, and to Mr. and Mrs. A. E. Gribbs 

 for arranging the programme of music on that occasion. 



The twelfth volume of the present series of the Society's 

 ' Transactions ' has been completed during the year by the issue 

 of three parts containing 88 pages and one plate. The volume 

 consists of 344 pages with 30 text-illustrations and 7 plates. To 

 the topography of the county the only contribution in it is the 

 third instalment of the Catalogue of Hertfordshire Maps, which 

 comprises 40 pages with a folding plate. The meteorology and 

 phenology of the county are treated of in seven papers, the 

 usual annual reports ; to the geology three are devoted, one on 

 the gravels of Hertfordshire and two on Post-Pliocene beds 

 temporarily exposed at Watford and near Hunton Bridge ; on 

 the botany there are two papers, one on climbing and twining 

 plants in the South Midlands, the other on the rate of growth of 

 two species of oak at Bayf ordbury ; and on the zoology there 

 are twelve papers, three being the usual annual reports on our 

 Lepidoptera, and four others being entomological, three the 

 anniial reports on our birds, one a- review of Hertfordshire 

 ornithology, and one on Hertfordshire Mammalia. A paper on 

 a Neolithic celt is the only contribution to the archaeology of the 

 county. One of the Presidential Addresses is of local interest, 

 adding to our knowledge of the early Hertfordshire naturalists. 

 Of 32 papers in the volume there are thus 27 which give the 

 results of local investigations. The ' Proceedings ' cover a period 

 of two years and a half (January, 1903, to July, 1905), and 

 include the annual reports of the British Association Conferences 

 of Delegates of the Corresponding Societies. 



The Society is indebted to Mr. B. Daydon Jackson for a 

 donation which more than covers the cost of illustrating his 

 Address on the History of Botanic Illustration ; to Mr. Vernon 

 Kitchin for the block used for Plate IV ; to Mr. Fordham for 

 that used for Plate V ; to Mr. Hopkinson for those used for 

 Plates VI and VII ; and to Sir John Evans, Mr. Lewis Evans, 

 and Mr. Fordham for the figures in the text illustrating their 

 papers. 



The usual exchanges with other Societies have been made and 

 several other works have been added to the library. 



The Barnet Natural History Society and Field Club has 

 become afiiliated to the Society on terms approved by the 

 Council, and it is hoped that co-operation with this yoimg and 

 vigorous organization and its energetic Secretary, Mr. C. G. 

 Kiddell, will result in benefit to both Societies. 



The Council regrets that, in order to meet the increasing 

 deficit of recent years, it has been necessary to sell India stock 

 held by the Society to the amount of ^30, reducing the invested
