Medbllosa. — Those who study fossil botany seem rather to work 

 from a morphological than a systematic standpoint. Hence such 

 works as Mr, Arber's " On the roots of Medullosa anglica " (Ann. of 

 Botany, xvii) are of not infrequent occurrence. The first British 

 specimens of Medidlosa, one of the Palaeozoic Cycadofilices, were 

 described by Dr. Scott as recently as 1899. From sections of the 

 roots of this plant, preserved at Cambridge, and. which Mr. Lomax 

 considers came from the Lower Coal-measures of Hough Hill 

 Colliery, Stalybridge, Lancashire, Mr. Arber has been enabled to 

 supplement Dr. Scott's very complete account. The result of this 

 examination of fresh material has revealed a more complete know- 

 ledge of the thin-walled tissues which lie between the xylem and 

 the periderm. The most noteworthy points are, the presence of 

 a thin zone of phelloderm, the structure of the phloem, and the 

 discovery of lateral sieve-plates in the phloem elements of both the 

 stem and the roots. In the phloem of Medidlosa we have another 

 point of agreement between it and Seterangium. The structure of 

 the root of Heterangium tiliceoides is at present unknown, but the 

 phloem in the roots of Medullosa anglica closely resembles that of 

 the stem in the former species. Excellent figures are given. 



Peru. — Under the authority of Don Eugenio Larrabure y Unanue, 

 Minister of Foreign Affairs in Peru, Mr, Eduardo Higginson, Consul 

 of Peru, has issued a new map of the republic. This is not in any 

 way geological, but will be found of great value by those who seek 

 to localise specimens from that interesting country. The back of the 

 map contains much printed matter of interest, and that relating to 

 geological matters will be found under the heads of Guano, Artesian 

 Wells, and Mineral Wealth.

Annual General Meeting, June 26th, 1903, — Dr. Henry 

 Woodward, F.R.S., President, in the chair. The Secretary read 

 the fifty-sixth Report of the Council for the year ended 31st March, 

 1903. It referred to the satisfactory condition of the Society, and 

 the unusually large volume, with varied contents, which had been 

 issued for the year 1902. This volume contained instalments of the 

 monographs of Pleistocene Mammalia (Cave Hyaena), Cretaceous 

 Fishes, Cretaceous Lamellibranchia, and Graptolites. The receipts 

 were £91 3s. 5d. less than those of the previous year, and there had 

 been several losses by death and resignation. Special reference was 

 made to the death of the Rev. Thomas Wiltshire, D,Sc., who was for 

 thirty-seven years Secretary of the Society. The withdrawal of 

 several small libraries was noticed, and an appeal was made for 

 new personal subscribers. Besides the monographs of Cretaceous 

 and Carboniferous Mollusca, Graptolites, Cretaceous and Carboni- 

 ferous Fishes, and Pleistocene Mammalia, other works were also 

 in active progress, among these monographs of Trilobites and
