that work fell short of accomplishing Mr. Watson's design. It ap- 

 peared from these tables that the 33 Local Floras and Catalogues 

 consulted by Mr. Watson (besides being for the most part very im- 

 perfect in themselves) only partially represented the vegetation of 1 8 

 out of the 42 districts above-mentioned ; and that with respect to 

 the remaining 24 districts, his work had left us entirely in the dark. 

 It further appeared, with regard to the districts represented by the 

 12 Floras and 19 Catalogues referred to by Mr. Watson, — extend- 

 ing (though by interrupted lines), the former from Devonshire to 

 Edinburgh, the latter from Sussex to Orkney, — that out of 1220 

 species noticed in them, 317 occurred in all the Floras, and 156 

 were confined to one or other of them ; and that 78 species occurred 

 in all the catalogues, and 152 were peculiar to one or other of them ; 

 whilst, on the other hand, in the Floras only 64 species, and in the 

 Catalogues only 50 species were peculiar to the mec?zMm numbers re- 

 spectively; thus showing according to Mr. Brand's view a remarkable 

 tendency in species to accumulate (as respects their frequency) to- 

 wards extremes — that is to say, to be either very generally or very 

 partially distributed over the country. On these and similar data, 

 supported in some degree by other circumstances which he explained, 

 Mr. Brand calculated that, allowing nearly 4000 for varieties, about 

 30,000 specimens would suffice for completing a British Herbarium 

 on the plan which he proposed, requiring probably about 5000 leaves 

 of paper. 



The thanks of the Society were given to Mr. Brand for the labour 

 bestowed in the preparation of this paper, and the valuable tables 

 which it contained. 



2. Mr. Forbes read an account of an excursion to the mountains 

 of Ternova in Carniola, in company with Signor Tommasini of 

 Trieste. They left Goritzia about the middle of June last, and pro- 

 ceeded to Chapovano by way of Monte Santo, gathering the true 

 Athamantha Matthioli on the banks of the Izonzo, with several other 

 plants of much interest. At Chapovano they ascended the Stoddier, 

 thence they proceeded through the forests to the mountain of Boda- 

 nowitz, and on the third day ascended the Golaks, the highest moun- 

 tains of the chain, being about 5800 feet above the level of the sea. 

 Among the plants collected during the excursion, were Lilium car- 

 niolicum, Hieracium incarnatum. Campanula carnica, C spicata, Cyti- 

 sus angustifolius, Aquilegia Sternhergii, Polygala austriaca (new to 

 the district), P. alpestris, Pleurospermum Golaka, Spartium radiatum, 

 Paederota Ageria, Carex firma and tenuis, Euphorbia carniolica, Pri- 

 mula carniolica, Uacquetia Epipactis, Astrantia carniolica, Gentiana
