3- The geological formation most favorable to the multiplication and 

 development of any species. 



4. Dimensions of remarkably developed specimens of any species. 



5. The common or local name of any species in addition to those 



already given. 



6. The purposes, however unimportant, for which the wood of any 



species is employed. 



7. Products of any species other than wood, such as tannin, char- 



coal, dyes, potash, edible fruit, forage, etc. . 

 3. Catalogue of Trees and Shrubs^ native and introduced^ in the 

 Horticultural Gardens adjacent to Horticultural Hall in Fairmount 

 Park, Philadelphia. — The purpose of this catalogue seems to be in 

 part to furnish the visitors to the Park with some means of determ- 

 ining the names of the trees and shrubs which attract their observa- 

 tion. In consequence the arrangement is not strictly scientific, and 

 the names are frequently those popular with gardeners in preference 

 to the less known botanical denominations. The need of some 



guide to the name and character of the plants cultivated in places of 

 public resort is obvious, if any educational purpose is to be served 

 by such collections. But the plants should be conspicuously labelled, 

 for the ordinary visitor has but slender opportunity to determine the 

 botanical position of a tree or shrub whose acquaintance he desires 

 to make. The Club made some effort to have this labelling done 

 for Central Park, but without pushing the matter through. This cat- 

 alogue will no doubt prove a great boon to those of the Philadelphia 

 public who interest themselves in the vegetation of their noble park. 

 4. The Bartram Oak, by Isaac C. Martindale, read at the annual 

 meeting of the West New Jersey Surveyors' Association, at Camden, 

 ist month 6th, 1880. In this interesting monograph of 24 pages 

 Mr, Martindale has collected all the references to this much dis- 

 cussed oak. The typical specimen described by Michaux, found 

 by him m a field belonging to Mr, Bartram, has long since been 

 destroyed. The trees on the Bartram place which have been accred- 

 ited as seedlings of the original, and have probably on this account 

 contributed much to the doubts about its being a true species, are 

 here supposed to be seedlings of Quercus Phellos and not of the origi- 

 nal tree. Other specimens have been found growing wild up and 

 down the Delaware, and, it is believed, in North Carolina and Texas. 

 Mr. Martindale, upon a review of all the evidence and a personal 

 knowledge of a number of the trees, is strongly of the opinion that 

 Quercus heterophylla^ Mchx., is a distinct species. 



5. Catalogue of North American MuscL arranged by Eugene 

 A. Rau and A. B. Hervey, A.M. This catalogue is desicrned to be 

 a convenient check and exchange list and a basis for arrangement 

 of genera etc., in herbaria. ^ The classification is mainly that 

 adopted by Prof. Schimper m his Synopsis of European Mosses. 

 All the authentic species and varieties reported from Mexico to 

 the Arctic regions have been included, and their habitats given with 

 as wide a range as the examination of references and several good 

 herbaria would permit^ The compilers acknowledge particular in- 

 debtedness to C. H. Peck. C. F. Austin and Chasf Moh It m^^^
