THE BOTANISTS OF PHILADELPHIA. 327 



" Beyond any statement of the money value of the her- 

 barium, its true value will be in its importance to scientific 

 study and future investigations. Mr. Martindale's studies 

 brought him in contact with the botanical teachers and 

 authorities, and numerous are the specimens bearing the 

 labels of such eminent botanists as Dr. Asa Gray, John M. 

 Coulter, Sereno Watson, Dr. N. L. Britton, Professor E. L. 

 Greene, Dr. Vasey, Professor Macoun, Professor Underwood, 

 Dr. Porter and William Canby. 



" The specimens and various genera or orders, difficult 

 of determination, have been very generally submitted to 

 specialists in the various departments, and their notes and 

 reference will add materially to the value of this collection. 

 Many of the composites were examined and determined by 

 Dr. Gray while preparing the volume of his Synoptical 

 Flora of North America, covering that order. 



" In the catalogue of the plants of New Jersey, forming 

 part of the geological survey of that state, Professor N. L. 

 Britton frequently refers to the herbarium of Mr. Martin- 

 dale as authority for statements made." 



It is the intention of the Philadelphia College of 

 Pharmacy, to whom the herbarium was presented through 

 the liberality of Messrs. Smith, Kline, French & Company, 

 to preserve the Martindale Herbarium intact as a reference 

 herbarium, and, under proper regulations, it will be open to 

 visiting botanists for study and consultation.
