Seeds in Petrels 



Darwin, in his correspondence (1859) with Sir Joseph Hooker, refers 

 to the occurrence of large West Indian seeds in the crops of some nestling 

 petrels observed by Sir William Milner at St. Kilda {Life and Letters, 1 1 . 

 147, 148). Mr. Charles Dixon in Ibis (1S85) refers to Sir W. Nfiln< 

 observation in the case of the Fulmar Petrel (Procellaria glacialis) and 

 speaks of them as Brazilian seeds brought by the Gulf Stream, adding that 

 he himself found a nut in the crop of one of these birds in the sam< 

 locality. He supposes that the birds pick them up from the wal 

 Mr. Hemsley very kindly wrote to Sir Joseph Hooker recently on this 

 point with the object of obtaining some idea of the nature of the seeds ; 

 but after this lapse of time it has not been found possible to sat 

 my curiosity. I live in the hope of their proving to be Caesalpinia

Schimper on the Halophilous Character or Littoral 

 Leguminos/e and of Shore Plants geni rally 



As a result of extensive microchemical investigations, this eminent 

 German botanist arrived at the conclusion that plants living on the S( 

 shore, or in inland stations rich in chlorides, are able, as a rule. . up 



in their tissues a large quantity of these salts, a capacity enabling them t<> 

 live in localities where the subsoil is rich in these material-. This inf< 

 as shown in his experiments, is just as applicable to the shore-plants 

 of temperate regions, such as Aster tripolium, Crambe maritimum. and 

 Eryngium maritimum, as it is to such typical littoral plants oi the troj 

 as Barringtonia speciosa, Ipomea pes capraj, Scaevola Koenigii, roumefortia 

 argentea, &c. However, with the Leguminosse experimented upon, this 

 capacity of storing up chlorides was often exhibited but slightly or not 

 all; and characteristic Pacific beach-plants, such as Canavalia turgida, 

 Pongamia glabra, and Sophora tomentosa are esp 1 ially cited as exampU 

 (Schimper's Ind. Mai. Strand-flora, pp. 140-151 j Wolffs ash-ana
