XIII, A. 6 King: Philippine Coir arid Coir Cordage 287 



As presented by Prudhomme only thirteen tests are included, 

 the English values having been converted into the correspond- 

 ing metric ones and, in addition, the title of the table changed 

 to read as if Roxburgh's experiments had been conducted on 

 cords of the same size. The size of the cords is not mentioned 

 in the table quoted by Royle, from whom Prudhomme obtained 

 his data through M. Lecomte. 



Copeland still further condenses Roxburgh's data by omitting 

 thirteen of the twenty-one fibers and by dropping the tests on 

 tanned and tarred specimens. He fails to state that the fibers 

 were tested in the form of cords, and neglects to include the 

 lengths of the specimens tested ; nor does he state where his data 

 were obtained. 



Wight's results on the comparative strength of coir rope are 

 quoted more frequently than Roxburgh's, and often constitute 

 the only numerical data accompanying an article on coconut 

 fiber. The former results are cited in several different ways 

 by Spon,=' Watt,'" Vetillart,^^ Mitchell and Prideaux,^- Dodge," 

 and Matthews." Royle ^' gives the following as the results of 

 Doctor Wight's experiments : 



Pounds. 



Coir 224 



Pooley Mungee {Hibiscus cannabinvs) 290 



Marool (Sanseviera zeylanica) 316 



Cotton {Gossypium herbaceum) 346 



Cutthalay nar {Agave americana) 362 



Janapa (Crotoktria juncea) , Sunn, hindee 407 



Yercum {Calotropis gigantea) 552 



Some of the designations are in the Indian vernacular. Ac- 

 cording to this table coir is the weakest of the seven fibers tested ; 

 in another place Royle "* restates a part of the same data, but
