Architectural experts and shipbuilders evinced a greater interest. 

 H. DE Bruyn asserted in 1851 that djali kapiir is considered to be 

 of the least quality, "on account of the calcareous secretions found 

 in it". ') A little more is said by C. G. von Dkntsch, when he tells 

 us that "the tree is named after the veins of sulphuric acid lime, 

 which aie often visible over the whole length of the stem and seem 

 to be owing to the lime particles ascending with the saps" *). Two 

 years later F. Junghuhn called attention to the fact .that those secre- 

 tions were restricted to the specimens of Tectona growing on lime- 

 marl deposits, such as are found especially in the residences of 

 Renibajig and Surabaya'). Some geologists disagree as to the nature 

 of these secretions. Whereas von Dentzsc:h takes them to be calcium- 

 sulphate, Herman Crügkr (1857) holds that ''Tectona </mmILs" is 

 "nach ihrem durch das iVIikroskop bestimmbaren Gehalt an Kiesel 

 eine schwache Kieselpflanze", but he omits telling us how he could 

 establish the presence of siliceous particles. He also fancie<l he had 

 observed "dass die Zellwande von kohlensauren Erden eingenommen 

 und sicii zwischen grossen Kieselkörpern ohne bestimmbare Formen 

 befinden" "j. Subsequent investigators have not detected this either and
