Here we have a true gum, without so much as a trace of resin. 



Following is the evidence the author has been able to collect in 

 regard to the exudation of the Indian tree. 



" It yields a resinous gum " (Cat. Kew Museums). Perhaps the 

 experiments of von Essenbeck (infra) are the foundation for this 

 statement. 



" It is called bastard cedar from an aromatic (sic) resin 

 exuding from it, resembling that of the American Cedar " (Art. 

 Cedrela Toona in Surgeon-General Balfour's Cyclop, of India). 

 No definite authority is given for this statement, and the writer is 

 probably labouring under a misapprehension, as the name Cedar 

 was bestowed in reference to the wood, and not to any exudation. 



The experiments of Nees von Essenbeck, who extracted from the 

 hark a resinous astringent matter, and a brown astringent gum^ do 

 not affect the point at issue one way or the other. 



" Toon-ke-gond " (C. Toona) is enumerated by Dr. Wight as 

 one of the gums of Coimbatore. Yet Cooke (Gums and Resins of 

 India) who quotes this statement, says, " From the character of 

 the timber one might suppose it rather a resin than a gum." I 

 am not impressed with the force of the latter observation. 



A sample of " Toon-ke-gond," the exudation of C. Toona, was 

 exhibited by Dr. Royle at the Exhibition of 1851 (No. 52, p. 180, 

 Jury Reports). It is not definitely stated whether it is a gum or 

 a resin, and there is nothing in the context to clear up the point 

 absolutely.
