170 On the Cultivation of Tea in the 



mixtures of neutral and acid combinations of chlorous acid, with C'^^ 

 H-'' N^ 0^^, and a variable quantity of hyposulphurous acid. 



All these chlorites dried over sulphuric acid at the ordinary tem- 

 perature, appear white and pure. They have all ihe same proper- 

 ties, and tend to confirm the doctrine of protein. 



As we must distinguish between chlorite of protein with hyposul- 

 phurous acid, and chlorite of albumen, fibrin, &c., we must do so 

 also with their other combinations. 



Thus, we must call the compound, which I have formerly ana- 

 lysed,* tannate of albumen. It consists of — 



=r(C-^ H25 N^ 0^« + (04 S N H^) + H 0) + (C^^ H'^ 0^ + 2 H 0) ; 

 that is, albumen with tannic acid, which has exchanged one equivalent 

 of water for one equivalent of albumen. You see, that this formula 

 agrees also better than the former with my old results. The same 

 applies to sulphuric acid with albumen, and sulphuric acid with pro- 

 tein. 



When protein containing hyposulphurous acid is dissolved in strong 

 sulphuric acid, the former is expelled and replaced by the latter, in 

 a quantity amounting to 5 per cent. 



In my following communications to you, I hope to treat of these 

 and other combinations. 



Believe me, 



Yours faithfully,

Important Information regarding the Cultivation of Tea in the 

 Valley of the Dhoon, India, 



The last Calcutta Gazette contains a very important dis- 

 patch from the Court of Directors, relative to the capabilities 

 of the Valley of the Dhoon, and the adjacent districts, for the 

 production of tea. Several valuable reports have recently 

 appeared in the local journals of the success which has at- 

 tended the efforts of Dr William Jameson (nephew^ of Pro-
