Liquid Kino. 83 



It has a specific gravity of 1"00S at GO°F., and an acidulous 

 smell (owing to the presence of acetic acid), accompanied by 

 an odour not so pleasant, and reminding one somewhat of 

 spent tan liquors. It deposits a quantity of sediment of a 

 buff colour, consisting almost entirely of catechin. It 

 contains tannic acid "772 per cent., " non-tannin " 'oOS per 

 cent. (Lowenthal's process.) The water amounts to no less 

 than 98-3 per cent. The catechin was not estimated in this 

 sample. 



2. This was obtained from Cambewarra, but from a 

 different locality. It is darker in colour than the preceding 

 sample, being of a rich ruby colour. Like No. 1, it deposits 

 a small quantity of sediment (catechin). This liquid kino 

 had a specific gravity of 1'022 at GOT., when received in 

 April 1888. 



The followino- results were obtained in December to 

 January 1889: — Tannic acid 3'048 per cent, (of the liquid 

 kino, without evaporating), "non-tannin " 1*27 per cent, (a 

 portion of liquid kino, kept in agitation so as to obtain a 

 fair proportion of sediment, was added to water to make up 

 the strength of one grain of liquid kino to the liti-e), water 

 9(i"7 per cent, (after filtration from deposited catechin). Tlie 

 catechin and a little phlobaphene filtered off", were found to 

 be in the ])roportion of •495 per cent, of the original liquid 

 kino. Ether agitated with the filtrate took up 15 per cent., 

 of which one-third was estimated to be catechin, and the 

 rest resin. 



Mr. Kirton has recorded liquid kino from the lUawarra 

 district of New South Wales, but since there appears to be 

 no reason why it should be found in one colony more than 

 another, it will doubtless also be obtainable in Victoria, 

 most likely on application to fishermen.
