463 Dr. Anderson on the Products of the 



filled with small shining scales. The analysis of this salt, 

 dried at 212°, gave the following results : — 



6*970 grs. of plantinochloride gave 3'392 carbonic acid and 

 2*434 water. 



6*475 grain's of the salt gave 2*422 grs. platinum. 



8*257 ... ... 3*047 



10000 265*2 



From these results we arrive at the formula C^H^.N, HCl,Pt CI*, 

 which is that of the platinum salt of a base C^ H^ N. The 

 base is therefore the substance I have before described* as a 

 product of the action of alkalies upon codeine, under the name 

 of Metacetamine, but which I now prefer calling Propylamine, 

 in accordance with the name now usually applied to the acid 

 with which it corresponds. Unfortunately the quantity of 

 propylamine obtained was too small to admit of my examining 

 either its compounds or itself with accuracy. It is, however, a 

 perfectly limpid and colourless fluid, with a strong pungent 

 odour resembling that of petinine, but more ammoniacal. It 

 gives an abundant white cloud when a rod dipped in hy- 

 drochloric acid is brought near it, and unites with the con- 

 centrated acids, with the evolution of much heat. Its hydro- 

 chlorate crystallizes in large plates closely similar to those of 

 methylamine and petinine. 



The discovery of methylamine and propylamine among these 

 products naturally directed my attention to the probable pre- 

 sence of ethylamine, the intermediate term of the same series; 

 but as I had not employed any very particular precautions in 

 condensing the more volatile products during the successive 

 rectifications to which I had subjected the crude oil, almost the 

 whole of it appears to have escaped. By collecting, however, the 

 first few drops passing over in the rectification of the portion 

 boiling under 150° in hydrochloric acid, and forming a platinum 

 salt, I obtained the following result : — 



6930 gi-s. of platinochloride gave 2*649 grs. platinum. 



This corresponds to 38*22 per cent. Now the per-eentage 

 of platinum in the ethylamine salt is 39*60, and the result
