The fluid was slightly bloody, and on standing deposited a 

 yellow sediment. 



2. In a case of metroperitonitis and bronchopneumonia there 

 was found in the abdomen a reddish-yellow fluid which de- 

 veloped a little sulphuretted hydrogen, had a well-marked acid 

 reaction from the presence of free lactic acid, and coagulated 

 perfectly on heating. The fluid separated from the coagulum 

 by filtration had an acid reaction, was of a yellow colour, and 

 contained much extractive matter in solution. On warming it 

 with carbonate of zinc, filtering, and evaporating, crystals of 

 lactate of zinc were readily obtained.
