Ethyl Ether. 



Solubility in water at 15° C 8 per cent. 



„ serum „ 11 „ 



At 10 per cent, and over in the serum there was a slight opalescence, and 

 the fluid began to grow gelatinous ; 11 per cent., completely dissolved ; 12 per 

 cent, not dissolved; and at higher percentages two phases separated, the layer 

 on top forming a clear, thin jelly. 



Ethyl Acetate. 



Solubility in water at 15° C 7"9 per cent. 



„ serum „ 10 „ 



At 8 per cent, complete solution of the ethyl acetate and commencing 

 precipitation of the proteid occurred. Solutions of 9 and of 10 per cent, 

 strengths also dissolved completely. Separation into two phases occurred at 

 12 per cent., the upper layer being viscid. 



Amyl Alcohol. 



Solubility in water at 15° C 2*4 per cent. 



„ serum „ 8 „ or over. 



At 3 per cent, complete solution of anaesthetic with commencing precipita- 

 tion of proteid. This precipitation gradually increased with concentrations of 

 3 - 5 and 4 per cent, up to 8 per cent., when a thick cream was formed. A 

 separation into two phases could not be observed at any stage. 



Amyl Acetate. 



Solubility in water at 15° C 0*25 per cent. 



„ serum „ l - 5 „ 



At 1 per cent., complete solution of anaesthetic with precipitation of proteid ; 

 at 1*5 per cent., all dissolved except a few minute globules. 



Benzol. 



Solubility in water at 15° C - L5 per cent. 



„ serum „ 0"6 „ 



At 0*5 per cent., commencing precipitation and opalescence ; 0*6 per cent, 

 completely dissolved ; - 7 per cent., not all dissolved. 



Xylol. 



Solubility in water at 15° C 0-016 per cent. 



„ serum „ 0-2 „
