CONCLUSION 
The transformation of pseudoglobulin into euglobulin was observed in 
four serums that had been heated 30 minutes at 6o° C. in the presence of 
30 per cent saturation ammonium sulphate. In some instances the 
amounts transformed were considerable, although in one of the serums 
the amount was so small as to indicate that the transformation does not 
take place in all serums. 
The methods of analysis were improved by the use of the centrifuge 
as a means of separating globulin precipitates from their filtrates. The 
precipitations in the analyses were made at the same dilutions as in the 
precipitations of globulin for therapeutic use.
