3. SUMMARY OF THE DATA FOR THE AVERAGE PERCENTAGES OF PHOS- 

 PHATIDE AND CHOLESTEROL. 



4. CONCLUSIONS FROM THE DATA FOR THE CHOLESTEROL AND PHOS- 

 PHATIDE CONTENT. 



(a) The content of phosphatide decreases in the different types in the 

 order named: indifferent, hemolytic, green-producing. 



(b) The same relation is noticed in the amounts of cholesterol contained 

 in the different organisms. 



(c) The ratio C:P increases when the types are listed in the same order.
