Alabama. — The Alabama Agricultural Experiment Station determined the 

 vitamin A potency of butter made on farms in the State. The samples were 

 collected from retail markets in Alabama. Drought conditions in the summer 

 of 1943 probably affected the potency of all the butter produced in the State 

 in that year. The results, corrected for loss in analysis, are given below:

Texas. — The Texas Agricultural Experiment Station determined the vitamin 

 A potency of 62 samples of market butter sold in Texas in 8 different months 

 in 1942 and January 1943. The study was started prior to and independently 

 of the present Nation-wide survey, and the method of analysis was different. 

 But allowing for this difference in analytical methods, the monthly averages 

 compare favorably with the averages for the creamery butter studied in such 

 States as Wisconsin, Minnesota, Iowa, and others.
