WHERE EXTRACTS ARE PREPARED: Here, in the laboratory of the L. Dell Henry clinic, extracts of varied dusts and pollens are prepared in liquid form. They will be injected into the patients. One bottle of pollen, like the one held by Leonard Dolan, laboratory technician, may contain more grains than would be found in the entire state.
