tracks, has a mortality of only 1.8, but Hawaii is relatively 

 high, with 7.2." 



Referring to the mortality map showing the distribution 

 of exophthalmic goiter during the decade 1920-1930, Petersen 

 states, "This is so characteristic that it deserves emphasis. 

 Region I has Oregon as the focal point, then lower rates 

 occur in the dry highlands of the Northwest but along the 

 southern fringe of the cyclonic tracks (Colorado, Kansas, 

 Missouri) an accentuation occurs until we come to the 

 region of the Lakes (2) and now we find Ohio as the focal 

 point. The high rates actually begin with Minnesota, 

 Ontario, Wisconsin, and Illinois. Again the northeastern 

 states are spared, and New Hampshire and Maine show a 

 low mortality. 



"And the Negro, as he moves north into the turbulent 

 atmosphere, becomes ill with exophthalmic goiter. 



"In Newfoundland exophthalmic goiter is practically 

 non-existent, and in Hawaii, too, the mortality is only 0.8 

 for 100,000 inhabitants." 



Of cardio-vascular-renal disease, Petersen says, "Heart 

 disease leads as the cause of death. It is estimated that 

 there are some two million people in the United States who 

 are so afflicted. But unfortunately, our statistical material is 

 by no means satisfactory. . . . When we examine the map 

 for deaths from heart disease for a single year we find the 

 storm tracks clearly outlined. New Hampshire is high with 

 a rate of 323 (per 100,000) approximately three times as 

 many deaths from heart disease as is shown for Arkansas. 

 The statistician examining this distribution will be inter- 

 ested primarily in observing that the rate is a reflection of 

 the old-age grouping." 



It is interesting to contrast Petersen's maps of the in- 

 cidence of the various diseases of civilized man with 

 his map showing the distribution of variability of tem- 

 perature for 1925. 



Of arteriosclerosis instability, Petersen says, "There can
