' Same as No. 53, with the addition of two months' observations at other islands. 



^ These results are obtained from observations for nine months at Barbadoes, three months at Porto Cabello, Vene- 

 zuela, one month at Chagres, New Grenada, and twenty-six days at sea near the coast. 



^ The mean directions are copied from Professor Loomis's article in the Journal of Science and Arts. The puinbers 

 in the columns headed " Rate of Progress," express the ratio that the resultants bear to the sum of the winds, after being 

 resolved in the direction of the cardinal points, and are somewhat less than if they had been computed from the original 

 observations.
