ACKNOWLEDGMENTS 



I am indebted to the former Chief of the Argentine Weather 

 Service, jMr. G. O. Wiggin, and the present Chief, Mr. F. Burmeister, 

 for encouragement given, to Mr. H. H. Clayton, the founder of the 

 weekly weather forecast, to Dr. C. G. Abbot and his assistants, 

 Messrs. Aloore, Abbot and Aldrich, to Mr. E. Wolff, Chief of the 

 Pilar Magnetical Observatory, and to the Director of the La Plata 

 Astronomical Observatory, and their respective staffs, all of whom 

 have assisted the weekly weather forecast and without whose help it 

 would have been impossible to produce it.
