IV PREFACE 



In 1935 the following letter was received from Dr. Hesselberg, 

 president of the International Meteorological Committee : 



Mr. H. H. Clayton. 

 Dear Sir, 



It is a great pleasure to mc to notify you that the Conference of Directors of 

 Aleteorological Services at Warsaw has expressed — on the proposal of Sir 

 George Simpson, President of the Commission for the Reseau Mondial of the 

 International Meteorological Organisation — its appreciation for the work you 

 have accomplished together with Mr. Roebling in preparing the edition of World 

 Weather Records. 



The Conference expressed its thanks to you in adopting the following 

 Resolution : 



"The Conference wishes to express its sense of obligation to Mr, H. H. 

 Clayton and Mr, John A. Roebling for the publication of the valuable series 

 of meteorological data contained in the two volumes of World Weather 

 Records. These data have already been of great use to investigations of 

 world climate and form a mine of information for future investigation," 



I am very happy to communicate this Resolution to you and to congratulate 

 you with the success of your work. 



Yours faithfully, 



Th, Hesselberg, 



President, International 

 Meteorological Committee.
