L. Weights and Measures. Miscellaneous Notes. 



Weights and measures and values of exchange present 

 difficulties when summarising the information contained in 

 the agricultural and scientific press of some countries. Scien- 

 tific publications generally make use of the decimal metric 

 system and measure temperatures by the centigrade scale. 

 But farmers are unwilling to change the systems to which they 

 are accustomed; and in agricultural experiments, especially 

 in some countries, data are generally reckoned in accordance 

 with the old prevailing local usage. 



For the sake of comparison it would be desirable that all 

 measures and values be converted to that metric and monetary 

 system which France, with justifiable pride, dedicated " to all 

 ages and all peoples." In many cases this will be done; but 

 as the original figures will always be given, brevity and the 

 fear of overloading the pages with numbers, will often compel 

 us to give the original data only, converting into the metric 

 system the more important and conclusive figures. Tables of 

 reference and coefficients of reduction, for converting measures 

 and values into the decimal metric system, will be given in 

 those Bulletins where such information is required. 



Translating from the periodical press and from books and 

 reports written in many different languages, mistakes may 

 easily be committed in the names of plants and their diseases, 

 and in the names of insects, of allied pests, and of other ani- 

 mals. In the case of scientific names, whether botanical or 

 zoological, efforts will always be made to verify them by 

 trustworthy books of reference: for instance, in the case of 

 flowering plants, by the Index Kewensis. Unfortunately, such 

 complete and handy nomenclators as this Kew Index, due to
