Two years ago this committee recommended to the Society a 

 new descriptive chart in the form of a folder. The folder was 

 intended primarily for use in instruction, although it was felt 

 that it might be satisfactory in some forms of research work. 

 When first brought to the attention of the Society, this chart 

 provoked much discussion, and it was finally decided that the 

 only way to determine its value would be to print it and test it by 

 use in a practical way. Hence the chart was not officially 

 adopted by the Society, but the committee was directed to have 

 it printed and to distribute it. At the present time the commit-

 this chart. In the first place, the orders that are constantly 

 being received for it, many of them repeat orders, have endorsed 

 it sufficiently; and in tne second place, we hope to draw up a 

 new chart during 1920 embodying some of the suggestions that 

 have been made while the folder has been in use. During the 

 half of 1918 in which tne folders were on sale, 10,000 were sold, 

 and during the last year 8000 — a total of 18,000. Meanwhile 

 during these same eighteen months, only 4400 of the old charts 

 have been called for. 



The extent to which the new chart has been purchased shows 

 that it is generally preferred to the old single page chart. This

 laboratories, and the folder was designed primarily for instruc- 

 tion. It is still in need of revision, however. Besides various 

 matters of detail that need changing, three fundamental ques-
