 these blank forms will be better understood 

 by reference to Fig. 3, which is engraved 

 directly from one of the pages. I,t is con- 

 siderably reduced in' size, however, the orig- 

 inal page measuring 6 x 9^ inches. Such a 

 laboratory note-book has certain advantages 

 as well as several disadvantages. 



It should be noted that the making of ac- 

 curate descriptions is much a matter of ex- 

 perience. The beginner will find it slow 

 work, and many of his entries will be made
