Entries 56 ~ 72 I dropped the "x" (I figured that "dx" was akin to "rx", I am happy that I was correct, based on your answer to "soll's" query) I also feel that the Erlenmeyer flask works better than the microscope as a means of indicating "lab" and is simpler and easier on the eyes - if you prefer the font from entry
#25 over the newer font used I could upload a new version.
Thanks
