Jany 26th. 1899 R.R. Bowker Esq. Delano and Elm Street New York My Dear Bowker:- In reply to your favor of the 24th inst, I beg to state that of course I want all the criticisms possible. With new [meter] you leave the months reading standing until the next month, after reading the customer can see what his bill is. If by any accident the Mercury should go in the check bottle it can be [confined] and placed in a tube and read off directly. The last beam Meters were constructed with Mercury Electrodes, but you have mechamism and meters with mechanism can ever be made as [perfect] as those without. Verification is absolute in the meter I now [have]. I also have an index meter which instead of showing a mercury column shows reading on a six inch index, [but you] have mechanism. Yours very truly
