Dear Sir:
I return herewith bills Feb 1st 105.15/xx and $15[7]5.13. The former is the Carbon filament experiment for January and labor in the latter is divided as follows
Labor on machine for sealing carbons in bulbs. 669.09
Test Room 437.26
General Lamp Experiment 70.15
$1176.50
The fixed charges of the laboratory are distributed over all experiments and based upon the labor. These charges are included in the above amounts. If you desire further details perhaps an inspection of our books would be more satisfactory to you in which case we will be pleased to open them for you at any time.
Yours truly,
A.O. Tate
