Title
[D8846AAK], Letter from Dyer and Seely to Thomas Alva Edison, February 27th, 1888
Editor's Notes
"These three cases in inventions belonging to the Light Co. have been allowed by the Patent Office. ### Case 379, on spiral filamentation series, coiled one within the [unclear] so as to increase the resistance and reduce the [unclear] radiating surface. ### Case 404 on a dynamo with extra communication [unclear] whereby two or more circuits with currents of different tension may be taken off the same [unclear]. ### Case 422, on [unclear] around secondary batteries, [unclear] an other source of electro [unclear] force, so as to get circuits of different tension. ### So there any reason why these patents should not be issued. If not we will pay the fees and get them out." Yours truly, Dyer + Seely
