Excerpt from The Electric Lamp Industry
While electric lamp manufacture is essentially a scientific industry, the short account in the following pages is not intended as a technical treatise.
Certain data has necessarily been introduced to make the description more complete, which leaves parts of the text open to criticism by those engaged in lamp manufacture.
In the preface to most books one usually makes a formal acknowledgment of assistance, but in the present case it is doubtful if the work would have been compiled if the writer's colleagues had not offered such generous help.
During a period of severe illness and also while in America the author found the value of many friends, and desires to express publicly his appreciation of help from Dr. W. Phillips, who vigorously but kindly "blue pencilled" the original copy in the interests of future readers; also to Mr. Paul Freedman for his help in connection with the material in the chapter on vapour lamps and to Mr. S. B. Staines for his efforts in collecting the illustrations.
To this must be added the acknowledgment of assistance from many friends at the Edison Swan plant; to the management of the several companies referred to in the text, who have given both information and illustrations freely, and to the journals of the various technical societies in England and America.
