The voltage of a battery dependa on the number of cells used and not on their size. The voltage of a cell is quite independent of its size. A large coll, such as is often used in a bell ringing circuit, gives not more voltage than a tiny cell used to light a flash lamp,
The size of a cell determines its capacity. A large cell will give more current for a longer period of time than a small cell. Cells of small size soon become discharg- ed when they are used to supply a heavy current.

Marine radio in the Philippines has not as yet reached the stage of development that it has in Ameri can and European countries. Aside from messages sent to and received from American and foreign trans- oceanic ships, marine traffic within Philippine waters is only beginning to acquire life. Con- sidering the geographical construc- tion of these Islands, however, it is believed that marine radio has a bright future in this country. The | Filipino' public is not yet a largo nser of radio when travelling. But publicity given to the service will eventually build up a very substan- tial trade., This is especially ao in view of recent legislation passed by the Philippine Legislature requir ing all inter-island vesuela of 200
