A manual of diseases of the nose and throat . Transformer for adapting the street current (constant) for both cauteryand transilluminating work. means of which the constant current may be employedboth for cauterization and heating small lamp for ex-amining the air-passages and ear, or transilluminatingthe accessory sinuses of the nose.

The Schechcautery handle (Fig. 22) is the most practical and con-venient one for holding the electrodes. It is consider-ably more expensive, however, than the smaller handleshown in Fig. 23.
