Dr. Lena is an enthusiastic speaker -- possessing an earnest style and direct delivery which enables her to go at once to the very hearts of her hearers. Her lectures and demonstrations are very popular -- interesting alike to men and women. She gives but two lectures to women only -- to all her other lectures men are invited. Some of her demonstrations are very unique -- truly remarkable. Her lectures are highly scientific, at the same time most simply and plainly expressed in common, everyday language.
