Uses of Testicular Juice.

Brown-Sequard believed that certain organs supply to the body a natural ferment which is essential to health. When this ferment is absent the vital forces degenerate. Under the use of this fluid the functions of organic life are performed with new vigor. Favorable reports of its use in many hundreds of patients suffering from organic nervous diseases are on record.

Extracts of many other organs, especially bone marrow and thymus, have been employed in medicine, but there is so little evidence that they are of any use that they need not be referred to here.
