manifestations of leprosy to a great extent. 2. That it has no specific influence over the constitutional taint or leprous cachexia. 3. That ordinary Sweet Oil is equally efficacious as far as the local effect is concerned, and therefore it is not improbable that the benefit which patients experience from the application of Gurjun oil is due to the friction producing absorption of the deposits which are effused into the skin and cellular tissue during the course of the disease. Dr. Dougall may have failed in finding in Gurjun oil a specific in leprosy, but he has rendered important service in leading us to a knowledge of the vast benefits to be derived from diligent oleaginous frictions in its treatment; and, as he himself justly remarks, "even temporary improvement is worth striving after in such a disease." 161_a_. +Hemidesmus Root+, or +Country Sarsaparilla+. The root of Hemidesmus Indicus, _R. Brown_.

The specimens of Hemidesmus Root, procurable in most parts of India, which are best adapted for medical use are medium sized, about the size of a quill, having a full, peculiar aromatic odour, and a feebly bitter and agreeable taste. The freshly collected root is preferable to that bought in the bazaars, as that is often inodorous, tasteless, and almost worthless. The virtues of the drug reside mainly in the root-bark, hence if the larger roots are employed you get an undue proportion of the inner woody portion, which is comparatively inert. 163. Hemidesmus proves most useful in _Constitutional Debility_, from whatever cause arising; also in _Chronic Rheumatism_, _Constitutional Syphilis_, _Skin Diseases and Ulcerations, especially those of Syphilitic origin_, _Indigestion_, and _Loss of Appetite_. It is best given in the form of Infusion, prepared by infusing one ounce of the bruised roots in half a pint of boiling water in a covered vessel for an hour, and straining. Of this the dose is from 2 to 3 ounces thrice daily. Its efficacy is much increased by being taken while the Infusion is still warm; the addition of milk and sugar renders it so like ordinary tea that children will take it readily; and this is fortunate, as it is a peculiarly useful tonic for the pale, weakly offspring of Europeans in India; for such it may be substituted for tea at breakfast and supper. Some children prefer it to ordinary tea. 164. +Honey.+ Shahad, Madh (_Hind._), Shahad (_Duk._), Modhu (_Beng._), Tén (_Tam._) Téne (_Tel._), Tén (_Mal._), Jenu (_Can._), Mada (_Mah._), Madh (_Guz._), Páni (_Cing._), Piyá-ye (_Burm._), Ayer madu (_Malay_), Saht, Shahd (_Punj._), Mhách (_Kash._).
