        I.—TREATMENT OF CAMEL SURRA.

IN November last I went to Montgomery and chose
twelve camels from about 40, belonging to the 56th Camel
Corps, which were about to be destroyed, being affected with
surra.

Twelve of the best were selected and marched to
Lahore.

Of these twelve, eight were used for the "orpiment
alone" treatment, one of them being for about three weeks
kept on the atoxyl and orpiment combined treatment.

Three of the eight died within a few days from the effects
of the red orpiment which is too poisonous to be of service
in the treatment of the disease, so results must be judged on
the remaining five cases, treated with yellow orpiment.

In every case, treatment had not the slightest effect on
the course of the disease, even though enormous doses were
given, the total amount of yellow orpiment given to one
camel amounting to 900 grammes.

Camels are extremely sensible to small doses at the com-
mencement of treatment, i.e., before a tolerance has been
acquired for the drug.
