was found to be excellent in both districts, affording striking and gratifying results
in staying the progress of the epidemic in Manipur and the Nága Hills, and also at
least in stamping it out for the time by its protective power. I am sorry to say, however,
that just lately another epidemic has occurred at Manipur, which is being combated by
renewed vaccinations of the unprotected in that State.

The expenditure is carefully supervised by Dr. Campbell, whose management
has been in every way a great success in the past year, even more so than in the
previous year, considering the great increase in the number of tubes sent out, the
quality and success of the lymph, and the proportional moderate outlay incurred.

The further report on lanoline as a preservative of the quality of this lymph
cannot be furnished until October at soonest, owing to the great amount of work in the
past season, the success of glycerine lymph, and also to fresh lanoline having been
only lately received from England. Dr. Campbell has, however, already commenced
his experiments with it, and his report shall be submitted as soon as possible. Up to the
present, glycerine has proved most satisfactory in this respect, and this glycerine lymph
leaves nothing to be desired, so great has been its success generally, at least 90 per cent.

Dr. Campbell brings prominently to notice the good services of second-grade Hospital
Assistant Pratab Chandra Bose, in subordinate charge of the depôt. I cannot speak
too highly of Dr Campbell's own services, which have been of the highest value and
deserving the commendation of the Chief Commissioner.

                                                                                I have the honour to be,

                                                                                            SIR,

                                                                            Your most obedient Servant,

                                                        CHARLES P. COSTELLO, Surgeon-Colonel,
