REPORT OF THE KING INSTITUTE, GUINDY                                                  9

                                                                  TABLE IV.

Statement showing the number of cases for which vaccine was despatched to different bodies and their
                               cost—-private bodies being excluded—during the year 1918-19.

N.B.—In calculating the cost per case of vaccine, Rs. 475-9-0 has been deducted from Rs. 55,889-15-3 as the
former represents registration fees which are chargred to the bodies concerned.

6. Tables IT, III and IV show the expenditure incurred by the section
during the year. There has been an increase of Rs. 12,571 or 29 per cent in the
net charges incurred. This has resulted in raising the price of vaccine from
4.041766 to 5.189423 pies per case. This rise is chiefly due to the payment during
the year of over three years' arrears of salary to the acting Assistant Director. The
prevailing high prices have also played their part and have caused increases under
the headings of purchase of apparatus, cost of calves, house rent and pay of
menials.

The amount realized under the sale of calves and cost of vaccine supplied to
private bodies during the year shows a slight increase.

                                                        TABLE V.

Returns recorded in the King Institute of Preventive Medicine, Guindy, from the whole of the Madras
                       Presidency according to the month of the year.

7. Table V shows the monthwar success rate reported for the whole of the
Madras Presidency excluding Madras City. The percentage of successful vacci-
nations has fallen to 76.6 per cent, a proportion which is less by 6.43 than that
obtained in the previous year. This constitutes the lowest rate recorded since the
Institute has been connected with the preparation of vaccine lymph. A set back
of this nature, after the introduction of a new scheme from which better results
were anticipated, is regrettable and requires careful investigation to see if any
cause can be found for the apparent want of success. Three important factors
will be considered from this point of view—(1) adverse climatic conditions, (2) the
