D. PREPARATION OF VACCINE LYMPH.

Owing to the large stock of lymph on hand no preparation was undertaken during the year. It is proposed to allow the present stocks to be reduced considerably before further replenishment. Such action is possible owing to improved methods of production which render more rapid replacement possible when necessary and thus the carrying of large reserves is avoided.

Space has been allotted to us in the new cold storage room at the Central Medical Stores for our stocks of vaccine lymph and other biological products. It is a great improvement and convenience in every way. We moved our stocks thither during the latter part of the year.
