    in order to facilitate cleaning. Here is made nutrient broth of various kinds on a large scale, to be used in the preparation of the various cultures and toxins for use in the stables. This laboratory is also used for the initial work upon crude animal material before it is sent to the chemical laboratory for further elaboration. Between this room and the boiler-house are two compartments, one for stores, the other to accommodate the large high-pressure steriliser which can deal with bottles, containers, etc., of large size. The serum, after being obtained in the collection-labora- tory adjacent to the stables, is taken to a special building recently erected, where all further processes involved in separating it and measuring it into phials are now carried out. The building contains a cleaning-room for all apparatus used in the manipulations ; a sterilising-room, for the heat- sterilisation of the same ; and a phial-room, where the phials, in which the sera and vaccines are issued, are cleaned and prepared for sterilisation, and subjected to scrutiny after filling. The rest of this building is completely closed from the outside air, and ventilated by an ample current supplied by a large motor fan, placed outside in a special building. The air is passed through a germ-proof filter before it enters the main building ; the rooms are constructed with- out angles or corners, and can' be sterilised nightly with formaldehyde vapour, which the sterile, fan-driven air removes again in a few minutes. This sterile section includes:— (1) A store-room in which the sera and vaccines are kept, ready to be run into the issuing-phials. (2) Duplicate rooms in which the process of separating the serum from the clot is carried out. One of these rooms is always being sterilised while the other is in use. These rooms open out of the serum store, and can only be approached through it. A small chamber, in which the serum is mechanically driven through germ-proof filters into the storage bottles, also opens out of the store- room.
