Machine for the Preparation of Animal Lymph, as manufactured by us to the order of 

 the Government Lymph Laboratories, etc. 



This machine has been devised for the thorough mixing of the animal lymph with the necessary glycerine. 

 The lymph is poured into the conical-shaped funnel and is carried by means of the revolving spindle through the 

 cylinder. The spindle is of pure nickel screwed with a thread, gradually tapering from a rough thread at top 

 to a very fine thread at bottom. The inside of the cylinder is also of pure nickel. The mixing spindle is run on 

 a compound ball bearing, and is so arranged that it can easily be removed for sterilising and replaced without 

 any difficulty. In order that the bore of the cylinder can be easily cleaned and examined, the cylinder is cut 

 into two halves, and held together when in use by the clamps shown. The machine is mounted on a strong 

 table with marble top, and the working part is encased under a glass cover with hinged door. This cover need 

 not be removed when the machine is at work. By means of this machine the lymph is thoroughly mixed in 

 about fifteen minutes, without any loss of the lymph, which is kept perfectly free from dust.
