In the present report, the author gives the result of his attempt to solve the questions whether the labrinthine fluid contains agglutinin or not, and further whether the transfusion of the agglutiniu of the blood serum into the labyrinthine fluid occurs in an immunised animal. Using as the test animals normal rabbit or rabbits immunised with the typhoid bacillus or the choleravivrio, he obtained the under-mentioned results:
1) Though the typhoid bacillus or the choleravivrio is often agglutinated in the serum of the normal rabbit, no agglutination was found in the labyrinthine fluid of the normal rabbit.
2) No agglutination occured with the typhoid bacillus or the choleravivrio either in the cerebrospinal fluid or in the aqueous humour of the eye of the normal rabbit.
3) The proportion of agglutinin transfered into the labyrinthine fluid of a rabbit immunised with the typhoid bacillus, was as 1: 100-1: 200 compared with that in the serum.
4) The quantity of agglutinin in the cerebrospinal fluid and in the aqueous humour of the eye of a rabbit immunised with the typhoid bacillus, was almost the same as that in the labyrinthine fluid.
5) The proportion of agglutinin transfered into the labyrinthine fluid of a rabbit immunised with the choleravivrio, was as 1: 200-1: 400 compared with that in the serum.
6) The quantity of agglutinin in the cerebrospinal fluid and in the aqueous humour of the eye of a rabbit immunised with the choleravivrio, was almost the same as that in the labyrinthine fluid.
7) When the value of agglutinin in the serum is low, it does not pass into the labyrinthine fluid, the cerebrospinal fluid or the aqueous humour of the eye of the rabbit.
8) It may be assumed that the transfusion of the agglutinin of the blood serum into the labyrinthine fluid, has great significance in connection with the physiology of the labyrinth.
