Recently much work has been done in order to find a serologic test which will be positive in all cases of syphilis of the nervous system. Collins1estimates that 15 per cent. of paretics and 70 per cent, of cerebrospinal syphilitics fail to give a positive Wassermann reaction in the spinal fluid. While these figures are perhaps higher than the average, the fact still remains that a definite percentage do fail to give a positive Wassermann. Collins1also estimates that 97 per cent. of these cases give a positive colloidal gold reaction. Any one, however, who has prepared the gold solution and has carried out the test cannot but be impressed with the many difficulties it entails. While working with the colloidal gold solution, Emanuel2endeavored to find a substitute which could be more easily prepared and in which the reaction could be carried out with lessKeywords
