Not illustrated. 1908 edition. Excerpt: ...55 of his patients out of 85 did not react, Stadelmann17 and Wolff-Eisner1' 96 out of 192, similarly Junker, Moro, Emmerich, and others. Nevertheless, Pirquet's test is positive in a very large number of people who appear to be free from tubercle, and reveals, therefore, to a certain extent at least, latent tuberculosis. It will be seen from the accompanying tables that in suspected cases the percentage of positive reactions is about the same as with Koch's method. All things considered, Pirquet's test may be considered almost as accurate a diagnostic method as that of Koch, with the added advantage that it does not give rise to any constitutional disturbance. It causes only a slight itchiness at the site of inoculation. Calmette's Method. Shortly after Pirquet had published his first observations, his method was discussed at a meeting of the Berlin Medical Society (15th May, 1907) and here Wolff-Eisner mentioned incidentally that he had observed a reaction when tuberculin was instilled into the eye. Calmettc-1 thereupon carried out a series of systematic observations on the subject, and published his results in the following month (19th June, 1907). 1 le showed that the reaction, now generally known as "Calmette's ophthalmoreaction," is typical and specific.
