Total - 25
Dr. Klein reported upon them as under:—
"February 2nd, 1906.
"I beg herewith to report on the examination of the milk samples
"submitted for analysis. As will be seen from the tabular statement,
"two of the samples, namely, No. 7 and No. 23, caused real Tubercle
"with B. tuberculosis ; this would amount to about eight per cent.
"As you will see from the results stated in the tables, a considerable
"number of the animals died spontaneously, but are marked as having
"given negative results in the post-mortem examination, meaning
"thereby that the cause of death was not ascertained. Excepted are
"two such animals, that is animals dead spontaneously; namely, subcu"taneous
guinea-pig No. 12, in which the cause of death was probably
"infection with Proteus vulgaris, and guinea-pig peritoneal No. 23, in
"which the cause of death was Septicæmia due to a virulent B. Coli.
"It will also be seen from the tables that the following samples caused
"no abnormal condition in the animals ; they are:—
"Samples, Nos. 2, 4, 5, 9, 11, 14, 19, 20, 21, 22, 24 and 25, or about
"48 per cent.
