EXAMINATION OF PASTEUR’S DOCTRINES — 103 
—Up to December 31 no change had taken place in 
this infusion. 
(e) Undzluted hay infuston—The infusion was 
slightly turbid on the 17th; on the 20th the 
turbidity was more marked, and before the flask was 
opened, the water-hammer sound and other evidence 
showed that it was entire. The liquid was found to 
be full of minute but very active Bacteria, and con-

Leptothrix filaments. 
(f) The same.—This infusion was examined on 
the same day. It had become turbid at about the

extent. It was distinctly acid. A drop of this 
fluid contained few Bacteria as compared with e. 
(7) Deluted hay tnfuscon.—-On the 20th it was 
discovered that the retort was accidentally cracked. 
The liquid was swarming with Bacteria, and 
possessed an offensive smell. On account of the 
crack, Dr Bastian regarded the experiment as

(2) Diluted turnip infuscon.— This liquid remained 
unchanged. 
Second SER1ES—(Dec. 2oth.) 
The purpose of this series was to ascertain 
whether the irregularities of the results with the 
turnip infusions in the first series, as compared with 
Dr Bastian’s already recorded results, were due to 
the fact that the material used consisted partly of 
rind. Dr Bastian thought that this might be the
