could not be distinguished. No 2 best preserved, still no 
chains. In No. 4 are masses of bacteria ; at the edge a 
large mass of zoogloea, has made its appearance, amongst 
which are found a few penicillium threads, so at all events a 
part of the bacteria may be supposed to have come in from 
the outside, but this bacteria* containing zone has not en- 
croached farther into the preparation than before. 
21st. — In Nos. 1 and 2 in many places, in the middle of 
the preparation, masses of zoogloea. 
March 24th, 1873. — Uatel Espeland. Eruption. Punc- 
tured an umbilicated tubercle that had become tender by 
the eruption ; blood and the whitish contents collected. 
Two preparations were made. In both gigantically large 
brown elements to be found ; no bacteria. Water was added 
to the one preparation. As long as this flows quietly in, 
and the glass cover be not moved, no bacteria appear, whilst, 
however, a large portion of the cells swell up; by moving 
the glass cover up and down, and pushing it a little to one 
side, a large portion of the cells break, and now bacteria 
appear in the fluid. 
25th. — Preparation unchanged. 
27th. — In the preparation to which water has been added 
numerous articulated threads are especially remarkable, 
issuing from a brown body ; the connection confirmed by 
the movement of the glass cover. By these means it was 
ascertained that the whole mass in the lower element, to- 
gether with the apparent articulated threads, remained con- 
nected in all positions of the former (fig. 5). 
April 18th. — Ratel Espeland. From a puncture of a 
tubercle on the forehead ; pressed out contents of it ; this, so 
firm that it must be teased out with needles. One prepara- 
tion was made in salt solution, and one in distilled water ; in 
both an immense quantity of bacteria ; the cells large. In 
the preparation with distilled water bacteria are to be seen 
in almost all the swollen-up cells, some wdth rather lively 
movements. The situation of the bacteria within the cells 
ascertained in the most evident manner, by getting the 
cells to roll in the fluid ; no granules for the most part can 
be found in the cells, and where such is the case, they 
oscillate with far greater speed than the slow-moving 
bacteria. 
20th. — Many bacteria can be found in the water prepara- 
tion, which are those with 3 — 4 — 8 articulations. In the 
salt-water preparation the cells are not a little shrivelled ; by 
the addition of water a large portion of them are very 
quickly set free ; a crowd of granules stream out in
