FACTS AND OBSERVATIONS. 
215 
by Herr Harz was presented to the class on the above sub- 
ject. The author thus classified his results in summarising 
his paper: — 1. This secretion in its first formed condition 
does not possess the common properties of the fat-oils. 2. It 
is inclosed almost till its complete development in true secre- 
tion-cells, the walls of which can be made visible by reagents. 
3. These secretion-cells are not simple, but contain within 
themselves a number of other secretion-cells (daughter-cells), 
which, gradually developing, are finally converted into oil, 
while the membrane of the mother-cells itself also changes 
into oil. 4. This membrane was rendered visible by treat- 
ment with Miller’s salt, or still better, first by this salt, then 
with aniline solution, and lastly with iodised chloride of zinc, 
these three reagents together colouring it a beautiful deep 
blue. — Ibid. 
Influence of the Hop on Fermentation. — If we 
are to believe the statements of Signor Tigri, the flowers of 
the hop arrest immediately the development of yeast. — Ibid. 
The Scarlatina Fungus. — Hallier asserts that scarlet 
fever is the product of a fungus which he names Tilletia scar- 
latinosa. We hope it will be better established than his well- 
known cholera-fungus. He says he has never seen such an 
immense number of micrococci in the blood of any other 
infectious disease. These are at first as small as the finest 
pin-point, or the most minute granular matter. They are 
present in far greater numbers than the blood-globules them- 
selves ; both swimming free in the serum and accumulated 
in granular masses and groups. They both accumulate on 
and penetrate into the blood-globules. The white corpuscles 
as well as the red globules are supplied with them, almost 
without exception. Just as there is a great resemblance 
between the seeds, roots, stems and leaves of plants, so do 
the microscopic germs develop themselves into sprouts and 
shoots which resemble those of many other microscopic 
plants. — Ibid. 
Brunner’s Glands not Follicular. — At a late 
meeting of the Academy of Sciences of Vienna, Herr Briicke 
presented a paper, by Herr A. Schlemmer, on the character 
and position of the intestinal glands known as Brunner’s. 
He finds them most abundant in the horse-shoe bend of the 
duodenum, and he states, further, that they are not follicular 
glands, as has been asserted, but are truly tubular structures.
