SUMMARY OF CURRENT RESEARCHES RELATING TO 
net D (fig. 114), constantly stirring during aspiration, or by placing it in 
a beaker C (fig. 115) with the bougie-filter inside. 
For securing the legs of rabbits the author substitutes for the ordi- 
nary fastening a more secure contrivance (fig. 116). To the obliquely- 
cut side of the board A is fixed an iron rod B, on which runs the 
fixation clamp. This consists of the piece DCF which is split on the 
rod B — D and fixed by the clamp E. At H is a joint on which moves 
the piece G, the lower fang of the forceps. As G on its anterior half 
is split in two, the space K can be reduced to nothing, as the two prongs 
of G allow F to pass between them. There are four of these grips, one 
for each extremity, and all are covered with rubber. The limb is 
fastened after it has been passed through K by pressing F down and then 
screwing up E. For fastening the head the author uses a modification 
of Tatin’s apparatus, which prevents operations on the brain and 
sometimes on the face, while the apparatus shown in fig. 117 allows of 
both. 
Suggestions on Bacteriological Technique.* — Dr. A. P. Ohlraacher 
uses commercial benzene in the technique of bacteriological autopsies 
on small animals. The benzene is employed as a bath for the instru- 
ments and also to disinfect the surface of the animal’s body before the 
final incision. After the skin has been removed the benzene is applied 
to the surface and then ignited. When the instruments are required they 
are removed from the dish, the benzene is lighted and allowed to burn 
off. The instruments should be redipped and ignited as each particular 
organ is dealt with. This procedure, if properly carried out, satisfies all 
the requirements of antisepsis. 
By far the best methylen-blue is that proposed by Ehrlich for blood- 
work, especially for staining intra vitam (“ methylen-blau nach Ehrlich ”). 
This dye gives much better and more effective results than the pigment 
ordinarily used. 
For staining the diphtheria bacillus methyl-violet 5 B (Griibler) is 
highly recommended. To a saturated alcoholic solution of the dye, 
water in the proportion of 10 to 1 is added.

Use of the Microscope in Fermentation Industries, with an Intro- 
duction to Study and Cultivation of Yeasts.j - — The work of Herr P. 
Lindner is intended for persons engaged in brewing and other fermenta- 
tion industries and appears to be admirably adapted for their require- 
ments. In it are described the Microscope and its manipulation, the 
fittings and apparatus requisite for a fermentation-laboratory, their 
application, the appearances of the different yeasts under cultivation, 
the method of isolating particular organisms, the sources of contamina- 
tion and the effects of deleterious organisms, the determination of the 
number of organisms present in wort, beer, water, &c., and in fact, every 
branch of the subject that is likely to interest the student of fermenta- 
tion and the practical brewer.
