says that he has had quite satisfactory results with Meissuer’s and 
Grandry’s corpuscles. The objects fixed by the foregoing solution 
should be well soaked in water and after hardened in absolute 
alcohol. 
The author also gives the following procedure for treating con- 
nective tissue formations with gold chloride. The objects are placed 
for two, three or more hours in a one per cent. chloride solution, acidu- 
lated with hydrochloric acid (100: 1). After having been washed, 
they are placed in the dark in a 1-50 to 1-100 per cent. solution of 
chromic acid for reduction. Though reduction may not at this 
stage be perfect, it is completed later on in oil of cloves, and the 
preparation is then mounted in balsam. The more carefully the 
chromic acid is washed out, the clearer the picture is. The non- 
medullated nerve-fibers and their ramifications are stained almost 
black. The connective tissue cells appear just as distinctly, while — 
the intercellular substance of the connective tissue is unstained. 
Muscle-fibers, striped and unstriped, are stained a greenish-blue 
color. The author states that this method is almost always certain.

Aw Improvep Form or Wricur’s Cotitectinc Borrie.*—Dr. H. 
N. Lyon, of Chicago, having been much annoyed by the clogging of 
the strainer of Wright’s bottle, devised one which obviates this. 
This is an ordinary metal-top fruit jar, in the cover of which two 
holes are made. Into one hole a tunnel for 
the entrance of water is soldered; into the 
other is a tube, about half an inch in diame- 
Ali ter. This tube reaches half way to the bot- 
in) tom of the bottle on the inside, and extends 
Cc 
| far enough above the cover for a piece of rub- 
ber tubing to be firmly fastened to it. Sur- 
. rounding the tube is a square frame, made of 
——— 
four brass rods, reaching almost to the bottom 
of the bottle. This is covered for 4 of an inch 
at the upper end by a brass ferrule, soldered 
i| } to the rods and to the cover. The strainer, 
which is of fine muslin, is made like a long, 
Stnit)«Ss narrow bag, and is drawn over the frame and 
secured by a thread passed around the ferrule. A rubber tube is 
attached to the outer end of the central brass tube, and a spiral
