they prey on the eggs laid by other insects, — some ‘of 
them in the live bodies and still others minute denizens of 
London trees. The researches conducted’ by Mr. Enoch 
have brought to light some hitherto unknown genera,’ and 
one of the latest was discovered at Holloway.’ ‘Mr: Enoch 
prpares, mounts, sketches and photographs'the specimens 
for which he hunts by night and day in London and, the 
suburbs, and’ the exhibition which he arranged was of 
much interest. 
Microbes in Ink.—Those who have much work with 
the pen sometimes puncture the skin by accident. Occa- 
sionally the wound becomes painful the catise being attri- 
buted to the presence of pathogenic microbes. \' Dr.’ Marp- 
mann, of Leipzig, has recently published the results of the 
microscopical examination of 67 samples of ink used in 
schools. Most of these inks were made of gall-nuts, and 
contained saprophytes, bacteria and micrococci. Nigro- 
sin ink, taken from a freshly opened bottle, was.found. to 
contain both saprophytes and bacteria. Red.and blue 
inks also yielded numerous bacteria. In two instances 
Dr. Marpmann succeeded in cultivating from -the nigro- 
sin ink a bacillus which proved fatal to mice within. four 
days. This ink had stood in, an open. bottle for three 
months, and the inference drawn from the inquiry is. that 
ink used in schools should, be kept covered when not. in 
use.
