Immunity of Animals from Syphilitic Inoculation. —Pro¬ 
fessor Neumann lias made a number of attempts to inoculate 
animals with syphilis, but without success. The experiments were 
made with the greatest care, the virus being taken directly from 
the diseased person and introduced into the body of the animal. 
The animals experimented upon were kept under observation for 
a considerable period of time after the inoculation. In no case 
did any results obtain other than those which would naturally fol¬ 
low the introduction of an irritating material into the tissues. Noth 
ing that bore any resemblance to a chancrous tumor was observed. 
The animals employed in these experiments were three apes, three 
rabbits, a horse, a hare, a white rat, a marten and a cat. The to¬ 
tal number of inoculations was fifty-four. Neumann concludes 
from these experiments that we must regard syphilis as distinctly 
a disease of man.— Med. Central-Zeitung, January 24, 1883. 
The Cultivation of Tubercular Bacilli. —It is somewhat 
noteworthy that although a year has passed since Koch announced 
his discovery of the bacilli of tuberculosis, no one has yet repeated 
his experiments. The explanation is, no doubt, due to the fact 
that the experiments are difficult and require a large outlay of 
time and money, besides much technical skill. We learn now, 
however, that Professor Feltz, of Nancy, has been attempting to 
cultivate the bacilli, following strictly Koch’s descriptions. ITe 
announced recently that all these attempts had proved utter fail¬ 
ures, although he exactly followed the directions given him by Dr. 
Koch for this purpose in his original paper. “ In presence of my 
failures,” he says, “ 1 could not be sufficiently thankful if I were 
furnished with the necessary information to enable me to avoid 
this kind of misadventure: for I would not cast a doubt, from 
the facts only which I have just mentioned, upon those which 
Dr. Koch has so positively affirmed.”— Med. Record. 
A n Instantaneous Light. —Such in a word is the unique ap¬ 
paratus on exhibition at the rooms of the Portable Electric Light 
Co., 22 Water Street, Boston. It occupies the space of only five 
square inches and weighs but five pounds, and can be carried with 
ease. The light, or more properly lighter, requires no extra
