when do they emerge from their host, and do they interfere with 
its vital functions before the eggs are deposited? The beetle was 
one of a large colony of lively specimens captured beneath the 
ruined walls of an Arab hovel at Ismailia on the Suez canal. The 
specimens have been sent to the editors of the AMERICAN NATU- 
RALIST.— SAMUEL H. SCUDDER. 
[It is well known in Europe that several species of Conops, a 
wasp-like dipterous fly, live in the larva state in the abdomens of 
adult humble bees. We have reared a species also from the ab- 
domen either of Bombus vagans or B. fervidus.— Eps. ] 
Mapness 1N A Horse. — In the * Zeitschrift fir Parasitenkunde” 
published in Berlin, a remarkable instance is recorded of madness 
in a horse, caused presumably by the bite of a mad dog. The 
horse was brought to the hospital of the Royal Veterinary School 
at Berlin, having refused its food for two days, and exhibited ex- 
traordinary wildness and propensity to bite, not only other horses 
and inanimate objects, but also its own body, and had already by 
this means broken several of its teeth, and inflicted severe inju- 
ries on its mouth. When confined in a stall in the hospital, it 
cqntinued to exhibit this propensity to a terrible extent, but in a 
fitful manner; in the intervals of the paroxysms it stood in a be- 
wildered state, and would sometimes suddenly fall as if struck by 
lightning, then give a violent bite to one of its hind feet, then as 
suddenly spring up, staggering. The loss of blood caused it to 
become gradually weaker, and in the evening of the day on which 
it was admitted, it expired without any death-struggle. Except 
the outward injuries, and some interior swelling and inflamma- 
tion, the organs were found to be sound after death.—A. W. B. 
ANTHROPOLOGY. 
WHERE ARE THE Bones or Prenistoric Men?—In answer to 
this inquiry, M. W. Pengelly states in the ‘‘ Quarterly Journal of 
Science” that their bones may be more subject to decay than the 
bones of other animals, citing the experiments of Dr. Lindley who 
‘t placed in water, in a tank, one hundred and seventy-seven spec- 
imens of various plants belonging to all the more remarkable 
natural orders, including representatives of all those which are 
constantly present in the coal measures, and also those which are
