M. A. Sabatier (“ Comptes Rendus,” xcii., p. 200) has made 
some interesting observations on the formation of the blastoderm 
in the Araneida. Their eggs present a type intermediate be- 
tween those of the Crustacea ( Peneus ) with a general superfi- 
cial segmentation and such with a regular discoidal segmentation, 
like those of certain fishes. The affinity of the Araneida with 
the other groups of Arachnida and with the inseCls is very 
distinct. 
According to a paper read by M. Pasteur, before the Academy 
of Sciences, the saliva of a child, dead of well-pronounced hy- 
drophobia, when introduced beneath the skin of rabbits, proved 
fatal in thirty-six hours. The symptoms, however, were quite 
distinCt from those of rabies. In every case the blood of the 
deceased animals contained microscopic organisms of the form 
of a short rod, a little constricted about the middle. Each was 
apparently surrounded by an aureola of a mucous substance. 
Guinea-pigs resist the new disease, but dogs perish with symp- 
toms quite distinCt from those of any type of rabies. 
According to Miss S. P. Monks (“American Naturalist”) the 
larvae of the dragonfly ( JEschna ) use their power of ejecting a 
stream of water from the branchial apparatus at the hinder end 
of the body as a means of defence. 
Mr. E. B. Wilson places the Pycnogonida intermediate be- 
tween the Crustacea and the Arachnida. 
In the same journal is an account of some important experi- 
ments on the aCtion of Pyrethrum powder upon cabbage cater- 
pillars, potato-beetles, aphides, mosquitoes, and other noxious 
inseCts. The results were satisfactory except in the case of 
Coreus tristis , a bug which infests vegetable marrows. 
Baron von Reitzenstein (Psyche) describes an aquatic lepi- 
dopterous larva belonging to the family of the Sphingidas (genus 
Philamfelus). It feeds on water-plants and swims well. 
According to the Report of the Mining Registrars of Victoria, 
for the quarter ending September 30, 1880, the total quantity of 
gold obtained has been 222,014 ozs * ^ dwts. The bullion ex- 
ported was 58,080 ozs. 19 dwts., besides specie to the amount of 
£1,117,286. 
Mr. Lester F. Ward contributes to the “American Naturalist” 
a most interesting paper, on “ Incomplete Adaptation as illus- 
trated by the History of Sex in Plants.” He argues that adapta- 
tion is never absolutely complete.
