— One of the most industrious of European entomologists, 
and one whose works have excited a decided influence on the 
progress of American entomology, died December 30. We refer 
to M. Achille Guenée, whose general works on Lepidoptera con- 
tained descriptions of numerous North American Noctuide, 
Phalenide and Pyralide. In 1872 we visited the veteran ento- 
mologist at his residence in Chateaudun. During the Franco- 
Prussian war he took refuge in Geneva, where he worked at his 
favorite science. His works are thorough, reliable and com- 
prehensive, and have been of incalculable value to American 
students. He was a lawyer by profession, was an officer of the 
French Academy, and received honors from various scientific 
societies, 
— Zeitschrift fur Instrumentenkunde, Organ fiir Mittheilungen 
aus dem gesammten Gebiete der wissenschaftlichen Technik is a 
new journal, devoted to a new subject, that of instruments used in 
physical and biological science. The list of editors is headed by 
Prof. E. Abbe of Jena, and undoubtedly represents a strong 
editorial corps; the vedacteur or immediate editor is Dr. Georg 
Schwirkus. The journal occupies a new and important field, and 
will be of value to microscopists, as it contains a number of ar- 
ticles on microscopical and accessory instruments. It is of large 
octavo size, published at Berlin, by Julius Springer, the agents in 
this country being B. Westermann & Co. Price $4.50 a year by 
mail from Berlin. 
— A full grown chicken was brought to the market of Shelby- 
ville, Tenn., which was found to possess three legs. A post mor- 
tem examination, made by Dr. Fite, revealed the fact that the 
internal economy was even more queer than the extra leg. The 
craw, heart and lungs were natural, but the intestine, about mid- 
way of its length, subdivided into four distinct canals; these finally 
became reunited into one, and this, just before emerging from the 
*body, divided into two distinct vents. The chicken was found 
also to have two distinct livers one on each side. The monstros- 
ity is a fat and healthy looking’ subject. 
— M. Humblot has lately sent to the Paris Museum of Natural 
History a fine collection of the mammalia and birds of Madagas- 
car. They afford interesting illustrations of the modifications of 
which species are capable. M. Humblot has also sent home 
some live animals, whose habits are scarcely known. Among . 
these are two Aye-Ayes (a mammal very singular in its organi- 
zation, and of extreme rarity). Two species of Hapalemur were also 
Sent (alive). They differ more from the makis than was previous- 
ly believed. . : 
— The Vienna Academy of Science proposes as the subject for 
the Baumgartner prize of 1000 florins, the microscopic investiga- 
tion of the wood of living and fossil plants, in order to ascertain:
