The first frost of the season is reported from a large number of stations, and first snow from about twenty.
Verifications.—The average is 92.8 per cent. for the weather; 90.1, wind direction; 91.1, temperature; 87.7, barometric changes. For the whole country the average verified is 90.4 per cent. There were four omissions to predict out of 3,720, or 0.1 percent.
A severe earthquake shock was felt at San Francisco at 9:20 p.m., on the 6th, lasting ten seconds; motion from northwest to southeast. A second and lighter shock was felt the same day.
FRENCH NATIONAL ANTIQUITIES.
Probably few American travellers visit a collection of antiquities, infinitely older than the paintings, statues, and relics of mediæval life, or even than those of Roman and Grecian age, but which is as freely open to them, near Paris. This is the museum which has been established in the château of Saint Germain. France has been particularly fortunate in rescuing fragments of the life which existed within her borders long before the day of the very earliest races to which history points us. These fragments have sometimes been preserved in the most fortuitous manner, and afford unique illustrations of the remarkable accidents to which man is occasionally indebted for his knowledge. The fossil man of Denyse, whatever his age may have been, has been preserved for our inspection by becoming overwhelmed in a volcanic eruption. The skeleton of Mentone was found by Rivière while engaged in a systematic search among French caves. Other caves in France have preserved evidences sufficiently distinct for us to gain valuable hints of ancient life. In fact all the ages of man, so far as they are recognized, and all the kinds of proof concerning them, are well represented in French collections. During the reign of the late Emperor this museum was founded, and has received the case of many noted French savants who have won distinction in this field of research. The walls are covered by finely painted maps illustrating the distribution of caves, and rock shelters, and places where instruments of stone, bone, and bronze have been found. Pictures are also exhibited which illustrate the views of former social customs which are thought to be supported by the material evidences assembled in the château. In the cases are not only large collections of celts, but also the carved bones, horn, and stones which, by their distribution through the stalagmite of caves, or through the gravel of ancient river beds, give infallible proof of the presence of man. One floor contains a collection not less interesting, though illustrating the manners of a much later age. It is formed of the military weapons, bridges, fortifications, camps, etc., which were constructed to illustrate the "life of Cæsar," by Napoleon. This collection is, and will probably remain, unique. At the meeting of the Geographical Congress last year, these great engines of war were taken to the park and exhibited in action. The museum is now placed under the control of the historical commission for constructing the map of Gaul. This body is publishing a series of maps and engravings to illustrate the progress of the science of the prehistoric and subsequent periods. A catalogue of the collections has been made and is sold to visitors. There is also in the establishment a special library in which has been collected by M. Gabriel de Mortillet all the books relating to prehistoric antiquities, and which is open free on certain days to the public.
It is found that insects preserve their colors better under yellow glass than in any other color. The curtains of entomological show-cases and the blinds of the room should be yellow. Only in this way can the delicate carmine tints of some insect wings be preserved.
A student of animal nature announces a case of two hens, who by joint efforts hatched one chick. They have since, for some weeks, been parading the yard, each clucking and manifesting all the anxiety and care of a true mother over this one. The hens never quarrel, or show the least appearance of jealousy or rivalry.
M. Tresca, who has charge of the Conservatoire des Arts et Métiers, the institution which in Paris answers to our Patent Office, says that drawings of new inventions are more useful than models, are cheaper, and are very much oftener consulted. In Paris the model room is covered with dust and rarely entered.
The French weather bureau intends not only to study the thunderstorm, hailstorm, rainfall, inundations, and frosts, with especial reference to their effects upon agriculture, but also to experiment upon the asserted effect of smoke as a preventive to frost. The experiments will be extensive and may cover a large valley.
