cloth, where are grouped some hundreds of eggs which she has 
laid. The male moth might be pinned to another corner of the 
cloth, but the examination of this creature is unnecessary, as 
he does not convey the disease. The female moth, after having 
been thoroughly dried by free contact with the air, is examined 
at leisure — as during the winter or autumn. Nothing is easier 
than to discover whether there are any pehrine corpuscles in 
its dead body. The moth is crushed in a mortar and mixed with 
a little water ; then a drop of this is examined by means of a 
microscope. If corpuscles be found, the bit of cloth correspond- 
ing to the examined moth is known, and burnt with all the eggs 
it contains. 
As has been mentioned, this protective or preservative mea- 
sure has been found capable of unlimited application, and is 
universally adopted. In the Basses-Alps, in Ardcche, in Gard, 
in the Drome, and in other parts, may be met with everywhere, 
during the cultivation season, establishments where hundreds 
of women and young girls are occupied, with a remarkable 
division of labour and under the strictest supervision of skilful 
overseers, in pounding the moths, in examining them micro- 
scopically, and in sorting and classifying the little cloths upon 
which the eggs are deposited. 
When he had completely fulfilled his mission in 1869, and had 
restored to France what might have been looked upon as a lost 
industry, — through the fatigue and intense application to which 
he had subjected himself, — he was attacked with paralysis of the 
entire left side of the body, which left him prostrate for some 
time, and from which he has not yet entirely recovered. His 
proposed method of combating the silkworm-disease was not 
accepted without serious doubts and opposition, — for throughout 
his career he has had to contend continually with determined 
opponents, who have endeavoured, notwithstanding his lucid 
demonstrations, to ignore or minimise the grand results he has 
achieved. In 1869, while still suffering from the severe effects 
of his unfortunate illness, he, impelled by these doubts and con- 
tradictions, had himself carried to Alais, where he struggled, by 
giving directions from his arm-chair, through a repetition of his 
experiments, and succeeded in once more proving the cer- 
tainty and simplicity of his method. The French Government, 
nevertheless, influenced by his detractors, still hesitated to adopt 
his process of culture ; but the late Emperor interposed, and 
offered Pasteur the Villa Vicentia, near Trieste, belonging to 
the Prince Imperial, as a suitable locality for affording a 
convincing test of the plan, as for ten years the silk-harvest 
at that place had not sufficed to pay the cost of the eggs.
