REARING SILKWORMS. 85 



It was all very well, and we would not detract 

 one iota from the honor justly due to these noble 

 scientists, but we deem it most advisable to ward 

 off disease of all kinds, which can assuredly be 

 done by proper care and judicious management. 

 Again I would reiterate what so often has been 

 said : To avoid all manner of disease. Provide

 the cause and recommend the cure of any fatal 

 disease. 



The most malignant disease referred to above 

 is pebrin. This first appeared in 1840, at Pro- 

 vinza. It continued to spread throughout 

 Europe and Asia for more than twenty years. 

 Upon scientific investigation this disease proved 

 to be a parasite, that lodged in all parts of the 

 worm, even in the blood and alimentary canal. 

 It was also found in the miller, in the wings, the 

 feet, and even in the eyes, and also in the sub-

 ages and stages, and wasted their lives so as to
