It has been shown by microscopicinvestigation that in silkworms strongly affected with this disease,every tissue and organ in the body is swarming with these minutecylindrical corpuscles about 42^u long, and that these even pass intothe undeveloped eggs of the female moth, so that the disease ishereditarily transmitted. And it has been further ascertained bythe researches of Pasteur that these corpuscles are the active agentsin the production of the disease, which is engendered in healthysilkworms by their reception into their bodies; whilst, if due pre-cautions be taken against their transmission, the malady may In-completely
