26 BURMA, ITS rEOPLE AXD PRODUCTIOXS. 



in fresh vaccine Ipinph of either man or animals, and also in the matter of true 

 small-pox. If vaccine lymph is strained or iiltered to eliminate the Microcioccm cells 

 or corpuseules, the lymph loses its power of producing cow-pock. The lymph also 

 loses its power by putrefaction, during which process the Micrococcus disappears 

 under the action of the putrefactive Bacteria. This species is a trae animal ferment, 

 and is probably only one of a numerous class of similar organisms which constitute 

 the true origin of various diseases. 



M. DipniHERiiicrs, Cohn. 



This species is developed on wounds, and also on the various mucous surfaces in 

 Diphtheria. Once established, it spreads rapidly by means of the lymphatic vessels, 

 and produces the most destructive and fatal results. 



M. (MicEOSPOEOu) SEPTicus, Klcbs. 



Developes on suppurating -wounds and putrefying surfaces, and is the active 

 agent in producing pijamia and seplicamia in man and animals. 



M. (Miceoztjia) BoMBTca:s, Bechamp. 



This species is developed in the intestines of silk-worms, causing a fatal and 

 contagious plague in those insects. 



Such are some of the enemies by which animals are surrounded and threatened, 

 but there is little doubt that to other similar species of minute vegetable organisms 

 are due the most formidable diseases wldeh threaten man — Leprosy, Consumption, 

 Typhus, and many others. 



Order FUCACE^. (Sea-wracks.) 



" Olive-coloured inarticulate sea-weeds, whose reproductive organs are borne 

 in stalked sacs upon the walls of the spherical cavities excavated in the substance 

 of the frond. Fructification, Sporangia or spore-sacs and Antheridia. The spores of 

 FucHS divide into two, four, or eight within the sac ; those of other genera remain 

 undivided. The Antheridia are filled with spermatozoids (or antherozoids), which 

 in Fuciii have been seen to fertilize the spores." — Griffith and Henfrey. 



" Cellular or tubular unsymmetrical bodies, multiplied by simple spores formed 

 externally." — Lindley.
