research. The most celebrated of the London Physicians 

 has written a work endeavoring to arrive at conclusions re- 

 garding the identity or non-identity of Typhus and Typh- 

 oid fever. For a scientific man there is a similar field for 

 research open in a consideration of the identity or non- 

 id entity of the causes which induce Leaf Disease and Rot. 

 Typhus taken generically would be classed as a malady at- 

 tacking persons rendered predisposed by causes, which had 

 reduced, or impaired, the vital energy of the system ; such 

 as impure air, contaminated water, bad living and long ex- 

 posure to alternations of heat and cold of any extraordinary 

 character. The system of such persons is not sufficiently 

 vigorous to withstand, or may even favor, the insidious at- 

 tack, which comes on, to a certain extent, involved in mys- 

 tery. There is not the slightest doubt that this type of 

 maladies really belongs to the Fungoid class and as the spore 

 is in the blood its elimination is a tedious process, Cholera 

 and many other diseases are gradually being asknowledg- 

 ed to belong to the same class and contagion is supposed 

 to be effected by the fungoid spores being carried about 

 in the air or in the water The great aim of science in 

 dealing with fungoid, or parasitic disease, whether as affec- 

 ting the human or vegetable creation must be first on the 

 principle of prevention being better than cure, and secondly 

 when the disease has really arrived to endeavor to localize, 

 and circumvent it, and to neutralize, and render harmless, 

 the minute particles, which constitute the agency by which 

 contagion is effected. Research tells us that the animal, 

 vegetable, and mineral creations, are bound together by a 

 system of reciprocal obligation so that one cannot get on 

 without the other. The one has to depend on the other 

 to form that state of complete harmony which charac* 

 terizes the workings of Nature. The death and decompo- 

 sition of one race, or genus, of plants form the food for 

 subsequent reproductions. This applies to the vegetable
