THE MICROSCOPE. 



BACILLUS. 



BY J. M. ADAMS. 



F the late idea advanced be true — that the bacillus be nothing 



I 



but fat cells modified — then it would not hold good that they 

 exist where no fat exists, particularly where the fat has all been 

 absorbed. 



I once found a spring-poor old bat, so poor that he was about 

 dead and had nothing but a few feathers over his lean flesh and 

 bones, and yet his blood, as well as muscles and lungs, were literally 

 filled with well-formed bacilli. He was really poisoned to death by 

 these numerous bacilli, and not a granule of fat could be supposed 

 to exist anywhere in or about them, and they multiplied all the more, 

 the more diseased the animal became — no fat to absorb, no fat could 

 exist in such a state, and no fat at all. 



A 



CRYSTALS OF SODIUM CHLORIDE. 



BY E. E. JACKSON. 



VERY instructive and simple experiment to exhibit crystals of 

 sodium chloride under a low microscopic power, say |, is to 

 mix Qn a slide a little solution of salt and alcohol. As the alcohol 

 seizes the water the salt crystalizes in clear brilliant cubes, the heat 

 generated by the union of alcohol and water causes evaporation and 

 a steady tumbling over of the perfect cubes. Perhaps this is not 

 new. 



I have frequently used liq. pot. and sol. tart, acid to obtain 

 pretty crystals of cream tartar to amuse friends. Using potassium 

 it is quick and handsome. 



THE BIOPLASSON THEORY OF HEITZMANN— A RE- 

 VIEW OF HEITZMANN'S "MICROSCOPICAL 

 MORPHOLOGY." 



BY C. H. STOWELL. 



SOME three years ago my attention was seriously called to the 

 reticulated structure of tissues. Since that time the subject 

 has received more or less attention, and for a few weeks before my
