tween stationary cells. This appears on bread-fruit, glue, saccharine 

 fluids,, is often parasitical, and of a mouse color. The mycelium, 

 conidia and endogonidia were all well brought out and elicited con- 

 siderable interest. The family mucorini was well illustrated from 

 both lemon and orange peel. Quantities of these fruits had been 

 used in making juice for the soda fountain. After the rind had 

 been pressed and strained from moisture it was heaped together in 

 a moist and shaded exposure. Within five days the entire outside, 

 and indeed nearly all the interstices of substrata, were thoroughly 

 covered with the genus Mucor niucedo. 



In remarks by members it was the general opinion that the 

 microscope should be one of the important instruments of the drug- 

 gist of the present and future, for drugs come into the market often 

 so changed in form that with the eye the adulterations cannot be 

 detected. 



The Society adjourned to meet (according to the Constitution)

" CLEANLINESS IS AKIN TO GODLINESS." 



INSTRUMENTS and material required. — 1. A good section-knife. 

 2. A carpenter's glue-pot. 3. A large pipette. 4. One pound 

 of paraffin-mass. 5. One ounce of ammonia-carmine. 6. Two 

 ounces of xylol. 1. The section-knife possesses a rather long blade, 

 flattened on the under surface and provided with a fixed handle. 

 With practice, however, an ordinary razor of best quality will do all 

 that is required. 4. Paraffin-mass is prepared by taking 14 ounces 

 of the hardest and 2 ounces of the softer paraffin and melting to- 

 gether in the glue-pot over a water-bath. Stir constantly that they 

 be thoroughly mixed. This mass will prove to be of about the right 

 consistency. The hardness will vary somewhat with the temperature 

 of the room. If softer mass is desired it can be made by varying
