" This is the only instance of the creature being 

 carried away in its shell, and exhibited as a curiosity. 



"The shell of the pearly nautilus is as curious as 

 it is beautiful. 



" It has a number of chambers in it, one after the 

 other. 



"The last formed is the largest; and here the 

 creature lives, the empty rooms being behind it. 



" At first there was but one room ; the creature 

 lived in it. But that wonderful membrane of its 

 went on secreting shelly matter, until it had formed 

 another. 



"When all the chambers were finished, and as it 

 were shut up, the nautilus had attained to its full

FN every fraternity, I presume, there, after a

 which are perfectly understandable to the initiated, 

 and to them mean a great deal, although they may 

 appear very meaningless to outsiders. 



I have found that microscopists, as a general 

 thing, are more addicted to the use of this kind of 

 technical slang than, perhaps, any other class of 

 persons with whom it has been my fortune to asso-

 crept to it through the rest. 



"A fleshy tube unites all these chambers to- 

 gether, from one end of the shell to the other. 

 This tube ends in the body of the animal, and 

 increases with its growth. 



" Ages and ages ago, when the lily stars were in 

 their beauty, a kind of nautilus that is now extinct 

 lived in the sea. 



" The remains of the shells are found in a fossil 

 state, and are called ammonites."

ciate. Among us, at the American Microscopical 

 Society, is to be found a plentiful supply of this 

 article, but we have one pet term which possesses, 

 for us at least, a deal of meaning. Thus, when 

 anyone makes known any particular method or con- 

 trivance, way or manner of manipulating, or piece 

 of apparatus, it is a " Dodge." And, furthermore, 

 to be a true dodge, it must originate with an ama- 

 teur; manufacturers and dealers only originate 

 "pieces of apparatus." But this special term 

 dodge is more particularly and specially reserved 

 for, and used to designate, little labour- or time- 

 saving machines of home manufacture. 



Now. as I desire to do all that lies in my power 

 to help on my fellow microscopists, it is my inten- 

 tion in this communication to bring to their notice 

 some dodges which have originated in our society, 

 with the hope that they may prove as acceptable 

 to others as they have been useful to me. And I
