 MICROSCOPICAL APPARATUS. 



A Convenient Sterilizer. — Mr. Adolph Levy, chemist, of 

 145 Grand street, Brooklyn, N. Y., sends to us the following de- 

 scription of his invention : 



The present demand of sterilization of instruments and dress- 

 ings at surgical operations (in private practice at the residence 

 of the patient) and the necessary inconvenience of carrying a 

 heavy or cumbersome apparatus induced the writer to transform 

 an ordinary farina boiler made of extra heavy tin with copper 

 bottom for this use. It is in use with many active surgeons who 

 regard it as an efficient and useful adjunct in conducting major 

 operations, where antiseptic precautions are necessary. 



A Convenient Sterilizer. 



A six-quart farina boiler composed of two parts, the outer to 

 contain the water (about 3 inches in height), bringing it within 

 one inch from the bottom of the inner container, which bottom 

 has been removed and a well-tinned and perforated one replaced. 



The lip on the outer container serves to add boiling water from 

 time to time, after which it is packed with ordinary cotton.
