FORMALDEHYDE STERILIZER FOR :\IAILING CASES It had been the practice in this Laboratory, as in some others, to discardmailing cases after use for carrying infectious material, viz., tuberculoussputum, etc. This is done to protect the carriers and handlers of these casesin subsequent use against possibility of infection from contaminated for sterilizing mailing cases, especially of paper or pasteboard, havebeen unsatisfactory. Boiling, autoclaving and sterilizing by dry heat are, ofcourse impossible without practically destroying the case, and it has beenthought that formaldehyde gas was not penetrating enough to be Fig. 8. The formaldehj^de sterilizer shoAvn in Fig. 8 consists of a galvanized ironbox 18 X 18 X 36 mounted upon iron legs to raise it a convenient dis-tance from the floor. A quarter inch mesh galvanized iron screen tray isinserted on brackets, which hold it about two inches above the bottom ofthe receptable which is of copper. The lid, hinged at the back, carries anouter structure to which is attached an iron rod threaded and carrying athumb nut at its lower end. This may be clamped tightly under the halfstaples on the face of the box, closing the lid firmly into an inset rim, whichis supplied with an asbestos gasket, thereby, hermetically sealing the recep-tacle. The used mailing cases are cast into the apparatus as the specimensare removed from them. One ounce of formalin is then poured down the sideof the sterilizer held in a slightly slanting position, so that it reaches the NEW LABORATORY APPARATUS 485 copper base under the tv
