Extract irom British Medical Journal. Dr. C. L. Birmingham (Westport, co. Mayo) writes to draw attention 

 to a form of micsoscope slide which he has used for some years, and which he regards as both convenient and time- 

 saving. The device consists in having about half an inch of one extremity of an ordinary slide bent upwards at 

 an angle of 40 degrees. When such a slide is used for smear work it will be found, he says, that (i) the fingers do 

 not get stained, (2) the slide can be dried by simply inverting it, and (3) there is no doubt as to which side contains 

 the film. He adds that it is specially convenient for taking sputum specimens at the bedside, and that they can 

 easily be fixed at once, preferably by " spiritine."
