hair from the spot to be punctured; clean the skin carefully with 
warm water and soap; place a drop of 0.8 per cent. salt solution on the 
spot, and, with a knife which has been previously heated, cut through 
the skin; then, with another knife, cut a small artery or vein. Only 
in two diseases are bacteria regularly to be found in the blood of

withstands the action of most reagents, while the spirochcete of 
recurrent fever are readily destroyed by addition of fluids, even by 
distilled water.

Of this glycerin jelly, liquefied by the heat of a water-bath, 
pour one fluid ounce into a four-ounce glass-stoppered bottle, add an 
equal volume of the Farrant’s medium and of glycerin. A little 
gentle agitating in a water-bath will soon insure a complete mixing. 
Into this bottle drop a small lump of camphor. From this stock 
solution pour out a little into a morphine bottle, say one-third or 
one-half full, for a working-bottle. In this keep a twisted No. 16 to
