248 gas used was equivalent to 33 grammes of cyanide to 100 cubic feet of space. Shelves were fixed across the window of the room, and on them the cages containing animals and insects were placed for easy examination. House flies exposed in the ordinary wire traps were killed in from two to four minutes after effervescence began in the cyanide jar. Bed-bugs were placed in tubes plugged with two inches of cotton, and these were put inside a Florence flask plugged with five inches of cotton. The bugs were therefore under The room was closed in this experiseven inches of cotton. ment for 25 minutes, when all were removed at once to the open air and examined. Out of 60 or 70 insects two very young ones were alive. In a Florence flask with the mouth wrapped thickly with cotton mosquitoes (culex pungens) Small black ants in test-tubes were killed in four minutes. with one of inch cotton were killed in five minutes. plugged Rats in cages fell in convulsions in from two minutes to three and a half minutes from the beginning of the evolution of gas and ceased to move in from 30 to 40 seconds after falling. Mice and guinea-pigs succumbed more easily than did rats. Dr. Fulton and Dr. Stokes conclude that in hydrocyanic acid gas an exceedingly rapid and powerful agent is available for the destruction of all animal and insect pests within all fairly tight enclosures, and they point out that by its prompt action on mosquitoes, rats, and flies it is likely to be useful in the prophylaxis of yellow fever, malaria, filariasis, plague, and enteric fever. The gas is, of course, extremely dangerous to man, but they say that it is by no means unmanageable. After each of the experiments the room was entered instantly for the purpose of removing insects and animals, no other precaution being used than the suspension of respiration while in the room.
always the case. We do not know of any recorded case of small-pox attacking a person who not only has previously had the disease but has also been subsequently successfully vaccinated. Many small-pox patients state that they have had a previous attack, but if careful inquiry is made into the symptoms, distribution of eruption, and duration of illness, and if the scars, if such be present, are examined, the alleged first attack usually proves to have been chicken-pox. Dr. J. MacCombie, writing in Professor T. Clifford Allbutt’s "System of Medicine," states that in threefourths of the cases of so-called second attack that have come under his notice he was able to satisfy himself that the first attack had been one of chicken-pox, and in most of the others there was not sufficient evidence to show whether the first attack had been small-pox or not.

OPERATION FOR THE REMOVAL OF PROMINENT ALVEOLAR PROCESS OF THE MAXILLA.
of the anterior portion of the when edentulous, is often a source of much trouble to the dental surgeon who is anxious to insert a satisfactory and artistic denture. In the January issue of the International -Dental Journal Dr. W. Howard records a case where the difficulty was overcome by removing a portion of the prominent bone. An incision was made from the region of the canine on one side to that on the other, the line taken being along the summit of the alveolar process. The muco-periosteum was raised and the bone was exposed for some distance both on the labial and the palatal aspects. The alveolus was then removed with bone-clippers to a depth of from one quarter to half an inch from the canine to the canine. The rough edges of the bone were smoothed and the mucoperiosteum was then replaced and trimmed, a sufficient amount being allowed for shrinkage. The edges of the wound were united with catgut sutures. The result was in all respects satisfactory from an æsthetic point of view. AN
