culi, Spirochaeta plicatilis) may often add considerably to its bulk, and may, perhaps, modify its characters under certain conditions. The slime which exists around and between the teeth is composed of the same constituents as the fur on the tongue; all the organisms which are found in the one are found also in the other. Bacillus subtilis exists, however, in greater quantity in this tooth-slime than in the fur, and the rods and filaments are usually much longer in the toothslime, probably because they are not subjected to so much disturbance. In conclusion I have to thank Dr. Burdon Sanderson and Dr. Lauder Brunton, for valuable suggestions, and for the kindly interest they have shown in this work.

BRAXTON HICKS, M.D., F.R.S. Received March 26, 1879. During the ordinary inspiratory effort, the descent of the diaphragm, most noticeable in the male, necessarily produces pressure on the abdominal viscera in contact with its lower surface; these in their turn press down the intestines, which, acting as fluid enclosed in closed elastic sacs, press equally in all directions. Thus during each descent the abdominal walls are projected forwards, as may be readily seen by adapting an instrument similar to a cardiograph resting on three feet, Tracings of the Abdominal Respiratory Wave in the Male. Showing also the disturbance caused by the elevation of the arm and leg, the person being in the supine position. Tracings of the Abdominal Respiratory Waves, from a Female. The first three lines show head and thorax movements, such as turning to look to the side, &c. The fourth line shows the effects of moving the arm and leg. The last line shows the effect of laughing and giggling. The third line gives the ordinary wave the most free from interruption. |
