Not only was the New York Government a weak one and insufficiently provided with police, but the destruction of the City Hall and Post-Offide and other central ganglia had hopelessly disorganised the co-operation of part with part. The street cars and railways had ceased; the telephone service was out of gear and only worked intermittently.
As far as I can judge from the dissection of the specimen preserved in alcohol, whose viscera were affected by being kept too long in that liquid, the nervous system consists of eleven ganglia, not counting the oesophageal collar; and the digestive apparatus does not differ perceptibly from that of an adult Oil-beetle.
On the other hand, the actions of the paralysers argue a precise search for the ganglia, at all events for the first thoracic ganglion, the most important of all. The Hairy Ammophila, among others, affords us an excellent example of this method.
In the cephalic ganglia of insects are stored up the relics of impressions that have been made upon the common peripheral nerves, and in them are kept those which are brought in by the organs of special sense the visual, olfactive, auditory. The interaction of these raises insects above mere mechanical automata, in which the reaction instantly follows the impression.
It may cause no symptoms or it may interfere with the use of the hand, especially in grasping movements and when the hand is dorsiflexed. In girls it may give rise to pain which shoots up the arm. Ganglia are also met with on the dorsum of the metacarpus and on the palmar aspect of the wrist. [Illustration: FIG.
The intersection of Broadway, Fifth Avenue and 23rd Street, at Madison Square, is the nearest approach to these bewildering ganglia of traffic. It must be owned, too, that the Bowery, with its two "elevated" tracks and four lines of trolley-cars, is a place where one cannot safely let one's wits go wool-gathering, especially on a rainy evening when the roadway is under repair.
If a pencil were placed over the ear, what portions of the brain would be above it and what below? Describe briefly the cerebrum, the cerebellum, the midbrain, the pons, and the bulb. Locate and describe the cortex. State purpose of the convolutions. State the general differences between the cranial and the spinal nerves. Locate and give the number of the dorsal-root ganglia.
But it may, and often does, happen that the catamenia are normally performed, and that the reproductive system is fairly made up during the educational period. Then force is withdrawn from the brain and nerves and ganglia. These are dwarfed or checked or arrested in their development.
Once that is gone, you'll have ripped the heart out of the beast, smashed the vital ganglia, and given the world the respite, the breathing-space it must have, to free itself!" "And if I don't?" asked Gabriel. "If anything happens to upset our blockading tactics, or if our attacking forces are defeated or our aeroplanes shot down, what then?"
The first bite is aimed at the point containing the cervical ganglia and produces sudden death or immobility. Complete inertia will leave the consumer in peace, the essential condition of every satisfactory repast. The Devilkin, therefore, frail though she be, possesses the secret of immediately destroying the resistance of her prey.
