all or nearly all of the appendages react strongly to chemical stimuli and 

 in many cases the surface of the body is capable of receiving and re- 

 sponding to stimuli of various kinds. In some places the skin of the 

 lobster with its shelly covering seems quite as sensitive as that of the 

 frog. The organs by which the stimuli are conducted through the chit- 

 inous shell must be either the hair pores or the glandular ducts. The 

 author decides in favor of the latter.

Pain ill the Pectoral Region Sympathetically Accompanying Irritation 

 of the Forearm ' 



The patient, a fireman, developed very peculiar symptoms, prob- 

 ably as the result of a fall and injury of the back and elbow. Con- 

 stant though unequal pain is felt in the right shoulder on the right side 

 of the back at the level of the seventh dorsal spine. On the right side 

 of the chest, in front, there is an area bounded laterally by a vertical 

 line from the axilla to the sixth rib and mesially by a line laterad of the 

 right nipple. The pains felt here have a burning or tearing character. 

 Beneath the right nipple is another painful spot which only announces 

 itself after exertion, as rapid walking or turning in bed. The posterior 

 aspect of the right arm also is subject to pains, generally induced by 

 pressure over the radio-humeral articulation. The area does not in- 

 clude the fingers but extends upon the dorson of the hand. Bending 

 the elbow causes severe pain, as does movement of the Avrist, though 

 there is no swelling of the joints. 



A touch on this arm area is felt in the pectoral area, as well as in 

 the arm; firm pressure over any part of the arm area, except the pain 

 centre over the joint, causes severe tearing pain in the pectoral area. For 

 years the patient had been in the habit of sweating profusely with the 

 right side only though when at work all parts perspire alike. A fall a 

 week or so before the symp toms appeared injured the elbow and back 

 and there seems to have been a blow of a less violent sort on the chest. 

 The author thinks this a case of sympathetic neuralgia but there is dif- 

 ficulty in discovering the nervous connections necessary to satisfy the 

 hppothesis. c. l. h.
