MONTHLY MEDICAL REPORT. 



COLD and dry winds from the East and North East, have prevailed almost uninterruptedly 

 since the date of the last report. The Thermometer has never i'allen very low, but, in 

 the reporter's remembrance, there has seldom been felt so long a period of piercing cold. 

 This intensity in sensation, is unquestionably attributable to the permanence of the wind 

 in one particular quarter, rendering it nearly certain that that which we have lately 

 experienced, had its origin in some of the great mountainous chains of the continent,- 

 The effect of this peculiar condition of the atmosphere has been very apparent upon the 

 human body. Those complaints have prevailed which have their source in a constricted 

 state of tie capillary vessels of the skin', while others, which require the permanent- 

 application of moisture and cold for development, have been comparatively rare. 



Severe colds, as they are popularly called, have been very general. By this term the phy- 

 sician understands inflammatory affections of the raucous lining of the nose, throat, larynx, 

 and windpipe, characterized by swelling of the membrane, diminution in its secretion, and 

 general fever. Hoarseness, dryness of the throat, long continued fits of coughing, witb 

 scanty and difficult expectoration, have been the predominant symptoms, and) their 

 severity and obstinacy, have given to them, in many instances, an unwonted degree of 

 importance. The disease next in frequency, has been diarrhoea, and there can be no doubt 

 but that the same principle which explains the occurrence of the preceding ailments at 

 this season, is. equally applicable to the pathology of this A mucous membrane is in botli 

 cases the structure primarily, and probably alone affected ; and very trifling circumstances, 

 such as the clothing of the individual, his habits of life, his mode of diet, or some pre- 

 existing weakness, determine the particular form which the disease in that individual 

 assumes. In general, the dirrhceas of the last month have not been characterized by 

 unusual severity, but in two or three instances the reporter has met with a most profuse 

 discharge of blood, unattended, however, by those other symptoms which constitute true 

 dysentery. The third and only other well marked effect of cold which the reporter has- 

 observed, is rheumatism of the subacute kind, affecting the fibrous and muscular structure. 6 , 

 very nugatory, not of an aggravated character, and certainly not deserving the name of 

 an inflammatory affection. He has principally noticed it as affecting the shoulders, neck, 

 and thoracic parietes. 



These are the complaints under which the adult population of London, appear of late 

 principally to have suffered. Among children, hooping-cough arid scarlet fe*er have also 

 been prevalent, and many instances have come to the writer's knowledge, in which these 

 disorders have proved fatal. Small-pox very seldom occurs extensively, and never with 

 any portion oi' malignity in such a state of atmosphere as has lately been experienced. It 

 is, therefore, in strict accordance with this generally received principle, that the wards 

 of the Small-Pox Hospital have been nearly deserted during the last month. 



The remedies which have been most in request within this period, are such as diffuse the 

 circulation, and excite to action and increased energy, the torpid and constricted vessels of the 

 surface. Of these the most decidedly efficacious is ipecacuanha, both in large dud small 

 doses, in large doses to excite vomiting and restore the equilibrium of circulation, in 

 small doses, united either witb white opium, or with calomel, according to the nature 

 of the case, to act as an aperient, or expectorant. A more valuable remedy than this, or 

 one applicable to a greater variety of cases, is not probably to be found on the shelf of- 

 toe apothecary. While others are lauding the virtues of blue pills, and insisting on the
