conclude that the disorder was acquired by feeding in the road and ditch bottoms.” The precautions applicable to the sheep and cattle will be deemed equally applicable to the labouring population who traverse such roads. Such instances as the following, on the prejudicial effects of undrained and neglected roads, might be multiplied. _Mr. E. P. Turner_, the medical officer of Foleshill union, in accounting for some cases of fever, states:— “These cases of typhus all occurred in the same neighbourhood, where the road is bad and a dirty ditch of stagnant water on each side of it; the road is generally overflowed in the winter. The disease broke out in the month of October; other cases occurred in the same neighbourhood at the time.” The nature of the more common impediments which stand in the way of the removal of the causes of disease and obstacles to production described in the preceding, are noticed in the instances following. Others will be adduced when the subject of the legislative means of prevention are stated. _Dr. Traves_, on the sanitary condition of the poor in the Malton union, states,— “The whole of the low district above alluded to, and extending into the Pickering union, (known by the name of the Marishes, or Marshes,) has at different times within the last few years been the seat of typhus and other fevers. “Attempts were made by some of the landed proprietors a few years ago to effect a system of drainage and embankments likely to prevent the inundations of these rivers in wet seasons, but the attempt was abandoned in consequence of the reluctance of certain townships to bear their portion of the necessary outlay, and any partial system of embankment is positively injurious, inasmuch as the water that is let in upon the land at a higher point of the river is prevented returning into the stream again by an embankment at a lower point, so that this water, containing vegetable matters in a state of decomposition, must remain stagnant until evaporated by the sun’s rays, or dissipated by the wind; cases of fever occurring under these circumstances have repeatedly come under my observation, as well as that of other medical men familiar with the district, and this fruitful source of disease (in seasons like 1839 more especially) will probably now remain in full force until an Act of the legislature shall effect a change.” _Mr. Thomas Marjoribanks_, the minister of Lochmaben,—
