2. How much Sodium Chloride per 100,000 parts is there in sea-water? a certain part of a tidal river the amount of Sodium Chloride is 57 per 100,000, the average proportion of Chlorine in the fresh-water, sewage, &c. that find their way into it is 2 per 100,000; find the proportion of sea-water in the total volume of the stream at the place and time of observation.
3. A circular ward with a dome-shaped roof requires to be measured. The diameter is 36 feet; the height to the centre of the roof is 18 feet, and the height of the walls is 12 feet. Find the floor space and total cubic contents. How many patients would you put in such a ward?

5. What principles must be followed in the construction and ventilation of House Drains? If a 9 inch drain with a fall of 1 in 200 gives a velocity of 3 feet per second, what fall must it have to give a velocity of 6 feet per second, the drain running half full in each case?
6. An outbreak of disease takes place in a town of 57,000 inhabitants; 1340 cases occur in 29 days, and of these 712 die; what are the proportions of cases and of deaths per thousand of the population for the period, and also per annum at the same rate?
