CLIMATOLOGY.

In a State which presents such a diversity of soil, of climate and of altitude as our own, the study of climate as related to disease is most important. The relation, too, of the long extent of sea-coast and the diverse character of our rivers and lakes, cannot be too carefully considered. Practitioners of medicine who are located in one section for a score of years, come to know much as to these local influences. They are often able, within the area of their own ridings, to point out the effects of geological strata or drift of rivers, ponds or the soil of waterlevel, of winds and of hills, woods and valleys, and so to estimate how to secure changes of climate without distant removal. We ask such to carefully study these tables of climate as related to disease, and in correspondence to add the results of their own observations. In the report of last year space did not permit a completion of the tables relating to the five years from July 1st, 1878, to July 1st, 1883. These will be added after the tables of this year, and will thus be available for reference and study. This report and the last will thus furnish a condensed weather table for five years. In reference, especially, to respiratory and malarial diseases, we think the careful student will be able to trace important differences in different localities of the State. We call attention to former articles in the reports on climatology, as these have so supplemented each other as to be an aid to the student. Our reports are mostly from the localities before chosen. On account of the removal of Mr. Richardson from Freehold, we have not a complete report therefrom. We miss, too, the accustomed hand of Hon. Wm. A. Whitehead, deceased, whose labors are of such value to all students of climatology, and especially to those in this State. We are indebted to the following observers:

VI. Vineland, John Ingram, M.D.

VII. Barnegat and Cape May, U. S. Signal Service.

VIII. Sandy Hook, U. S. Signal Service.

The tables of New York and Philadelphia are accessible for comparison. We may mention Lakewood, Atlantic City and Cape May as having shown advantages of winter climate that have been carefully recognized by many physicians and invalids. In summer not alone at our seaside, but also amid the hills of Morris, Sussex and Warren, and at some of the small lakes, there are found very desirable resorts.

METEOROLOGICAL SUMMARY OF VARIOUS STATIONS FROM JULY

1ST, 1883, TO JULY 1ST, 1884.

STATION, DENNIS LIBRARY, NEWTON, N. J.

Latitude, 41° 2′ 45′′ N.; Longitude, 2° 19' 48" E. Height of Barometer Cistern above Sea Level, 660 feet.

REMARKS.-1883, July-Frequent thunder showers occurring at night. Precipitation above the average. Duration less than one-half that of July, 1882. There were two days of entire cloudiness. Rheumatism, pneumonia and typhoid fever appeared during the month. August-Average temperature low, the mean of the maxima being 4.50 below the average for August. No rain from 24 to 16th. Heavy dews From 7th to 12th, winds were from points S E and N. E. During that period, a severe form of influenza appeared among families living near the low, wet meadows which lie northeast of the town. Frost on 27th Scarcity of water in wells Diphtheria prevalent at close of the month. Autumn, 1883, was nearly 1.70 below the average. Rain-fall deficient in September and November First killing frost on October 6th Ground frozen. Intermittent fever appeared. The northwest winds of November were frequent and disagreeable. Epidemic rose-rash appeared in the early part of the month. December was mild until the 16th. Then ten days of snow and rain, which left 10 inches of snow on the ground at the close of the month. The temperature on the 23d did not rise above zero the entire day. Remittent fever, fatal. The low mean humidity of the six months, July to December, is greatly in contrast with the corresponding period of 1882, which shows 80 per cent,, all of the months having a higher mean. The general health of the community has been good. 1-84, January-Daily range of temperature was normal; monthly range was 80 below the average. The month was steadily cold. Ground covered with snow and ice 31 days Dysentery appeared in latter half of the month February-Frequent fogs and mists. There were 171 hours of precipitation. Cellars flooded from the 15th to the 29th. Temperature of 29th unprecedented, average for the day being 6.00 Rheumatism and deafness prevalent. Winter, 1883-84, was 1.690 above the average. March-Memorable for the ice-storm of the 8th and 9th. Trees covered with ice five days. No abrupt changes in temperature until during the gale of 29th and 30th, there was a fall of 400 in 12 hours, temperature remaining below the freezing-point 24 hours. Cellars were flooded from 19th to the close of the month. Catarrhal fever and rheumatism appeared April-Cold, icy winds; low humidity. Scarlatina and diphtheria prevalent. May-First half wet and foggy. Ice formed on the 29th. June had a wider daily range than any of a series of seven years. Low night temperature. Rain-fall deficient. The yearly mean temperature was 0 290 low.
