In these determinations the tea was taken as it is in commerce, without any attempt 

 to remove impurities. Calculating then from /filler's result for silica, the amount of 

 sanding would lie represented in my silica determinations by the excess of 4.35 per cent. 

 In the Japan sittings the sand as an adulteration amounts to 6.89 per cent, of the weighl 

 of the tea. 



The amount of extract, more than any other test, gives an insight to the real value 

 of the tea as regards strength, as this term is popularly used. 

 Percentages of extract were: 



Japan, best, 37.766

The small percentage of extract in some cases, indicates that the tea leaves were 

 partly spent, probably on account of being exposed to dampness in transportation; also, 

 the extract would be governed somewhat by the amount of sand present. 



It is very generally supposed that the cheaper teas contain mineral impurities, due 

 to the method of curing. I tested in two of the cheaper teas for Pb. and Cu., the sup- 

 posed impurities, but did not find either. 



In general it may be said, that though teas are often adulterated, the adulterations 

 are of a harmless nature, and generally governed in amount by the price. 



METEOROLOGICAL SUMMARY FOR THE YEAR 1883. 



PREPARED BY PROF. F. H. SNOW, OF THE UNIVERSITY OF KANSAS, FROM OBSERVA- 

 TIONS TAKEN AT LAWRENCE. 



The chief characteristics of the weather of 1883 were the low mean temperature of 

 all its months except April, November and December; the unusually long period of 

 immunity from severe frost; the large and well-distributed rainfall; the slight prepon- 

 derance of northerly over southerly winds; the high average wind velocity; the very 

 high mean barometer, surpassing that of any previous year of our sixteen years' record ; 

 and the remarkably brilliant and long-continued orange and crimson sunrise and sunset 

 glow of the last five weeks of the year. 



TEMPERATURE. 



Mean temperature of the year, 51.66°, which is 1.87° below the mean of the fifteen 

 preceding years. The highest temperature was 96.5°, on July 23d; the lowest was 14° 

 below zero, on the 22d of January, giving a range for the year of 110.5°. Mean at 7 

 \. m.. 15.76°; at 2 r. m., 60.42°; at 9 p. m., 51.66°. 



Mean temperature of the winter months, 27.10°, which is 3.12° below t he average 

 winter temperature; of the spring, 53.38°, which is .(11° below the average; of the sum- 

 mer, 73.20°, which is 3.17° below the average; of the autumn, 52.09°, which is .24° 

 above the average.
