Analysis of Water from Buckman’s Springs. 107 
ANALYSIS OF WATER FROM BUCKMAN'’S 
SPRINGS. 
In 1879 the editor of the SCIENTIST first visited the canyon 
where are found the delightful mineral springs, well known in 
San Diego county as Buckman’s soda springs, situated some ten 
miles north of Campo and fifty miles east of San Diego. 
During a two weeks pleasure trip in July we again visited this 
resort and were favored by our friend,the proprietor, with the 
following analysis of the water from one ot the many springs, 
which analysis was made by Mr. George E. Colby at the Uni- 
versity of California, and was endorsed as correct by E. W. Hil- 
gard. 
“The water is only very slightly turbid and tastes strongly 
pungent from the presence of free carbonic acid gas, of which it 
contains 418.2 cu. in. per gallon, keeping in solution the sub- 
stances marked with an asterisk (*). 
“On evaporation the water yields a solid residue at the rate of 
119.33 gains per gallon; of this amount 11.80 grains is chemi- 
cally combined water, with a very small quantity of organic mat- 
ter, which is driven off by ignition, leaving 107.53 grains of 
strictly mineral matter, of which 62.38 grains was again soluble 
in water, 45.15 grains being insoluble. 
‘‘The composition of the residue is as tollows:—

Physicians unhesitatingly recommend the use of this water, 
and it has often proved very beneficial in cases arising from impure 
blood and debility. As a pleasure and health resort these 
springs are destined to become widely and favorably known. 
TO WORKING ENTOMOLOGISTS. 
Mosquitoes and house flies are perhaps the most numerous, 
widely distributed and persistent of the creatures that attack the 
health and comfort of human beings. Of their attacks upon our 
comfort every one is aware. Scientific investigation favors the 
belief that tuberculosis and ophthalmia are carried from deseased 
persons to healthy ones by the house fly, and German experi-
