VARIATIONS IN QUALITY OF COMMERCIAL CHLORINATED LIME. 231 
Want of time has prevented me from obtaining more than seven samples 
for examination. 
These samples were purchased as “ best olive oil,” from different localities ; 
the price paid varied from 1 d. to 2d. per fluid ounce. 
The general result proves that olive oil is subject to extensive adulteration, 
and that the sale of adulterated oils, though principally confined to the 
poorer districts of the Metropolis, is not altogether absent from neighbour¬ 
hoods of higher respectability. 
The instrument and conditions under which these tests have been taken, 
are precisely the same as those mentioned in my former paper. I shall, 
therefore, proceed to describe the samples at once. Sample No. 1 was ob¬ 
tained from a dispensing establishment in the City ; No. 2 was obtained from 
a “ small retail ” in Fleet Street; Nos. 3 and 5 were procured from the New 
Cut, Lambeth; No. 4 was supplied by a chemist, who confessed to having 
other qualities of olive oil; sample No. 7 was purchased in Waterloo Road; 
No. 6 was taken from a flask of salad oil, supplied by a respectable oilman. 
In colour these samples varied but slightly from each other. They pos¬ 
sessed marked differences in smell; No. 5 having a decided odour of cotton¬ 
seed oil. When strongly agitated with an aqueous tincture of litmus and 
allowed to stand fora few minutes, No. 1 indicated a strongly acid reaction, 
which was scarcely perceptible with No. 4. The other samples, treated in a 
similar way, gave no differences of result, the colour of the tincture being 
nearly unaltered.

From the deportment of samples 5 and 7 under the action of prolonged 
contact, I have no hesitation in stating that they contain either oil of poppies 
or cotton seed oil, and from their low resistances it is very certain that the 
adulterating ingredient has been very liberally added. Sample No. 3 differs 
in its behaviour from 5 and 7, and I am, therefore, inclined to believe that a 
different material has been employed in its adulteration. Samples 1 and 4 
are decidedly genuine. No. 7 is probably a mixture of olive oil and highly 
refined cotton-seed oil.

Although I must apologize at the outset for the crudeness and brevity of 
the succeeding observations,—a result in some measure attributable to the very 
great difficulty of obtaining by my own unaided endeavours a sufficient
