PRESCOTT, ON TOBACCO. 251 
abdomen carry little waving hairs (ci/éa) at their tips, and are known as 
ciliated epithelium. 
“The result of the investigation left no doubt remaining that with that 
knife the ¢hroat of a living human being, which throat had been protected 
by some coéfoz fabric, had been cut. The accumulation of evidence was 
fatal to the prisoner, who without the microscopic testimony might have 
escaped. 
* But what was there in the dried brown stain that determined it to be 
blood? And, particularly, how was it proved not to be the blood of an ox, 
as the prisoner averred? ‘To these points we will now give a moment’s 
attention.” 
_ We might add a large number of extracts such as these, 
but enough has been given to show the way in which Mr. 
Gosse treats his subject. The work is copiously illustrated 
with woodcuts, the majority of which are from Mr. Gosse’s 
own drawings. The woodcuts are perhaps a little coarse, 
but they appear to be faithful representations of the objects 
described. We can recommend Mr. Gosse’s book as a very 
pleasant companion to the microscope. 
Tobacco and its Adulterations. With illustrations, drawn and 
etched by Henry P. Prescott, of the Inland Revenue 
Department. London: Van Voorst. 
Many substances used for the adulteration of articles of 
commerce, which formerly defied all kinds of investigation, 
are now easily discovered by the aid of the microscope. The 
medical man was the first to apply this instrument in the 
detection of fraudulent adulterations of food and medicine. 
The Government has been slow to appreciate its use in the 
cases where it might have been employed to detect fraud on 
taxed articles of consumption. We are, however, glad to 
be able to congratulate the Inland Revenue department on 
the possession of an officer who is so capable of appreciating 
the value of microscopic aid in the detection of adulterations 
as Mr. Prescott appears to be. It has been long known 
that chemistry is of little service in detecting the adulteration 
of tobacco. In fact, for many years, it seems, that instead 
of chemistry detecting frauds in the adulteration of tobacco, 
it was the unintentional source of fraud by the Government, 
who fined tobacconists for having tobacco in their possession 
which contained sugar, when it afterwards turned out that 
all tobacco naturally contains a certain quantity of sugar.
