the mercurial ointment being quite undesirable; taking 
the quantities given in the Pharmacopoeia, he agitated 
the ammonia with one-half the camphorated oil; rubbed 
the mercurial ointment with the other half, and mixed 
the two results together. A few minutes sufficed for the 
■operation, heat was not used, and the product was quite 
satisfactory. 
Mr. James Blair concluded his paper upon “ The Che¬ 
mistry of Calico Printing.” 
The paper was illustrated with photographs, charts, 
specimens of materials dyed and printed, and by experi¬ 
ments showing the effects of some of the processes em¬ 
ployed. 
[We purpose printing this paper in a future number.] 
At the conclusion of the paper, Mr. Blair replied to 
■several questions asked by those present, and after a 
short discussion, the President congratulated Mr. Blair 
upon the copious and strictly scientific manner in which 
he had treated his subject, and moved a vote of thanks, 
which was carried unanimously. 
GLASGOW CHEMISTS AND DRUGGISTS’ 
ASSOCIATION. 
Anderson’s University. 
The Fourteenth and concluding Meeting of the Session, 
Wednesday, April 19th, 1871; Mr. Thomas Davison, 
President, in the chair. 
A paper was read by Mr. J. L. Macmillan on “ Vola¬ 
tile Oils,” in course of which he called attention to the 
difficulty in testing these, and their liability to adultera¬ 
tion, stating that turpentine, from its resemblance in 
chemical composition to most volatile oils, was frequently 
used. He then referred to the specific gravity and blot¬ 
ting-paper tests, stating that while the latter answered 
for fixed oils, they were both unreliable tests in some 
cases, and suggested to the Council that a prize offered 
for a reliable test might bring out some satisfactory 
result. 
Mr. Kinninmont remarked that the adulteration of 
volatile oils was one which deserved attention, and he 
would recommend Mr. Macmillan to proceed in his in¬ 
vestigations. He said he had lately come across a sample 
of ol. lavand. which was adulterated with castor oil, and 
from its solubility in alcohol it was with much difficulty 
detected. 
Some remarks were afterwards made by Messrs. Pa¬ 
terson and Fairlie, and, on the motion of the Pre¬ 
sident, a unanimous vote of thanks was passed to Mr. 
Macmillan for his paper. 
The report of the Early Closing Committee was then 
submitted, and being considered favourable, the Com¬ 
mittee was instructed to take further action as soon as 
possible. 
Mr. Fairlie, Hon. Secretary, afterwards stated the 
arrangements that had been entered into with the “ Popu¬ 
lar Class Committee” of Anderson’s University, for the 
conducting of a botany class for students in pharmacy; 
about thirty names were given in, and Professor Hennedy 
had arranged to begin on Wednesday evening, April 26th. 
. The President, Mr. Davison, then delivered his Vale¬ 
dictory Address, in course of which he congratulated 
the . members on the importance of the position their 
Society had now attained. In referring to the early 
history of the Sooiety, he said it was instituted in 1854 
as an Early Closing Association, and, at the end of three 
years,_ having partially attained its object, it was re¬ 
organized into a Mutual Improvement Society. For 
man y years their only place of meeting was in a tem¬ 
perance hotel, but latterly, through the kindness of Dr. 
Moffat, they were permitted to meet in his laboratory, 
till last year, when the Council thought it desirable that 
some change should be made, both for the good of the 
Society and the trade. Negotiations were entered into 
with two of the scientific institutions of the city, the 
result being, that they were now located within the walls 
of a University. They h'ad still much to undertake, yet, 
however, before they could take the position they ought, 
he therefore counselled the members to greater diligence 
and perseverance in their studies. 
Mr. Ivinninmont, in proposing a vote of thanks to 
Mr. Davison for his services as President, remarked that 
he thought he (Mr. Kinninmont) was the only member 
present who had attended the first meeting on the early 
closing movement in 1854, and on looking back over the 
years that had intervened, he thought they had much to 
congratulate themselves on in the advance that had been 
made. Those present could have no conception of the 
struggles of these early years. He thought they had 
been exceedingly fortunate this session in the choice of 
President and Secretary, and to his mind the amount of 
work they had gone through was extraordinary. He 
trusted that the same energy would characterize all 
the members, that at no distant date we might see a 
school of pharmacy established in this important district. 
He had much pleasure in proposing a hearty vote of 
thanks to the President and Secretary, which was re¬ 
sponded to with acclamation. 
Messrs. Davison and Fairlie briefly replied, acknow¬ 
ledging the compliment paid them. 
The Secretary then called attention to the ‘ Register’ 
of Chemists and Druggists, which had been presented to 
the Association by the Council of the Pharmaceutical 
Society. 
The President, in moving the thanks of the Associa¬ 
tion to the Council for their donation, stated that Mr. 
Joseph Ince was engaged in preparing a book of auto¬ 
graph prescriptions for Glasgow, and. that it was ex¬ 
pected to be ready in May, when any member would 
have an opportunity of examining the collection. 
CHEMICAL SOCIETY. 
April 2 Oth .—Professor Odling, F.R.S., Vice-President, 
in the chair. 
The following gentlemen were elected Fellows : C. C. 
Grundy, S. B. Lee, G. Sutcliffe, W. Ward. 
Mr. C. Haughton Gill read a paper “ On some Saline 
Compounds of Cane Sugar.” Peligot has described a 
compound of cane-sugar and salt, to which he ascribed a 
formula of C 24 H 42 0. 21 NaCl (C = 6H=*5 0 = 8), which 
requires 14-92 per cent, of sodic chloride:—this indicates 
the replacement of 9 parts of water by 58*5 parts of sodic 
chloride. Bondeau de Carrolles subsequently examined 
a similar compound to which he ascribed the formula 
C 24 H 20 O 20 , NaCl, 3HO, which includes water of crystal¬ 
lization of which Peligot makes no mention. Subse¬ 
quently Mitscherlich denied the existence of the body, 
and Hochstetter mentioned that other chemists had failed 
to obtain it. Mr. Gill, being at first unsuccessful in pre¬ 
paring Peligot’s compound by the method described, 
boiled a solution of sugar with an excess of salt for some 
time, filtered, and set aside the apparently uncrystal- 
lizable syrup. At the end of some months a few small, 
not very transparent, but individually distinct crystals, 
had formed. They were drained, rinsed, pressed and 
analysed. The numbers lead to the formula 2 (C 12 H 22 O u ), 
3NaCl, 4H 2 0. This compound of an unexpected com¬ 
position having been obtained, a number of solutions of 
sugar, with various proportions of different salts, were 
made up and set aside to crystallize. The salts employed 
were the chlorides of potassium, sodium, lithium and 
ammonium, the bromides of potassium and sodium, and 
the iodides of potassium, sodium, lithium and ammonium. 
In each case four solutions were prepared, having one, 
two, three and four molecules of the salt to the double 
molecule of sugar, 2 (C 12 H 22 O n ). None of the potassium 
salts gave compounds of a definite composition. The
