LIVERPOOL CHEMISTS’ ASSOCIATION. 
through the water for about two hours he did not see any diminution in size, and on 
taking the sp. gr. it was only 1’008. Notice was then taken of the process patented by 
Dr. Dewar, of Kirkcaldy, for the preservation of provisions, more especially fish and 
butcher’s meat, by means of this acid. The outline of the process is as follows:—The 
substance to be preserved is subjected to the action of the acid by immersion for a longer 
or a shorter time, according to its size, it is then, with as little delay as possible, sub¬ 
jected to a high temperature (not to exceed 140° F.), so as to preserve the albumen in 
the meat in a desiccated and not in a coagulated state, it is then redissolved by ample 
moisture with water. A specimen of fish and meat preserved by this process was shown, 
a quantity of which, along with several others, was sent by Dr. Dewar to Abyssinia 
with the late expedition, and they all kept perfectly fresh, being eaten by the troops on 
their return from Magdala. Linimentum Pot. Iodidi c. Sapone was then noticed; he 
stated that it was a troublesome preparation to keep, as it separated in cold weather, but 
on gently warming and shaking up, it went all right. Syrupus Ferri Iodidi was then 
noticed, and a reduction in the quantity of sugar ordered suggested, namely, from 28 
oz. (the P. B. quantity) to 26 oz., substituting 2 oz. of water, as this was the strongest 
syrup that would keep. He exhibited specimens prepared with 28 oz. and 27 oz., both of 
which had crystallized. The specimens had been prepared for fifteen months, during 
which time they had been exposed to the ordinary light of a room, he was therefore in 
favour of the plan in the retail trade of putting up the syrup in bottles, such as they 
were in the custom of selling, as he thought this proved that it kept perfectly colour¬ 
less when kept in bottles quite full. Syrupus Ferri Phos. was next noticed, and as an 
improvement, it was suggested that the 4£ oz. of diluted phosphoric acid ordered in 
the Pharmacopoeia be evaporated to 1^ oz., and the phosphate of iron previously well 
pressed dissolved in this, then filtered into 12 oz. by weight of the simple syrup of the 
P. B., finally washing the filter with 6 drms. of water which made up the measurement 
to 12 fluid ounces. Or instead of evaporating the diluted acid, in making the phosphoric 
acid according to the P. B., instead of diluting it to 20 fluid ounces, to dilute it to 5 oz. 
1 drm., or until the sp. gr. is 1'300; 1£ oz. of this is equal to 5£ oz. of the P. B. acid. 
He thought this process better than the P. B., as the syrup was much more quickly 
made, and the iron solution was not exposed as in dissolving the sugar in the diluted 
acid, which was a very tedious process without the aid of heat. Several other pre¬ 
parations were noticed, also the Sulpho-carbolates, and a specimen of the Sulpho-car- 
bolate of Soda, prepared according to the directions in the Pharmaceutical Journal, was 
exhibited. 
The Secretary said that it would probably be an advantage to use Bunsen’s filter in 
preparing phosphate of iron, as it could thus be filtered and washed in a very short 
time, and oxidation would be avoided. 
Mr. Abraham, jun., said that by passing the current of sulphurous acid very slowly 
he had obtained a solution of full strength. 
Mr. Tate proposed a vote of thanks to Mr. Hilditch, which was unanimously carried, 
and the meeting closed. 
Fifteenth and concluding General Meeting, held May 27th, 1869; the President 
in the chair. 
Mr. Arnold Milson, Albert Road, Southport, was unanimously elected an Associate. 
Mr. Tate suggested that at the half-session members should be received at half the 
ordinary subscription. This was the practice in some of the societies in the town, and 
he believed that many would thus be induced to join the Association, who had neglected 
to do so at the beginning of the session. 
The suggestion was favourably received; Mr. Tate promised to move an alteration of 
the laws to this effect at the Annual Meeting. He also exhibited a sample of lubri¬ 
cating oil made from mineral oil, and introduced Mr. Duncan, who described the merits 
of the oil, and its mode of preparation. 
The President then read his Valedictory Address. 
He observed that at the commencement of the session, he had referred to the present 
and future state of chemists and druggists as a body, in relation to their altered position 
with regard to the public and the Legislature, and also to the arrangements made for 
the opening of classes for the benefit of their apprentices and assistants, in enabling
