CONTINUATION OF ACCOUNT OF CllYPTOPIA. 
in liis analysis of the juice, and that he, De jMachy and Errhardt^' mention 
nitric acid as one of its constituents. I have carefully examined the ash left by 
the combustion of the extract, and find myself in agreement with Bertrand and 
Baume in being unable to discover a trace of nitrates. 
Vapor Conice .—The use of the extract in the formation of the vapor is ob¬ 
jectionable, for two reasons : first, the quantity of conia contained in the portion 
of mixture prescribed, is too small to relieve spasm ; and, secondly, any influ¬ 
ence which a minute portion of the a.lkaloid might possess, would probably be 
more than neutralized by the simultaneous evolution of ammonia from the 
alkalized extract. 
In the followdng form these objections do not exist, and the dose of conia can 
be readily graduated :— 
Conia, 1 grain. 
Alcohol, fluid drachm. Dissolve the conia in 5 ss of the alcohol, and 
add the remainder mixed with the water. 
Water, 2^ fluid drachms. 
20 minims contain of a grain of conia.

The analysis of Cryptopia will be considered a valuable addition to the paper 
published in April on that alkaloid. Through the kindness of our friend Dr. 
Cook, Demonstrator of Chemistry, King’s College, we are enabled to subjoin 
the following analytical results:— 
ANALYSIS OF CRYPTOPIA. 
C:=12. 0 = 16. 
The alkaloid, dried first under the air-pump for some hours, and then in a 
water-bath kept at a temperature of 212 ° F., lost no weight. 
I. 3’26 grs., burnt wdth oxide of copper, with a layer of metallic copper 
turnings in front, gave 8 33 COo and 1-98 lUO, equal to 70’00 per cent. C 
and 6-77 per cent. II. 
II. 4*7 grs., burnt in the same manner, gave 12*08 C Go and 2-88 equal 
to 70*2 per cent. C and 6*8 per cent. H. 
III. 5*32 grs., burnt in a similar manner, gave 13*{)6 C Oo and 3*15 II 2 O, 
equal to 69'5 per cent. C and 6*76 H, 
IV. 6*45 grs. alkaloid, when burnt with soda-lime, and the ammonia absorbed 
by standard acid, which contained 20*96 grs. SO 3 per 1000 fluid measures, were 
found to have neutralized an amount of acid equal to 28 measures = *2054 N 
= 3*77 per cent. N. 
Y. 5*9 grs., treated in a similar manner, were found to have neutralized acid 
equal to 30 measures = *22 N = 3*73 per cent. N. 
The above figures indicate the formula (C „3 lUg NO 5 ).
