suit water, aiul that it is for tliis purpose they emigrate in autumn 
to the sea. Considering the immature condition of tlio Eels when 
they begin to emigrate, their development in salt water must he 
exceedingly rajiid, and it is probable tliat the process is so exhaust- 
ing that both males and females die soon after spawning. This 
would account for their not being seen returning from the sea. 
'I’he Eel known to us as the Eroad-nosed Eel, which is found in 
})onds, and does not migrate, is said to bo the barren female ; the 
.Shai'[)-nosed Kel is the fertile fish, which on its seaward migration 
is intercepted by the iixed engines of the iishermen, there being a 
slight difference between the two sexes, which is appreciated by the 
fishermen. 
A paper on “ Varieties of Sugar,” natural and artificial, was com- 
municated by myself. It was hastily put together, but it occurred 
to me that at the present time, when sugar is being produced both 
naturally and artificially in ipiite astonishing (piantities, the subject 
would be of interest to the ^lembers, and I believe this result was 
fulfilled. The paper will be lu'inted in full. 
I also contributed a paper on “ AVater from a AVell at Kirby 
I’cdon,” which has produced some little excitement among geologists, 
inasmuch as it reveals a condition of things unknown in this 
district ; that is to say, a water of abnormally high temperature, and 
containing very large proportions of iron, sulphuric acid, and 
magnesia, and no carbonate of lime. As the discussion on this 
paper is postponed to the next meeting, I will refrain from further 
mention of it. 
Air. II. B. Woodward has contributed an addition to his paper 
on “ Earthquakes in Korfolk,” in which he has given an account 
of that which occurred in April, 1884. Air. Power has given us 
notes of the “Autumnal Aligration of Birds,” observed by him at 
(dey; and Air. J. II. Gurney, Junr., a paper on the same subject, 
in which he has drawn iqi a comparative table of simultaneous 
migration to Heligoland and to England. 
Air. Bridgman read notes on a Wasps’ Xest at the February 
meeting, describing the AVasps and their cells, and also the parasites
