186 REPORTS ON THE STATE OF SCIENCE.—1912. 
A. Organs of Jacobson.—In this specimen these were represented by 
a shallow depression only on the left side, while on the right side there 
was a short tube about 5 mm. long, running just under the surface 
backwards from the hinder end of the depression. 
B. Hairs on wpper part of snout.—These were more numerous than 
in the adult, and were arranged in a slightly different way. The actual 
relative positions of the hairs in this specimen are shown in fig. 5. 
Occupation of a Table at the Zoological Station at Naples.— 
Report of the Committee, consisting of Professor S. J. 
Hickson (Chairman), Mr. E. §. Goopricn (Secretary), 
Sir E. Ray LANKEsTER, Professor A. SEpGwicKk, Professor 
W. C. McIntosH, Dr. S. F. Harmer, Mr. G. P. Brpper, 
Mr. W. B. Harpy, and Professor A. D. WALLER, appointed 
io aid competent Investigators selected by the Committee to 
carry on definite pieces of work at the Zoological Station at 
Naples. 
Since the last report of the Committee was written, Mr. W. O. 
Redman King occupied the table until the end of August 1911; Hon. 
Miss Mary Palk from November 5, 1911, until March 28, 1912; and Mr. 
C. H. Martin from May 10 to May 21, 1912. Short reports of the 
work done by Mr. Redman King and Mr. C. H. Martin during their 
stay in Naples have been received and will be found below. 
During the past year the Zoology Organisation Committee of the 
British Association have made efforts to secure a permanent endow- 
ment for one or more British tables at the zoological station at 
Naples, but so far without success. That Committee will continue its 
work in this matter during the coming session. 
The Naples Committee ask to be reappointed with a grant 
of 5OL. 
Mr. W. O. Redman King reports: ‘I occupied the British Asso- 
ciation table at Naples for about eleven weeks during June, July, and 
August 1911. During this time I investigated the temperature 
coefficient of development of the sea-urchins Spherechinus and 
Arbacia, over 1 range of temperature from 10° C. to 30° C. The 
coefficient for Arbacia turned out to be appreciably higher than that 
for Sph@rechinus: the values were about 3.0 and 2.8 respectively. 
The work has not yet been published, as I wish to amplify the results 
and extend the experiments to other forms.’ 
Mr. C. H. Martin reports: ‘I occupied the British Association 
table from May 11 till May 21. During this time I examined thirteen 
Boxboops, and I had an opportunity of confirming my former observa- 
tion that the so-called Trypanoplasma intestinalis (Leger) is not really 
a Trypanoplasma, since it possesses three free flagella at its anterior 
end. I was able to find a further series of division stages and (a 
point which is T believe of some importance) a series of stages which
