the saltness increased to 14° Baume in the summer of 1872, and 

 25°, in August, 1874, The changes in the species were then first 

 noted. The author afterward corroborated the fact by experiments 

 on Artemioe reared in captivity in water of which the saltness was 

 gradually increased. A change also takes place, correspondingly, 

 in the form of the hranchise, and in the number of apodal segments.

III. ASTEONOMY. 



1. Astronomical and Meteorological Observations tjiade during 

 the year 1873, at the U. S. K Observatort/, with Appendix ; li ear- 

 Admiral B. F. Sands, Superintendent. Gov. Pnnting Office. 



This volume contains the record of a year's work at the Obser- 

 vatory, and is evidently the record of first rate work. The Appen- 

 dix by Professor Newcomb has been already noticed in our Feb- 

 ruary Number. 



If the use for several years of one value of the latitude of the 

 Observatory for reducing observations, made by the mural circle, 

 and of another value for observations made by the transit circle, 

 were the deliberate choice of the Superintendent, astronomers would 

 probably think his decision unwise. The same also must be said of 

 usmg a different latitude each year for the final tables of north 

 polar distances, derived from the observations of the transit circle. 

 It would also look better, to say the least, if the results were given 

 111 the same denomination, instead of north-polar distance for one 

 instrument, and declination for the other. 



These things look not so much like the deliberate choice of the 

 Superintendent, as the kind of little irregularities that must be ex- 

 pi-cted from a system that makes little account of scientific fitness 

 Hi appointing the Superintendent of a scientific institution. AVe
