780 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 
DESCRIPTIONS OF SPECIMENS AND ANALYTICAL DETAILS. 
The details of the analysis which follow contain the description of 
the samples and the details of the determinations. They are arranged 
in the order previously named, the specimens of each species being in 
the order of the laboratory numbers. 
The description of the specimens of oysters and clams do not say, 
except in a very few cases, whether they were or were not u floated,” i. e 
placed for a time in brackish or fresh water after removal from the beds. 
As the practice of floating is so universal, and as the specimens were 
received in the condition in which they are usually sold, it is probable 
that the majority, if not all, of the specimens, with the exception of 
those in cases specially referred to, had been floated. 
The following data have been compiled from our laboratory note- 
books, as was done with the analyses of fishes:

Transplanted to New Haven, Connecticut. The specimen consisted of 30 oysters in 
the shell. An accompanying letter says: “From James River, Va., * * * are 
what we consider the best stock to plant; * * * have been planted here five 
weeks.” Though not distinctly stated, the probable inference seems to be that the 
oysters were floated, like No. 72. Specimens taken from the same bed were analyzed 
five and one-half months later, October 31, as Nos. 82 and 83. 
72. Oysters. Rappahannock River, Virginia. Furnished by Mr. Lane, New Haven. 
In an accompanying letter Mr. Lane says: “ * * * From Rappahannock River ;

into floats for forty-eight hours to fatten them.”
