OBSERVATIONS. 
First Age. 
The silk-worms, on some tables or hurdles, roused sooner than others; by reason of the exterior cold, 
the temperature of the small Laboratory was. in some parts, a degree and a half below other parts, although 
the whole Laboratory was well closed, and lined to keep out the cold. This degree of cold was on the side of J 
the apertures, and lower rows of tray hurdles. 
Second Age. 
The silk-worms became torpid and roused with more regularity, and at less distant periods than in the 
first age. 
All proceeded with regularity in this third age. 
There were twenty-four pounds more of mulberry leaves consumed this year than in 1813. 
There was less refuse picked from the leaves in 1814 than .in 1813, consequently^ the average quantity 
of leaf must have been nearly the same both years. 
Fourth Age. E 
Two days were employed in cleaning the wickers, because the silk-worms that were placed in the'coolest 
part of the Laboratory, became torpid, and roused a whole day later than the others. 
Thirty pounds more of sorted leaves were consumed than in the year 1813, but in 1814 there was lesB 
refuse. The progress of the fourth age was tolerably regular. 
Fifth Age. 
The cold, and variableness of the weather, render these last eleven days of the'season remarkable. 
The silk-worms continued to prosper. But as the nights were very cold,^an even tcmpcrature]equal 
throughout every part of the Laboratory could never be obtaioed. Fires w'ere lighted in the stoves, and thick 
wood was burnt in the grates, to maintain the necessary temperature. 
There were eighty-four pounds more of leaves consumed than in the year 1813. 
The refuse of the leaves and the weight of dung were less than in 1813. 
There were fewer mulberries ou the branches, and ever, those were lighter in 1814, than in the preceding 
seasons. There were obtained six pounds more of cocoons. Some wicker hurdles required a little leaf on 
the '29th of June, the thirty-eighth day of the rearing of the silk-worms, aud 'they received that which had not 
been consumed the preceding day. 
16S| Pounds of leaves per ounce of eggs. The silk-worms of five ounces of eggs having consumed 8130 
pounds of leaves, produced 601 pounds 8 ounces of choict cocoons, and 4 pounds 8 ounces of offal. About 
SKpounds of leaves were consumed for a pound of cococus.
