bers, and there is an egg deposited in each of them, 

 with the quantity of paste necessary for the young. 



(>. These various kinds of work require in general less 

 skill and genius than labour and patience. There is a 

 very different degree of art and sagacity displayed in the 

 nest constructed by another fly with single pieces of 

 leaves only. This nest is a real prodigy of industry. 

 When it is taken to pieces, and nurrowly examined mail 

 its parts, one cannot conceive how a fly should be able 

 to cut them out, turn, and put them together with so 

 much propriety and exactness. When viewed on the 

 outside, this nest very much resembles a tooth-pick 

 case. The inside is divided into several little cells, in 

 the form of a thimble, set in one another as thimbles are 

 in a tradesman's shop. Every thimble consists of seve- 

 ral pieres. which are separately cut from one leaf, and 

 whojc form, circumference, and proportions tally with 

 the place each is intended to occupy. The same me- 

 thod is used with respect to" the pieces that form the 

 case or common cover. In a word, there is sr> much 

 exactness, symmetry, uniformity, and skill iu this little 

 master-piece, that we should not believe it to be the 

 work of a fly, did we not know at what school she learnt 

 the art of constructing it. We may naturally conjec- 

 ture that each thimble is a lodging for a little one ; but 

 we could not have imagined that the paste which the 

 mother provides for it is almost liquid, and that the little 

 celt, which is entirely composed of small pieces of leaves, 

 is notwithstanding a vessel so well closed up, that this 

 paste never spills, even when the vessel is stooped. 



Many brutes act in concert with each other. A 

 drove of oxen is grazing in a meadow: a wolf appears: 

 they immediately form into a battalion, and present 

 their horns to the enemy. This warlike disposition dis- 

 concerts him, and obliges him to retire. 



In winter, hinds and young stags assemble in \\erds, iu 

 the more numerous companies as Hie season happens t<> 

 prove severe. They warm each other with their breath,
