of no advantage to the body, yet it is able to 
raife our thoughts to God; fo that by ferioufly 
contemplating the divine Majefty, and the 
glittering rays of his miracles, in this little 
animal, we may, with the moft fubmiffive 
humility, change and contract our vain pride 
into as {mall a point. 
Then we fhall obferve the finger of Godin 
thefe things, and fhall obtain an effet, which 
none of the forcerers can imitate, or reduce 
into ad: for the moft fmall and humble 
may drive away the devil, and rob him of 
his ftrength. 
The miracles of God are magnificent in 
every thing he has created; and even the 
fmalleft of them are the hoft of the Lord of 
The BOOK of NATURE; or, 
Ifrael ; wherewith he does fervice to his peo- 
ple by chaftifing them, when their fins are 
grown to an height; that they may repent 
and acknowledge the fupreme hand, which 
punifhes our offences, as we are taught at 
large in the facred writings. I thall conclude 
this difcourfe with obferving, and fhall always 
firmly maintain, that the miracles of nature 
are open books, whereby we are all reduced to 
our eternal origin, nor are we ever elevated 
above nature and created beings, until we 
conftantly love God, and renounce all that is 
not God. 
The end of the wonderful anatomy of the 
Laoufe. 
Dorey Ba aly 
Explains the changes of the firft order or clafs, which are laid before the eye, by the affiftance of 
Jigures ; for which purpofe the Loufe is produced for an example. ‘ 
N. B. The humeral letters diftin@ly fhew; after what manner the tranfmutations fucceed 
each other: fome of the figures are exhibited as they are magnified with the microfcope; 
and let the reader obferve in general, that we have likewife followed the fame rule in 
the examples of the fecond, third, and fourth orders or claflés of our changes of infeéts. 
No. I. Is the Nit or little egg of the Loufe 
delineated in its natural fize, wherein the 
Loufe is contained, being yet cloathed in its 
firft coat or skin. ‘The fame may be feen in 
fig. 1. as magnified with the microfcope. 
Il. The empty fhell of the egg, or the 
Nit’s coat, caft off by the Loufe, after it has 
crept out of it. It is reprefented magnified 
in fig. 11. 
Ill. The Louée itfelf juft excluded from its 
ege, or coat, where it is evident, how this 
animal has crept out of the membrane where- 
with it was covered, in a ftate of perfection 3 
fo that it is not obliged to undergo any other 
change, but afterwards grows to a larger fize, 
and muft often change its skin. Wherefore 
we have called the Loufe in this form, an 
oviform Nymph animal; becaufe it comes 
from its coat perfect in all its members. 
IV. We reprefent the fame Loufe fome- 
what larger, and cloathed as it were in its - 
third or fourth skin, which is likewife to be 
caft off foon after. 
V. The Loufe, having attained the full 
term of its increafe ; in which period we have 
confidered it as a Nymph animal ; becaufe it 
is then in the laft skin that it will caft, and 
indeed we find fome infects in this firft order, 
which are ftill fomewhat changed about the 
time of cafting their laft skin ; which is fufh- 
ciently evident, among other examples, in the 
longipede or long-legged Spider; the legs of 
which grow much longer, at the time it is 
cafting its laftskin. After this is caft, the in- 
fe&ts of this firft order grow no more, nor 
— are they any ways changed ; as may be more 
eafily underftood from the figures of the fub- 
fequent examples of the four orders, under the 
fame numbers v and vi. ) 
VI. The Loufe, having attained its perfect 
maturity and full growth, {fo that is now fit 
for generation, and is arrived to the ftate of 
puberty. Fig. 111. reprefents it magnified by 
the microfcope. Si . 
Fic. 1. 
The Nit or egg of the Loufe delineated with 
a microfcope. 
@. An oviform border or extremity, which 
furrounds the Nit’s head; within which are 
feen certain {mall cups, likeuvule, of no exact 
or determinate figure. ‘Thefe little cups are 
fomewhat bent, and they again fwell in the 
middle, as it were into a whitifh top. It is 
obferved alfo that thefe little cups do not in- 
tirely fill the inward parts of the border or 
circle that furrounds the head. 
bb. Two tender little fwellings or pimples, 
wherein the Loufe’s eyes, whilft its limbs are 
yet moift and foft, are fituated. Thefe eyes 
grow infenfibly browner, and become vilible 
through the fkin, and at length grow entirely 
black. 
c. A certain white pellucid little part, fitu- 
ated in the middle of the Nit, which we have 
often obferved to beat regularly like the heart ; 
and this is the little part reprefented by the 
letter 4. in figure v1. and called by us the 
pancreas, as it moves up and down with the 
ftomach.
