4A ADDENDA. 
In Muller’s opinion, it is not an infufion ani- 
malcule, ‘ though its proper abode is among 
‘them, on the water lentil. The figure and 
“number of feet approximate it to the genus of - 
“mites or acari; and although neither eyes nor 
© antenne are perceptible, the other parts induce 
* us to clafs it with infects.’ 
He proceeds: * Three claws terminated each 
‘foot ; fomething like eggs were feen within. 
“Sometimes I found a fimple fkin with the feet, 
“nails, and eggs. This is not a dead wr/let, but 
‘a flough, fuch as other animals throw off; but 
* how does the ovary come here ?” 
The figure in the Archives, Plate 36, feems 
very correct. If we may judge from what is faid 
in the account of it, this animalcule muft have 
been a great deal larger than mine. 
Whether it belongs to the clafs of infeéts may 
be doubted: if it does, I fee few reafons why 
Spallanzani’s does not belong to Jit alfo.---It is 
very probable, that feveral of what we call infu- 
Jion animalcula, are only miniatures of fome larger 
animals.---Thofe of the northern nations have 
alone been inveftigated ; it is reafonable to ex- 
pect new animalcula as well as we find new ani- 
mals
