23 Cutis, is compos'd of a Congeries of Membranous Fibres , inter- 
rnixt wirh a great many Capillaries , and endued with Pores fit for 
Perfpiration : And there are Anatomifts who afiert, they have 
inje.ded thefe Cutaneous Veflels in the Cuicula of a Fatus , as well 
as in the Cutis tho’ when the Animal is more adult, thefe Capil- 
laries not only efcape the view of the naked Eye. but even of 
Opticks. That this has been the Strudure of the Cuticula in this 
Animal, is molt plain and obvious ; for tho’ I cannot determine 
its thicknef , as Dr. Afoul'ws might have done in a recent One, 
yet now as it is dry, it feems to be of the thicknefs of, or ra- 
ther thicker, than common Vellum, with its inner Surface exca* 
vated, as you fee a Woman’s Thimble, (the Holes being much 
about the fame Bignefs, and difpos’d regularly) or in an Honey 
Comb. Among the Interfaces of thefe Excavations, the Rami- 
fications and Divarications of the Blood VefTels are obvious. At 
A- every two Lines or \ of an Inch diftance, for the moft part are to 
be obferv’d Protuberances compos’d of 5, 6, or 7 Columns joining, 
and making up a Pyramid or Cone ^ in the top whereof is the Pore 
or DuUm, mention’d by Dr. Moulin s, through which the Hair's 
pafs; they are nothing but the lnterftices of the Favi, (fo to call 
them) or Depreffions. which arife in the Cuticula , and are im- 
paded in the Cutis , for the better Reception of the Hair. And 
dis probable, that all the Hairs are cover’d over with thin Mem- 
branes, as Dr. nJWoulins obferves, from the Extremity of their 
Roots to the Cuticula j becaufe having pull’d out feveral of the 
Hairs, I faw them included within their proper Involucra , and. 
doubt not but it was fo with all the reft too, befide the common 
one which is both contiguous and continuous to the Cuticula . 
The Hairs are more loofe, and the Pores more patulent and ob- 
vious in the Cuticula now dry'd, than I fuppofe they were when, 
recent ; but whether thefe Pores were alfo defigned for Separa- 
tion of Vapours by. Perfpiration, or only to contain, and con- 
vey the Hairs planted in the Cutis through the Cuticula, is what 
, Q : I fhall neither contradid not affirm. To the outfide of this Cuti- 
^ cnla are adherent the Scabs, which I rather take to be a Super- 
venient Diftemper incident to this Animal, when out of its own 
Climate, occafion’d by the Conftridion of the Pores from Cold, 
than any wife Natural to it : And to this the Accounts of all 
Authors agree-, who tell us, that there are two kinds of them, 
one of a more dark Colour, and another duskifh and fad, ha- 
ving both their Skins of a very fmooth and polite Surface $ where-
