Condor-grease is considered excellent for resolving and dissipating hard glandular tumours of the breast and other parts of the body; and the Peruvians attribute to it as many other virtues as the Europeans do to the kid, of which it is said by one of their physicians that _totus est medicamentosus_—all is medicinal. INSECTS. It is well known that warm and humid countries are infested with swarms of small insects, as flies, mosquitos, zancudos, fleas, &c.; and a certain traveller has asserted that, on this account, Lima was insupportable as a place of residence: but the statement is erroneous, for such insects do not flourish in the midst of population and cleanliness. Notwithstanding the mildness of winter in Lima, it is sufficient to annihilate the flies and zancudos: mosquitos are not within doors at any season of the year. The flies and zancudos multiply in summer; and the latter are very annoying, especially at night, for they prevent sleep by the buzzing of their wings. But by taking care that no water be left in the house till it become nearly putrid, this little insect will not be allowed to grow troublesome; for the zancudos are the offspring of the animalcules which are produced in water tending to a state of decomposition: neither do the flies prove troublesome by their numbers in the houses where cleanliness is not neglected. The pediculus may be said to be sterile on the coast, but most highly prolific in the Sierra: insects of this and the cimex kind persecute man wherever he sojourns, and Lima does not appear to be more infested or overstocked with such vermin than certain European cities. In Paris alone there are seventy-seven species of the cimex.[58]
