[1] A number of Kamel's treatises were published in the Philosophical Transactions, while his descriptions of Philippine flora appeared as an appendix to the third volume of John Ray's Historia Plantarum.

[2] His pharmacy has been minutely restored and still exists in the local Museum of Český Krumlov[3] During this time, Kamel applied to be sent to the Jesuit overseas missions and his request was granted.

He exchanged letters, information and specimens with Willem ten Rhijne, a Dutch botanist in Batavia; Samuel Browne and Edward Bulkley, two English surgeons in Madras; and two members of the Royal Society, the apothecary James Petiver and the naturalist John Ray.

[8] Kamel drew, described and commented on diverse parts of Philippine nature: from plants to animals, from minerals to insects, shells and molluscs, snakes and even monsters (see below), with his first known text published in 1699.

Although the first consignment of his treatises fell into the hands of pirates and was lost, he successfully shipped his accounts to London where they were published by his correspondents Ray and Petiver.

Kamel's descriptions of Philippine herbs, shrubs and trees were published as a 96-page appendix to Ray's third volume of Historia Plantarum (1704), while the remainder of his works appeared the Philosophical Transactions.
