Dr. Walter Harris’s Methods of Treating Deathly Ill Children (Folger MS W.a.87)

By Victoria Kuhr

If your child was knocking at death’s door, wouldn’t you want to do everything in your power to cure them, even if the treatments were potentially dangerous? Folger MS W.a.87 (early 18th century) shows the great lengths parents went to cure their children of serious ailments. With several pages detailing strong purges for children based on Galenic theories of evacuative medicine, Folger MS W.a.87 is important because it records invasive treatments that were losing popularity in the mid- to late-17th century.

The recipes for purges in this manuscript are modeled after the treatments the eminent physician Dr. Walter Harris (1647-1732) used on his young patients. These include purges of children who were “pale,” “refused any kinds of Nourishment,” and suffered from “Vomitings, greene stooles, & gripnings [sic]” (Folger MS W.a.87., fol. 106, 108, 109). A prominent member of the Royal College of Physicians and frequent critic of Paracelsan and Helmontian medicine, Dr. Harris wrote De morbis acutis infantum (1689), translated into English as A Treatise of the Acute Diseases of Infants (1693),in which he records his observations of many seriously ill children successfully treated by his methods. Several of Dr. Harris’s observations were copied into manuscript W.a.87; several other pages of this manuscript seem to be translated or paraphrased from Harris’s work.

A Chile, 10 mounts ole breeding teeth, fall into a Losensse

& had 40 or 50 Stooles in a day, & was almost dead. I gaue her

dose of pouder, whith cousisted cheifly of Chalk & Coral, [e]ach

20 graines every fourth hour att l[e]ast, but in the begininning

I gaue itt oftner, till the Violence should abate; On the

third day I cleansed her body wh​​ith a Rubarb purge,

I repeated the same pouders 2 days more & reneued the

purges, & She was perfectly Cured.

(W.a.87, fol. 110, 150409).


In this observation, (also found on pages 122-124 of A Treatise of the Acute Diseases of Infants) Harris’s purge seemed to save the life of the ten-month-old child. Harris’s frequent administration of the dangerous powders contrasts with, for example, gentler purges attributed to Dr. Lour (possibly Dr. Richard Lower) in the cookbook of Hester Denbigh. Dr. Lour recommends giving medicine only “once in two days or twice in a day if need be” (NYPL Whitney MS 11, fol. 20).

The general procedure for purging children, recommended by Harris, is as follows:

The Evening before you give the purge, lett the Chile have

a Glyster of Milk and Sugar with a few grains of Salt.

If the Chile bee not restored to health & ease, Rest a day

and then give the pouders againe, as before, two days, & then

Give another purge then rest a day _ and so repeate the

pouders & purgnig 4, 5, or 6 times if need requires / –

(Folger MS W.a.87, fol 104, 150406)

This basic procedure is modified by Harris to suit the children’s different symptoms.

Purges were still common in the eighteenth century, but the purges Harris describes are only for worst-case scenarios in children whose last resort depended on an intensive cycle of clysters, powders, and cordials, followed by a day or two of rest. Although the powders vary based on the symptoms, they include ingredients such as crab claws, oyster shells, bezoar stone, similar to recipes for Gascoigne’s powder found in many recipe books (fol. 100-101). These ingredients helped to absorb the excess moisture which Harris believed was endemic to children: “The Nature of Children is moist and all Moisture is apt to degenerate into Sournesse” (W.a.87, fol. 100).

Other physicians believed the delicate nature of children would make routine preventative purges inadvisable which is no doubt why these recipes repeatedly stress the need for safety. Practitioners of chemical medicine thought it was important to find treatments that reduced a child’s discomfort level, instead of providing treatments that induced more pain. Gentler treatments included bathing infants in wine and stimulating a bowel movement by rubbing the stomach (Astury 87). According to historian of medicine Hannah Newton, “Johann Dolaus cautioned that ‘Children cannot bear Purging’” (70).  But when it comes to acute and potentially deadly illnesses, the author of W.a.87 copies Harris’s claim of “uspeakable [sic] Successe in Curing Children by purging Only which I practiced 7 years togeather” (Folger MS W.a.87, fol. 100). Practitioners may have considered all other options before intentionally putting a child’s body through further pain. However, when parents are desperate, these concerns may go out the window.

Physicians, such as Dr. Harris, and parents with a deathly sick child deemed purging and other invasive treatments appropriate. Physicians and parents no doubt worried about children’s fragile bodies suffering extra trauma, but the medical histories found in Folger MS W.a.87 showed very dire situations. The illnesses observed by Dr. Harris were in fact any parent’s worst nightmare. This manuscript is important evidence that parents could have reason to trust in seemingly dangerous purges that were disfavored by other physicians if it meant their children getting well again.

What Wafers?

ingredients laid out for lemon wafers

These are not vanilla wafers. These are not chocolate wafers. These are, I learned as I read the recipe, a different type of sweet. Might Dawson have been using an alternative definition? The Oxford English Dictionary defines wafers as we would today, describing them as “light, crisp cakes” or, in religious contexts, the Eucharistic host (Wafer, 1.a, 2). Dawson’s wafers lack a crucial wafer ingredient: flour. My sous chef and I forged ahead undaunted, but aware that making candy without a thermometer is challenging. More challenging still was our very un-English weather in North Carolina: 78 degrees, 84 percent humidity, and a falling barometer predicting rain. In short, not great candy making weather.

A few things caught my eye as I re-read: removing the wafers from paper using water, and the utter lack of any guidance in terms of the amount of sugar or lemon juice to be used. In the era of parchment paper, Silpats, and any number of nonstick sprays prying items off the pan is generally evidence of our own lack of preparation. For early cooks, however, options likely would have been more limited. Wetting the “rong side” of the paper to release something on its surface seemed like a practical trick that could be applied in other projects. I took the lack of guidelines for amounts as the chance to cook just using my eyes and the feel of the ingredients as we scooped and stirred.

The sugar left me with just a comparison for guidance- “the thickness of hunny.” In the first attempt, I imagined this as runny honey: my first mistake. The ratio of liquid to sugar was far too high. I cooked the juice of a lemon with sugar combined to the “runny honey” consistency in a small, non-stick pan over medium heat on an electric stove. Since I didn’t consider that this might be referring to a butter mint-style candy wafer, I skipped immediately to candy cooked to the hard ball (read: very clear and crisp) state. It is impossible to make this type of candy without boiling the mixture, so after a quick check of the OED to be sure I wasn’t missing some past definition of boil, I chose to ignore that direction. Perhaps she meant not to let it scorch?

This first attempt was a failure, as with the low amount of sugar, the mixture was a thick syrup and would not harden.

Effort two used the same mix but with longer cooking, this time in a metal spoon over the heat (I took Dawson rather literally here, to my peril!). No crisping and still a syrupy mess.

I decided to massively increase the sugar to more of a crystalized honey texture.

Bingo. The third wafer, also made in the spoon, took on some color and had a toffee-like consistency on the paper. Progress. For the next one, I let it go much longer, taking on a distinct golden color. My hope was to judge it to be at the hard ball stage. It’s possible to do this by putting a bit of the mix into cold water to see if a firm ball forms, but I got a bit distracted at this stage and forgot to check. Instead, knowing it takes a while to reach the appropriate temperature, I just let it boil significantly longer, to good effect. The third wafer was truly a crisp caramel sheet, which could be bent and its paper support pinned to give it a curve. This fourth wafer was so nicely crystalized that it slipped rather easily off the parchment lining, though I did paint some water on the back to help it along. This strategy seems promising with sweet foods.

I’m struck, in retrospect, with how much making this recipe today relies on analogy. Because I didn’t have the wafer candy Lisa used as a referent, I ended up with only my knowledge of grain-based wafers to go on, which was completely unhelpful. Since so much is left to prior knowledge, finding the right contemporary model to bridge this lack of period knowledge was crucial. While what I made was edible, tasty even, I think I’d use Lisa’s technique were I to try them again!

A Look Back at Dawson

After a whirlwind of transcribing activity far faster than Florence, the Dawson has complete keyings and we are moving on. But as we leave Dawson for the moment, we wanted to share a video of unboxing the the manuscript in the Folger Library reading room. It’s a lovely, slim volume with several recipes marked with Jane’s name, plus a do-si-dos structure.
